This report analyses RIDDOR based electricity-related accidents covering all industries and is intended to be an update (and standalone report) to the previous HSE research report ‘Identifying the incidence of electricity-related accidents in Great Britain’.
Using certain selection criteria, the full RIDDOR database from 1996/97 to 2008/09p was searched to identify three categories of electricity accident:
a) ‘direct contact’ with electricity; b) ‘electrical based’ accidents; and c) ‘all related’ accidents.
Analysis was carried out using RIDDOR fields such as ‘HSE year’, ‘work process’ and ‘agent’. A number of findings were revealed, including electrical fitters (including electricians) reporting the greatest number of fatalities and non-fatal injuries, with many of the accidents related to contact with electricity (or electrical discharge). However, a number of other accidents were not related to direct contact with electricity, such as handling strains/sprains and high falls. It is proposed that the results of this report constitute an updated evidence base indicating possible priority areas for intervention by the HSE.
This report and the work it describes were funded by the Health and Safety Executive (HSE). Its contents, including any opinions and/or conclusions expressed, are those of the authors alone and do not necessarily reflect HSE policy.

EXECUTIVE SUMMARY
INTRODUCTION AND OBJECTIVES
This report has been prepared by GL Noble Denton for the Health and Safety Executive (HSE)
as research contract OH1986, and describes a study on ‘Identifying the incidence of electricity-
related accidents in Great Britain – An update (1996/97 to 2008/09p)’.
In 2003, BOMEL Limited (now incorporated into and known as GL Noble Denton) was
commissioned by the HSE to produce a report looking at a dedicated data set relating to
electrical incidents extracted from the Reporting of Injuries, Diseases and Dangerous
Occurrences Regulations (RIDDOR) database covering 1996/97 to 2002/03. A pan-industry
electrical data set was created, analysed for trends, and the report provided as an evidence base
to inform HSE planning and risk reduction programmes. In 2010, the HSE re-approached GL
Noble Denton to request an update to the research to include data up to and including 2008/09p.
This report details the updated analyses and findings.
The overall aims of this project are to:
1. Develop an electricity-related accident data set from ‘supply to switch’ to provide a
baseline for measuring improvements across a range of industry sectors.
2. Analyse the electricity-related accident data to gain an insight into what type of
accidents occur, who was involved in them and what they were doing at the time.
3. Produce a report that contains analyses of the electricity-related accident data; identify
the key issues; and identify key priority areas for intervention.
DEVELOPMENT OF THE ELECTRICITY-RELATED ACCIDENT DATA SET
A data set containing electricity-related accidents was distilled from the Reporting of Injuries,
Diseases and Dangerous Occurrences Regulations 1995 (RIDDOR) accident database (covering
1996/97 to 2008/09p and consisting of over 1.9 million accidents).
The categorisation of RIDDOR reportable injuries is such that if an electrician fell from a ladder,
the accident may well be coded as a ‘fall’ even if it was contact with electricity that caused the fall.
Therefore, to gain better insight into all those accidents involving working with or around electricity
it is necessary to analyse a larger data set beyond those accidents that have been directly attributed to
electricity. Consequently, a data set was extracted from the main RIDDOR accident database.
The data set had three constituent parts:
Data set 1: ‘Direct contact’ with electricity – this data set is defined purely by the
RIDDOR accident kind categories ‘Electricity’ and ‘Volt’ (i.e. it only includes
accidents reported as being either an ‘Electricity’ or ‘Volt’ accident type).
v
Data set 2: ‘Electrical based’ (including ‘direct contact’) – this larger data set
contains the ‘direct contact’ accidents described above, as well as accidents reported
under other electricity-related RIDDOR categories (e.g. industries such as electricity
production, installation of wiring/fitting, manufacturing of electrical appliances;
occupations such as electrical engineers, electroplaters, etc.).
Data set 3: ‘All related’ accidents (including ‘electrical based’) – this is the full
data set containing the ‘electrical based’ accidents described above (i.e. all accidents
assigned an electricity-related RIDDOR code) and accidents brought in because their
associated accident narrative (i.e. the notifier comment or investigation report)
contains an electricity related keyword (e.g. ‘spark’, ‘plug’, ‘socket’, etc.).
The electricity-related accident data has been incorporated into the Electricity RIDDOR Report
Tool, which has been used for the analyses presented in Chapters 3, 4 and 5.
RESULTS AND CONCLUSIONS
The key results from each main data set reveal:
‘DIRECT CONTACT’ WITH ELECTRICITY ACCIDENTS
6% of all fatalities (168 deaths) over the 13 year period 1996/97 to 2008/09p, across
all industries may be due to direct contact with electricity or electrical shock.
A fluctuating picture in the fatal accidents from 1996/97 to 2008/09p, with a peak of
18 fatalities in 1999/2000. Encouragingly, non-fatal injuries have steadily decreased
over the years.
Overall, this means an average of 13 fatalities per year from 1996/97 to 2008/09p have
been caused by direct contact with electricity. Provisional data suggests that in
2008/09p there were 6 fatalities, which is the lowest number over the 13 years.
‘ELECTRICAL BASED’ ACCIDENTS
10% of all fatalities (287 deaths) over the 13 year period 1996/97 to 2008/09p, across
all industries may be linked to ‘electrical based’ accidents.
Overall, this means in all electrical based work activity from 1996/97 to 2008/09p,
there has been an average of 22 fatalities per year (i.e. accidents appearing under an
electrical RIDDOR category). Provisional data suggests that in 2008/09p there were
11 fatalities, which is the lowest number over the 13 years. As noted earlier, around
13 fatalities per year are due to direct contact with electricity, and additionally an
average of around 4 fatalities per year are due to falls (both high and other types of
falls).
vi
Yearly trends (HSE year):
A fluctuating picture in fatal accidents over the 13 year period 1996/97 to 2008/09p
with a peak of 34 fatalities in 1996/97 which reaches a low of 11 by 2008/09p.
Encouragingly, non-fatal accidents have steadily decreased year-on-year from 1996/97
to 2008/09p.
HSE sectors (Field operations directorate, FOD):
From 1996/97 to 2008/09p, the Construction HSE sector has the highest number of
fatal accidents (127). The Engineering and Utilities HSE sector reports the highest
number of non-fatal accidents (40,235).
Types of accident (Accident kind):
Over the 13 year period 1996/97 to 2008/09p, contact with electricity (or electrical
discharge) is main cause of fatalities (168), and is also relatively significant in non-
fatal injuries (although handling/sprains and trips are more common).
Focusing on the more recent years from 2001/02 to 2008/09p, contact with electricity
(or electrical discharge) is the main cause of fatalities (88), and has a role to play in
non-fatal accidents (3,887). Tripping over obstructions (5,507) and lifting/putting
down loads (3,902) play a more important role in non-fatal accident numbers.
Job role (Occupation):
From 1996/97 to 2001/02 and 2002/03 to 2008/09p, electric fitters (including
electricians) report the highest number of fatalities and non-fatal injuries.
Activity occurring at the time of the accident (Work process):
From 1996/97 to 2000/01, electrical activities have reported the second highest
number of fatal accidents (13), with general maintenance activities involved in the
highest number of fatalities (17). Non-fatal accidents are most commonly associated
with on-site transfer such as movement of persons and materials (7,898) and general
handling (7,345).
From 2001/02 to 2008/09p, electrical activities report the highest number of fatalities
(56), as well as highest number of non-fatal accidents (8,965).
Main object/movement involved in accidents (Agents):
From 1996/97 to 2000/01, unintentional contact with overhead lines and contact with
electricity/electrical discharge involved the highest number of fatalities (20 and 19
respectively). Moving heavy weights or strains/sprains contribute to the highest
numbers of non-fatal injury.
vii
From 2001/02 to 2008/09p, overhead lines are one of the main contributors to
fatalities (20), including other electricity cables which includes those trailing and
buried in walls (20). The greatest number of non-fatal injuries is also associated with
other electricity cables (5,936).
Age:
From 1996/97 to 2008/09p, fatalities are highest for those 25 to 34 and 40 to 54
(around 32 to 34 accidents in each age category). Non-fatal injuries increase from the
16 to 19 age group (3,800) to a peak by 35 to 39 (10,886), steadily decreasing
thereafter. Major injuries levels remain stable from 20 to 54 (around 2,000 accidents
in each age category).
‘ALL RELATED’ ACCIDENTS
40% of all fatalities (1,201 deaths) over the 13 year period 1996/97 to 2008/09p,
across all industries may be potentially linked to ‘all related’ accidents. However, due
to the possible tenuous link, caution should be exercised when using these figures.
Overall, this means in ‘all related’ accidents from 1996/97 to 2008/09p arising from
electrical based work and accidents indirectly related to electricity (where electricity
or electrical components feature in some way, although not necessarily causal in the
fatality), there has been an average of 92 fatalities per year. Provisional data suggest
that in 2008/09p there were 28 fatalities, which is the lowest number over the 13
years. As noted earlier, there is an average of 13 fatalities per year due to direct
contact with electricity, the same annual average number of accidents due to being
struck by moving, flying or falling objects, but less than the average of 18 fatalities
per year due to high falls (above 2 meters).
Yearly trends (HSE year)
A fluctuating picture in the number of fatalities over the 13 year period 1996/97 to
2008/09p, with a peak in 2007/08 (136), although fatalities fall dramatically in the
following year (28). From 2001/02 to 2008/09p, non-fatal accidents gradually
decrease from 19,504 to 14,257 by 2008/09p.
These findings indicate the success of efforts by HSE and industry to reduce electricity
related accidents.
HSE sectors (Field operations directorate, FOD):
From 1996/97 to 2008/09p, the Construction HSE sector reports the greatest number
of fatal accidents (427), followed by the Agriculture and Wood HSE sector (205). The
Construction HSE sector also reports the highest number of major injuries (12,448),
viii
and the Engineering and Utilities HSE sector reports the greatest total number of non-
fatal accidents (57,653).
Industry (SIC industry code):
From 1996/97 to 2008/09p, installation and fitting of electrical wiring reports 52
fatalities (and reports the greatest number of non-fatal accidents). The highest number
of fatalities is reported by the industry related to the construction of buildings and civil
engineering works (142).
Types of accident (Accident kind):
For the 13 year time period 1996/97 to 2008/09p, contact with electricity (or electrical
discharge) reports 168 fatalities, with the highest number of fatalities due to high falls
(233) and being struck by objects (174). The highest number of non-fatal injuries is
due to handling/sprains (51,456).
From 2001/02 to 2008/09p, contact with electricity (or electrical discharge) reports 88
fatalities, with high falls (125) being involved in the largest number of fatalities. Non-
fatal injuries are most commonly related to machinery, being hit by objects and trips
and slips (all above 10,000 accidents each).
Job role (Occupation):
From 1996/97 to 2001/02, electric fitters (including electricians) report the highest
number of fatalities (38) and highest number of non-fatal accidents (14,938).
Electrical engineers also report a high number of non-fatal injuries (8,074).
From 2002/03 to 2008/09p, electric fitters (including electricians) report the highest
number of fatalities (44) and non-fatal injuries (10,933).
Analysis shows that fatalities in electric fitters (including electricians) across the 13
year period 1996/97 to 2008/09p are predominantly related to contact with
electricity/electrical discharge (31) or high falls (20). Non-fatal injuries in this
population are often handling and sprains (7,454) and trips (5,908).
These results suggest a need to target electric fitters (including electricians), focusing
on best practice when working in direct contact with electricity, working at height, and
handling loads.
Activity occurring at the time of accident (Work process):
From 1996/97 to 2000/01, the highest number of fatalities involves general
maintenance activities (49) compared to less involvement from electrical activities
(13). The non-fatal injury trends show a similar pattern.
ix
From 2001/02 to 2008/09p, the involvement of electrical activities in fatalities is more
significant (56) although still less than manufacturing production (79) and machine
maintenance (74) activities. The non-fatal injury trends are similar.
Main object/movement involved in accidents (Agent):
From 1996/97 to 2000/01, unintentional contact with overhead lines (20) and direct
contact with electricity/electrical discharge (19) report some of the highest fatality
numbers, as do falls off moveable ladders (21). Electrical objects/movements do not
significantly feature in non-fatal injuries.
From 2001/02 to 2008/09p, the highest number of fatalities involves fork lift trucks
(33) and moveable ladders (28) rather than objects such as overhead power lines (20)
and other electricity cables (20). For non-fatal injuries, other electricity cables do play
a role (5,936), but it is less significant than other materials and machinery (11,519).
These results potentially indicate further consideration should be given to
interventions that do not merely focus on contact with electricity, but also working at
height (ladder use), and working around fork lift trucks and machinery.
Age:
From 1996/97 to 2008/09p, fatalities are highest for the 40 to 44 age group and 50 to
59 age group (above 137 fatalities in each age category). For non-fatal injuries,
accidents increase from 16 years of age (7,443) to a peak by the 35 to 39 age group
(22,930), decreasing thereafter. Major injuries remain relatively consistent (over
4,000) for the 20 to 24 age category through to the 55 to 59 age category.
It should be noted that this does not necessarily indicate that certain age groups are
more vulnerable to accident (since figures presented are frequencies rather than
calculated rates).
Employment status:
From 1996/97 to 2008/09p, three quarters of all fatalities have been reported for
‘employees’ (924), with fatalities in the ‘self-employed’ (250) constituting around
21% of all fatalities. Nearly all reported non-fatal injuries have been reported for
‘employees’ (180,899) compared to the ‘self-employed’ (4,195).
It should be noted that this does not necessarily indicate that certain types of
employment are more vulnerable to accident (since figures presented are frequencies
rather than calculated rates and the ‘self-employed non-fatal figures could also be
affected by under-reporting).
x
Monthly pattern:
From 1996/97 to 2008/09p, accumulatively the highest number of fatalities have been
reported for August (130), with significant numbers for January, and June through to
November. Significant numbers of non-fatal injuries (around 16,000 in each month)
have been reported for January, June, July and September through to November.
December reports the lowest number of non-fatal accidents (11,419).
These findings may provide some indication regarding the best time to launch media
campaigns or timely reminders throughout the year in order to reduce accident levels
further.
Types of injury:
From 1996/97 to 2008/09p, contact with electrical sources report the fourth highest
fatality numbers (145). Strains (53,554) and fractures (37,169) contribute more to
non-fatal injuries than injuries caused by electricity (4,183).
Region:
From 1996/97 to 2008/09p, the highest fatality numbers are reported for the ‘East and
South East’ (243) and the ‘Midlands’ (222). The non-fatal injury profile is similar.
At the local authority level from 1996/97 to 2008/09p, Manchester has the highest
fatality numbers (21) followed by Sandwell (16) and Birmingham (16). Birmingham
also reports the highest number of non-fatal injury (3,736) followed by Leeds (3,005),
with Manchester recording the fourth highest number of non-fatal injury (2,275).
With HSE insight into the resources available in different regions and cities, it may be
useful to compare any areas that report high accident levels with comparable regions
and cities that report lower levels. This exercise could yield further information into
best practice in certain areas that could be applied to other areas, particularly those
with high accident levels.
RECOMMENDATIONS
Some high level recommendations have been suggested based on the results of this research,
which include: considering existing knowledge and guidance around the identified risk areas;
HSE policy development work should be primarily based upon the ‘direct contact’ and
‘electrical related’ data sets; further analysis of notifier comments/investigation reports to gain
more understanding behind the key statistics reported; and further work undertaken to
understand areas of best practice that could be distilled from those regions of the country where
injury levels remain lower.

1. INTRODUCTION
1.1 INTRODUCTION
This report has been prepared by GL Noble Denton for the Health and Safety Executive (HSE)
as research contract OH1986, and describes a study on ‘Identifying the incidence of electricity-
related accidents in Great Britain – An update (1996/97 to 2008/09p)’.
1.2 CONTEXT OF THE STUDY
With the introduction of the ‘Revitalising Health and Safety’ (RHS) strategy statement in June
2000 by the Government and the then Health and Safety Commission (HSC), efforts have been
made by the HSE to work with industry to reduce the number of fatalities and major accidents,
cases of ill-health and the number of working days lost through work related injury and ill-
health. Percentage reduction targets have been set with the aim to achieve these targets by
2009/10.
The HSE has Electrical Specialist Groups working to investigate electrical related accidents
where the outcome has been serious (i.e. fatal or major injury), and to devise interventions to
protect those working with electricity. The Reporting of Injuries, Diseases and Dangerous
Occurrences Regulations 1995 (RIDDOR) is one key source of information they use to inform
their decision-making and intervention development. However, the categorisation of RIDDOR
reportable injuries is such that if an electrician fell from a ladder, the accident may well be coded as
a ‘fall’ even if it was contact with electricity that caused the fall. Therefore, to gain better insight
into all those accidents involving working with or around electricity it is necessary to analyse a
larger data set beyond those accidents that have been directly attributed to electricity. This provides
a broad data set that includes those workers that have suffered handling/sprain injuries, trips or falls
whilst undertaking electricity-related work as well as those injured through contact with electricity.
As a result, best use can be made of HSE resources in targeting groups of workers involved in
activities such as cabling, where HSE’s falls from height, slips and trips, and musculoskeletal
disorder priority programmes may want to get their messages over to the same group.
Since these considerations were the basis of a 2003 study commissioned by the HSE and
undertaken by BOMEL Limited (now incorporated into and known as GL Noble Denton), there
is a need to update the data range to cover years up to and including 2008/09p, and to draw
appropriate conclusions. This report supersedes the original 2003 report1, and has been written
as a standalone document, and is intended to be referred to without the need to access the
original report.
1.3 OBJECTIVES AND SCOPE OF WORK
The full electricity-related accident data has been incorporated into the Electricity RIDDOR
Report Tool, which has been used for the analyses presented in this report.
The overall objectives of this study are to:
1. Develop an electricity-related accident data set from ‘supply to switch’ to provide a
baseline for measuring improvements across a range of industry sectors.
1
2. Analyse the electricity-related accident data to gain an insight into what type of
accidents occur, who was involved in them and what they were doing at the time.
3. Produce a report that contains analyses of the electricity-related accident data; identify
the key issues; and identify key priority areas for intervention.
1.4 SCOPE OF THIS REPORT
The study is presented in the report as follows:
Chapter 2 provides brief summary details about how the electricity data set was
created and divided into three component data sets.
Chapter 3 presents the analyses of the ‘direct contact’ with electricity (or electrical
discharge) data set.
Chapter 4 presents the analyses of the ‘electrical based’ data set.
Chapter 5 presents the analyses of the entire data set (termed the ‘all related’ data set).
Chapter 6 highlights the main conclusions.
Chapter 7 provides overall study recommendations.
Chapter 8 contains the references used in the main body of this report.
Appendix 1 provides a more in-depth description of how the electrical data set was
created from the RIDDOR database.
1.5 HOW TO USE THIS REPORT
1.5.1 The data sets used
The analysis has been undertaken in stages on the electricity data set, as reflected in Figure 1. It
can be seen that each successive chapter focuses on a different data set. Different audiences
will have different interests and accordingly focus on certain chapters of the report. For
instance, it is anticipated that the HSE Electrical Specialists Groups will be most interested in
Chapter 3 and Chapter 4 as these contains accidents that have been assigned an electricity
related RIDDOR code. Whilst other HSE groups may find Chapter 5 more useful as this takes
into consideration accidents that are less directly related to electricity. Chapter 2 provides an
outline of how the data sets were created and defined.

In addition, fatal accident numbers are indicated in purple, major injuries in burgundy and over-
3-day injuries in yellow. A key message (element two) is presented giving an overview of the
result, followed by a graph either illustrating fatalities, or major and over-3-day injuries
(element three). It should be noted that fatality trends are shown in separate graphs from major
and over-3-day accidents. A table is presented where appropriate to provide further detail
(element four). A final piece of text concludes the analysis (element five) and provides further
detail behind the key message.

2. CREATION OF THE ELECTRICITY ACCIDENT DATA SET
2.1 INTRODUCTION
This chapter of the report briefly describes how the electricity data set was initially created and
then developed into three separate component data sets for more focused analysis. It also
outlines some of the limitations of the data set, as well as the HSE’s RIDDOR data, which the
data set is based upon. These activities address Objective 1:
Develop an electricity-related accident data set from ‘supply to switch’ to provide a
baseline for measuring improvements across a range of industry sectors.
2.2 CREATION OF THE DATA SET
A data set containing electricity-related accidents was created using workplace accidents
reported via the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995
(RIDDOR). The HSE’s RIDDOR accident database covered the years 1996/97 to 2008/09p and
contained over 1.9 million accident records. This was provided by HSE to GL Noble Denton
under its technical support agreement.
A two-prong approach was used to extract electricity-related accidents from the main RIDDOR
database:
All reported accidents assigned one or more electricity-related RIDDOR code (e.g. the
type of accident was reported as ‘Volt’ or the occupation of the injured person was an
‘electrical fitter’) were included in the data set.
All reported accidents with an associated narrative description (i.e. a notifier comment
or an investigation report) that included an electricity-related keyword (e.g. ‘fuse’ or
‘socket’) were included in the dataset.
This two-pronged approach ensured those accidents that were explicitly coded by RIDDOR as
being electricity-related, as well as those that had not been coded using electricity-related
RIDDOR codes, but were related to electricity as illustrated in the associated narrative
description, were both included in the data set. This provided the HSE team with a broader
insight into where electrical incidents are occurring and how working with other HSE
programmes (e.g. the falls team) may assist in targeting electricity-related accidents.
A detailed description of how the electricity dataset was created can be found in Appendix 1.
2.3 DATA SET COMPONENTS
Creation of the electricity-related data set (as described above) generated a total of 187,240
reported accidents and provided one main data source for the HSE’s electrical team. However,
the data set also contained a mixture of reported accidents that were both directly, and
indirectly, related to electricity. In order to provide the HSE team with a clearer picture of
4
electricity related accidents, the main dataset was developed into two further subsidiary data
sets. In total, this equated to three separate data sets, defined as follows:
Data set 1: ‘Direct contact’ with electricity – this data set is defined purely by the
RIDDOR accident kind categories ‘Electricity’ and ‘Volt’ (i.e. it only includes
accidents reported as being either an ‘Electricity’ or ‘Volt’ accident type).
Data set 2: ‘Electrical based’ (including ‘direct contact’) – this larger data set
contains the ‘direct contact’ accidents described above, as well as accidents reported
under other electricity-related RIDDOR categories (e.g. industries such as electricity
production, installation of wiring/fitting, manufacturing of electrical appliances;
occupations such as electrical engineers, electroplaters, etc.). For a full list of the
RIDDOR categories under this definition, please refer to Table 62 to Table 66 in
Appendix 1.
Data set 3: ‘All related’ accidents (including ‘electrical based’) – this is the full
data set (as described in Chapter 5), containing the ‘electrical based’ accidents
described above (i.e. all accidents assigned an electricity-related RIDDOR code) and
accidents brought in because their associated accident narrative (i.e. the notifier
comment or investigation report) contains an electricity related keyword (e.g. ‘spark’,
‘plug’, ‘socket’, etc.). For a full list of the keywords used under this definition, please
refer to Table 67 in Appendix 1.
The number of accidents generated in each of the three data sets is shown in Table 1. Each data
set is represented by a coloured column and compared against the number of accidents reported
in all industries over the 13-year time period.

Table 1 highlights that the ‘direct contact’ data set contains 7,632 reported accidents, of which
168 are fatal injuries. This means accidents involving direct contact with electricity account for
6% of fatal accidents across all industries. The ‘electrical based’ data set contains 287 fatal
5
injuries, accounting for 10% of fatal accidents across all industries and the ‘all related’ data set
contains 1,201 fatal injuries, accounting for 40% of fatal accidents across all industries.
However, some caution should be exercised when interpreting the figures for the ‘all related’
data set, as this data set does contain a number of accidents that are only indirectly related to
electricity. It is therefore recommended that any HSE policy development work is primarily
based upon the ‘direct contact’ and ‘electrical related’ data sets, as these contain accidents
assigned electricity-related RIDDOR codes only.
2.4 DATA SET LIMITATIONS
There are some potential limitations to the electricity data sets that should be highlighted, as
follows:
The keyword search approach is not a perfect science, but it is a means to efficiently
build a data set, considering the full RIDDOR database consists of over 1.9 million
accident records for the period 1996/97 to 2008/09p.
The ‘all related’ data set is highly dependent on the contents of notifier comments and
investigation reports, as well as the keyword search terms (see Table 67). Any
accident not assigned an electricity-related RIDDOR code will not be included in the
‘all related’ data set unless it has an electricity-related keyword present in the accident
narrative. Equally, there may be a number of accidents included in the data set
because their notifier comment or investigation report contains a keyword, even
though the accident may not have any real association with electricity.
There may be under-reporting of less severe incidents (which can potentially exist in
all industries). Consequently, the RIDDOR data/figures on minor accidents (over-3-
day and some major accidents) presented may be lower than is the real case.
2.5 RIDDOR DATA LIMITATIONS
To remain current and reflect changes to HSE internal operations and external industry
developments, the HSE has periodically needed to amend the codes used in RIDDOR fields,
more specifically:
Work process, Agent, and Accident Kind fields – coding changed in 2001/02 due to
the implementation of the Incident Contact Centre (ICC)
Occupation field – coding changed in 2002/03 due to change in the Standard
Occupational Classification (SOC)
All remaining RIDDOR fields – stayed the same throughout the 13 years from
1996/97 to 2008/09p.
6
For the affected fields the graphs have been split into two (this is clearly stated in the report).
For example, graphs will represent the ‘pre-ICC’ and ‘post-ICC’ timeframe because there is no
mapping between the pre-ICC and ICC system.
Finally, it should be noted that the data reported for each year is final data (i.e. it has undergone
a process of verification by HSE). The only exception is for the year 2008/09p, which is
differentiated on the graphs with a ‘p’ for ‘provisional’. This data was provisional at the time of
writing this report and therefore may be subject to minor future amendments following HSE
verification.

3. MAIN ANALYSIS OF ACCIDENTS INVOLVING ‘DIRECT
CONTACT’ WITH ELECTRICITY
3.1 INTRODUCTION
This chapter helps to address Objective 2, which is to:
Analyse the electricity-related accident data to gain an insight into what type of
accidents occur, who was involved in them and what they were doing at the time.
The analyses presented in this chapter relates to the ‘direct contact’ with electricity data set,
which are accidents that have been categorised as either ‘volt’ or ‘electricity’ under the
RIDDOR accident kind code. More specifically, Table 2 highlights the column of data that is
being presented in this chapter. It suggests that around 6% of all fatal accidents (across all
industries) have been caused by direct contact with electricity, amounting to 168 fatalities over
the 13 year period.

4. MAIN ANALYSIS OF ‘ELECTRICAL BASED’ ACCIDENTS
4.1 INTRODUCTION
This chapter also helps to address Objective 2, which is to:
Analyse the electricity-related accident data to gain an insight into what type of
accidents occur, who was involved in them and what they were doing at the time.
This chapter presents analysis on the ‘electrical based’ accidents data set, defined by all
electricity related RIDDOR categories. More specifically, Table 4 highlights the column of data
that is being presented in this chapter. It suggests that around 10% of all fatal accidents (across
all industries) are ‘electrical based’, which amounts to 287 fatalities across the 13 years.

It is anticipated that this chapter will be of direct interest to those working in the Electrical
Specialist Groups in the HSE. This is because only the main RIDDOR electricity-related
categories are contained within the ‘electrical based’ data set and have been graphically
illustrated in this chapter, by: HSE year, field operations directorate, ‘accident kind map’ (and
‘accident kind’), occupation, work process, agent and age.

Figure 9 and Table 8 show that contact with electricity or electrical discharge (as shown by the
‘Volt’ bar) have clearly caused the highest number of fatalities (168 constituting around 59% of
all ‘electrical based’ fatalities over the 13 year period).
The next most common type of accident associated with fatal accidents, albeit it much lower
than the ‘volt’ category, relates to high falls (37 deaths).
17
Key message
Accidents caused by contact with electricity or electrical discharge (‘Volt’) are actually the
most common type of non-fatal accident, with handling/sprains the most common,
followed by trips and being struck by objects.

Figure 10 and Table 9 show that contact with electricity or electrical discharge (shown by
‘Volt’) is the fourth most common accident kind map category (7,464 accidents) involved in
non-fatal accidents. Handling (including lifting and carrying) and sprains (including strains)
18
are the most common accident kind with 27,249 accidents. Trips (20,065) and being struck by
an object (10,313) are the next most common kinds of accident.
19
Types of ‘electrical based’ accident (Accident kind)
‘accident kind’ classification was introduced by the HSE as part of the
new Incident Contact Centre (ICC) to provide more detailed categories to classify the kind of
accidents being reported. For instance, handling and sprains was divided to include lifting,
putting down, handling, sharp objects, outward body movements and other handling activities.
This category therefore covers the last eight years up to 2008/09p (i.e. ‘post ICC’).
electricity (or electrical discharge) is the main cause of fatalities, with high falls
featuring as important but at a much lower number than electricity

Figure 11 and Table 10 show that fatalities were by far the highest for the ‘electricity’ accident
kind category (88). This further supports the view that direct contact with electricity or
electrical discharge is one of the main causes of fatal accidents.
In comparison, high falls report the second highest level albeit at a much reduced number of 21
fatalities, and falls from an unspecified height also have a reasonable number of fatalities (10).
21
Key message
caused by contact with electricity (or electrical discharge) are the third most
common type of accident leading to non-fatal injuries, and non-fatal injuries from trips over
obstructions, and lifting/putting down loads are more common.

Figure 12 and Table 11 show that contact with ‘electricity’ (or electrical discharge) is the third
most common type of accident leading to non-fatal injury.
Trips over obstructions (e.g. furniture, small items, work materials, boxes, and waste) are the
most prevalent kind of accident with 5,507 total non-fatal accidents.
‘Lift putdown’ (injury through lifting or putting down loads) and ‘other trip’ (slipped, tripped or
fell on the same level in another way not specified elsewhere - includes lost footing on kerb
stone/steps or on raised thresholds) are also as common as contact with electricity/electrical
discharge, with each reporting around 3,800 total non-fatal accidents.
23
‘Electrical based’ accidents by job role (Occupation)
The Standard Occupational Classification (SOC) is a means of classifying all occupations in
Great Britain. This has been subject to updates and in April 2002 the SOC 2000 was adopted.
Consequently, from 2002/03 and beyond, the occupations of those injured at work were
recorded using the SOC 2000 system. This necessitates splitting the illustration of job role to
cover 1996/97 to 2001/02 (‘pre SOC’) and 2002/03 to 2008/09p (‘post-SOC’). The section that
follows begins with the pre-SOC period.
Key message
Electric fitters have reported the highest number fatal accidents with the second highest fatal
accident level reported by electrical engineers.

Figure 14 and Table 13 show that again, it is clear that electric fitters reported the highest
number of injuries with 14,938 total non-fatal accidents.
Electrical engineers also have a significant number of total non-fatal accidents (8,074) followed
by other routine operatives (2,572).
27
The section that follows illustrates the accidents that occurred post-SOC sorted by occupation.
Similar to the period before the introduction of SOC 2000, electric fitters reported the highest
fatality numbers by far, with a number of labourers in the construction trade not elsewhere
reporting the second highest number of fatal accidents.

Figure 15 and Table 14 show that similar to the results from the pre-SOC classification (as was
seen in Figure 13), electrical fitters report the greatest number of fatalities (44).
Of interest, the second highest number of reported fatal accidents (10) are reported for
‘Labourer oth’ (labourers in other construction trades n.e.c. (not elsewhere classified)), with
electrical engineers (7) and electrical engineers n.e.c. (6) reporting similar numbers.
In order to present the data succinctly, the table only shows occupations that have reported two
or more ‘electrical based’ fatalities.
29
Key message
Similar to the fatal injuries profile, electric fitters have reported the most non-fatal injuries.
Electrical engineers have the third highest number of non-fatal accidents although this is much
lower than electric fitters.

Figure 16 and Table 15 show that the pattern is similar to the fatality picture, with electric fitters
reporting the highest numbers with 10,933 non-fatal accidents.
Process operatives report the next highest number of non-fatal accidents (3,191), followed by
electrical engineers (2,240), although these are much lower than the number reported by electric
fitters.

Activity occurring at the time of the ‘electrical based’ accident (Work
Process)
ICC also caused the ‘work process’ classification to change in 2001. The data
covering the pre-ICC period is presented first, followed by the post-ICC period.
Key message
Electrical activities have reported the second highest number of fatal accidents, which is slightly
lower than the number of fatalities reported by general maintenance activities.

Figure 17 and Table 16 show that electrical work processes have the second highest number of
fatalities (13), after general maintenance (including repair, renovation, cleaning activities at
temporary locations, inspection; excluding building maintenance) with 17 fatalities.
Distribution networks (including electricity, gas, water, telecommunications and postal, meter
reading, mail collection, delivery and sorting) also have a relatively high number of fatalities
(8).
In order to present the data succinctly, the table only shows work processes that have reported
two or more ‘electrical based’ fatalities.

Figure 18 and Table 17 clearly show that on-site transfer (including movement of persons,
patients walking, materials or part finished items between processes by pump, conveyor;
manual or mechanical means) and general handling have the highest total non-fatal accident
levels (each with over 7,300 accidents). In comparison, electrical work processes are ranked
ninth in the table (1,734).
35
Following the introduction of the ICC coding system, the following two graphs illustrate the
dominant work process for the eight years between 2001/02 to 2008/09p.
By far, electrical activities have reported the highest number of fatal accidents, with the second
greatest number of fatalities being reported for machine maintenance.

Figure 19 and Table 18 show that electrical activities occurring at the time of accident report the
highest fatal accident numbers (56).
In comparison, machine maintenance and surface treatment (painting, decorating, plastering,
flooring, plumbing, joinery) report 20 and 12 fatalities respectively.
In order to present the data succinctly, the table only shows work processes that have reported
two or more ‘electrical based’ fatalities.

Figure 20 and Table 19 show that again, electrical work processes have reported the greatest
number of non-fatal accidents (8,965).
A very similar number of non-fatal accidents are also reported for ‘Prod manufacture’
(manufacturing production associated with the industry [SIC] of the workplace for: food
products, drink, tobacco, textiles, clothing, leather, amongst others) with 8,089 total non-fatal
accidents.
Machine maintenance features again for non-fatal injuries, with the third highest number of total
non-fatal accidents (4,644).
39
Main object or movement involved in ‘electrical based’ accidents (Agent)
The new ICC also caused the ‘agent’ category to change in 2001. The data covering the pre-
ICC period is presented first, followed by the post-ICC period.
Unintentional contact with overhead lines and contact with electricity/electrical discharge report
the greatest number of fatalities.

Figure 21 and Table 20 show that ‘Vo ohlines’ (overhead lines - unintentional contact) and
‘Volt’ (contact with electricity or electrical discharge) have reported 20 and 19 fatalities
respectively.
‘Vo plant’ (industrial plant, vessels or equipment) additionally reports a high level of fatalities
(11).
In order to present the data succinctly, the table only shows main objects/movements that have
reported two or more ‘electrical based’ fatalities.

Key message
The picture is quite different from the fatal accident profile, with electrical contact or electrical
equipment incidents not featuring in the most common objects/movements involved in non-fatal
In fact, the most common injuries relate to moving heavy weights or strains/sprains.

Figure 22 and Table 21 show that the picture is quite different to the fatal accident findings
(shown in Figure 21). Objects/movements related to sprains and strains involved in handling
objects occupy the top end of the graph. More specifically, ‘Hs weight’ (lifting or moving [inc
throwing] heavy weights) and ‘Hs awkward’ (strains or sprains etc. not involving handling or
lifting e.g. awkward movement) each report over 3,000 total non-fatal accidents.
‘Hs sharp’ (injuries or cuts from handled material including trapped fingers under item being
handled) and handling/sprains are ranked third and fourth respectively (excluding the
‘unknown’ category) based on total numbers of non-fatal accidents.

It should be noted that since these figures reflect frequencies and not rates, it is not necessarily
the case that these age groups are the most at risk.

Key message
There is a gradual increase in the total non-fatal injuries from the 16 to 19 age group through to

5. MAIN ANALYSIS OF THE ‘ELECTRICITY-RELATED’
ACCIDENT DATA
5.1 INTRODUCTION
This chapter completes the analyses to address Objective 2, which is to:
Analyse the electricity-related accident data to gain an insight into what type of
accidents occur, who was involved in them and what they were doing at the time.
This chapter presents the analyses of the full electricity-related data set, termed the ‘all related’
data set. This is defined by electricity -related RIDDOR categories as well as those accidents
where their associated narratives (i.e. notifier comments / investigation reports) contain
electricity-related keywords (see Appendix 1 for a list of the keywords). As such, the data set
contains accidents directly related to electricity, as well as those that are related to electricity,
but where contact with electricity was not the main cause. Examples of these accidents include,
tripping over electrical wiring, battery acid burns, injury from power tool use, asphyxiation
from smoke generated from electrical faults, etc.
Table 25 highlights the column of data that is analysed and presented in this chapter. It
indicates that 40% of all fatal accidents (across all industries) could have some connection with
electricity. For example, they may be due to direct contact with electricity, or in other cases due
to instances where electricity is not the primary cause but is in some way connected to the
accident.

NB: data highlighted in colour has been presented in this chapter
It is advised that some caution should be exercised when interpreting the figures for the ‘all
related’ data set, as this data set does contain a number of accidents that are only indirectly
related to electricity. It is therefore recommended that any HSE policy development work is
primarily based upon the ‘directcontact’ and ‘electrical related’ data sets, as these contain accidents assigned electricity-related RIDDOR codes only.

Figure 27 and Table 26 show that the pattern of fatalities has fluctuated from year to year. It is
important to note that the time from 1996/97 to 2000/01 should not be directly compared to the
time from 2001/02 to 2008/09p. This is due to the introduction of notifier comments in 2001,
which required the notifier to describe the accident. As the ‘all related’ data set contains
accidents with an electricity related keyword in their notifier comment, it is expected that from
51
2001/02 the ‘all related’ accident data set would contain more accidents due to the introduction
of notifier comments.
From 2001/02 onwards, it can be reliably deduced that fatal accident numbers do fluctuate, and
reach a peak in 2007/08 (136) but then dramatically fall in 2008/09p. However, it should be
viewed with caution given that the figures for 2008/09 have yet to be finalised by HSE.
52
Key message
The increase in accidents from 2000/01 to 2001/02 is not due to a real increase in non-fatal
accidents, rather a result of more accidents being pulled in for analysis with the introduction of
notifier comments as part of RIDDOR. However, there real evidence of a decrease in non-fatal
accidents following 2001/02.

Figure 28 and Table 27 show ‘all related’ accidents by year. The data indicates a sharp rise in
the overall accident numbers from 2001/02 onwards. As with the fatal accidents, this can be
explained by the introduction of ICC notifier comments (and thus identification of additional
accidents and injuries from the keyword search which has been conducted on notifier
comments) producing the pattern in Figure 28 and Table 27. As such, the increase in the total
non-fatal injury bar from 2000/01 to 2001/02 is not due to increased incidence in accidents per
se.
12.130883.00\04\001R Rev 3 September 2010 53
2001/02 the ‘all related’ accident data set would contain more accidents due to the introduction
of notifier comments.
From 2001/02 onwards, it can be reliably deduced that fatal accident numbers do fluctuate, and
reach a peak in 2007/08 (136) but then dramatically fall in 2008/09p. However, it should be
viewed with caution given that the figures for 2008/09 have yet to be finalised by HSE.

High falls (i.e. above 2 metres) are the type of accident reporting the highest number of fatalities
(233), followed by being struck by moving, flying or falling objects (including accidents
involving powered hand tools or accidental assault such as horseplay) (174 fatalities).
62
Key message
ontact with electricity or electrical discharge (‘Volt’) is responsible for relatively few non-fatal
accidents (it is ranked seventh compared with other types of accident). Handling and sprains are
the most common type of accident.

Figure 34 and Table 33 show that handling and sprains are the most common non-fatal accident
type (51,456), followed by trips (37,137) and being struck by falling objects (24,474).
63
Contact with electricity or electrical discharge (‘Volt’) in comparison reports relatively few
accidents and is ranked seventh in terms of the total number of non-fatal accidents (7,464).
64
From 2001/02, a new ‘accident kind’ classification was introduced by HSE as part of the new
Incident Contact Centre (ICC) to provide more detailed categories to classify the kind of
accidents being reported. For instance, handling and sprains divided to include lifting, putting
sharp objects, outward body movements and other handling activities. It
covers the last eight years up to 2008/09p.
Contact with electricity or electrical discharge (‘Electricity’) is the second highest type of fatal
accident, behind high falls (over 2 metres).

Figure 36 and Table 35 show that the ‘machinery’ accident types (contact with moving
machinery or material being machined) is the most frequent type of accident associated with
non-fatal injuries (10,892).
Very similar levels of total non-fatal accidents are found for ‘other-hit object’ (hit by a moving,
flying or falling object, which could not be specified in other categories) and ‘other trip’ (such
as lost footing on kerb stones/steps) amounting to over 10,000 accidents each.
The ‘electricity’ accident type (3,887) actually ranks 14th
in Table 35, which is quite different
from the fatality profile of this type of accident (seen in Figure 35).
68
‘All related’ accidents by job role (Occupation)
This section shows the number of ‘all related accidents split by occupation reported between
1996/97 and 2001/02 using the categories existing for that time under the pre-SOC 2000
(Standard Occupational Classification) system.
Key message
The role of electric fitters (including electricians) reported the highest number of fatal accidents,
closely followed by maintenance fitters (craft and related manual operations) and agriculture
managers (and administrators).

Figure 37 and Table 36 show that electric fitters (including electricians) are the group reporting
the greatest number of fatal accidents (38).
Maintenance fitters (craft and related manual operations) and agriculture managers (and
administrators) also report significant numbers of fatal accidents (36 and 34 respectively).
Electrical engineers (‘Engine/elec’) defined by RIDDOR as ‘other occupations (labouring),
mining, manufacturing and construction, agriculture’, is ranked 11th in the table (15 fatalities).
70
Key message
Electric fitters (including electricians) is the occupation that has reported the greatest number of
non-fatal accidents, nearly double that of the second highest number of accidents reported by
the ‘engine/elec’ occupation.

Figure 38 and Table 37 show that electrical fitters (including electricians) are the occupation
that has reported the greatest number of non-fatal accidents (14,938), a conclusion that agrees
with the fatal accident profile (as shown in Figure 37).
Interestingly, electrical engineers (‘Engine/elec’) report the second highest number of non-fatal
accidents (8,074), despite a relatively low fatality level as indicated earlier.
72
The Standard Occupation Classification (SOC 2000) was adopted from 2002/03, and therefore
the data shown below covers the period from 2002/03 to 2008/09p.
(including electricians), report the highest number of fatal accidents of any
group. A significant number of fatal accidents are also reported by the
industry, specifically labourers (in other construction trades not elsewhere
classified) and construction trades not elsewhere classified.

Figure 39 and Table 38 show that electric fitters (including electricians) are the group reporting
the greatest number of fatal accidents (44) (as also reported under the pre-SOC system, shown
in Figure 37).
Construction occupations also report significant numbers of fatal accidents, with labourers (in
other construction trades not elsewhere classified) reporting 35 fatalities, and construction trades
not elsewhere classified reporting 28 fatalities.
74
Key message
Similar to the fatality profile, electrical fitters (including electricians) have reported the most
non-fatal accidents of any occupation. Electrical engineers report a number of accidents, but
these are low in comparison to electrical fitters.

Figure 40 and Table 39 show that electrical fitters (including electricians) report the most non-
fatal accidents (10,933) which correspondents to the fatality profile (as shown in Figure 39).
Process operatives (not elsewhere classified) report the second highest total non-fatal accident
levels (8,939) followed by ‘Oth storage hand’ (other goods handling and storage occupations
not elsewhere classified) which reports 7,077 total non-fatal accidents.
Electrical engineers do feature in 10th
place, but in comparison to electrical fitters report a much
lower total non-fatal accident number (2,240).

78
Handling and sprains make up the highest total non-fatal accident number (7,454). Trips are
also common (5,908).
It would appear that trips and low falls are responsible for the highest frequency of major
injuries for electric fitters over the 13 year time period.

Figure 43 and Table 41 show that involvement of electrical activities in fatal accidents has been
relatively infrequent (13 fatalities and ranked joint seventh in the table).
The most common activities involved in fatal accidents are general maintenance (including
repair, renovation, cleaning activities at temporary locations, inspection; excluding building
maintenance) which involved 49 fatalities; on-site transfer (transfer [on site] including
movement of persons, patients walking, materials or part finished items between processes by
pump, conveyor; manual or mechanical means) which involved 32 fatalities; and
loading/unloading (30 fatalities).
81
Key message
Similar to the fatal accident profile, electrical activities have been responsible for fewer non-
fatal accidents than a range of other activities such as on-site transfer and general handling.

fatal accident profile (as shown in Figure 43), whereby electrical accidents do feature (1,734
accidents and ranked ninth), but are comparatively infrequent in relation to other activities.
The activities that have been involved in the greatest total number of non-fatal accidents are
mainly on-site transfer (8,652) and general handling (8,404).

Figure 47 and Table 45 show that falls off moveable ladders (including step ladders) are the
category of object/movement responsible for most fatal injuries (21). However, electricity
related objects/movements contribute a similar number of fatal accidents, specifically ‘Vo
ohlines’ - unintentional contact overhead power lines (20) and ‘Volt’ - direct contact with
electricity/electrical discharge (19).

Figure 49 and Table 47 show that forklift trucks have been responsible for the greatest number
of fatal accidents (33), followed closely by moveable ladders (28) and other heavy goods
vehicles (27).
Contributing to a much lower incidence of fatal accidents, but associated with electricity are
overhead power lines and ‘Oth elec cab’ (other electricity cables including those trailing or
buried in walls) which are each responsible for 20 fatalities and ranked joint sixth.
93
Key message
Other electricity cables including those trailing or buried in walls reports the fourth highest level
accidents, with other materials and machines, floors (including pavements and
roads) and the injured person themselves contributing to most non-fatal accidents.

Figure 54 and Table 52 show that nearly all accidents (180,899) have occurred to those classed
as an ‘employee’ (97% of all non-fatal accidents). In addition, 25% of these accidents are
classed as major. The ‘self-employed’ have comparatively a much smaller number of total non-
fatal accidents (4,195), but over half of these accidents (58%) are major injury accidents.
However, despite this seemingly clear trend, some caution must be exercised when interpreting
these figures. ‘Employees’ are far more likely to report non-fatal accidents (it is likely to be
required by their employers) than the ‘self-employed’. This therefore is likely to have affected
the non-fatal accident trend. This is also different to fatal accidents, which will always be
reported eventually regardless of employment status.

Figure 62 and Table 60 show that the highest number of total non-fatal accidents have been
reported by Birmingham (3,736), followed by Leeds (3,005) and then Glasgow (2,548).
Manchester has the fourth highest total number of non-fatal accidents (2,275) but as seen earlier
(as shown in Figure 61) it records the highest fatality level of any local authority.
Interestingly, Sandwell may have the same fatal accident level as Birmingham (as shown in
Figure 61), but in terms of total non-fatal accidents, Sandwell (1,317) has less than half of the
number of accidents reported by Birmingham and is ranked 14th in Table 60.

6. CONCLUSIONS
In relation to the initial project objectives, the following conclusions can be drawn from the
work undertaken in this research to:
Objective 1: Develop an electricity-related accident data set from ‘supply to switch’
to provide a baseline for measuring improvements across a range of
industry sectors.
1. A data set containing electricity-related accidents was created using workplace
accidents reported via the Reporting of Injuries, Diseases and Dangerous Occurrences
Regulations 1995 (RIDDOR).
2. The main data set contained reported accidents that were assigned an electricity-
related RIDDOR code, as well as those that were indirectly related to electricity as
their associated narrative included an electricity-related keyword. This provided the
HSE team with a broader insight into where electrical incidents are occurring and how
working with other HSE programmes (e.g. the falls team) may assist in targeting
electricity-related accidents.
3. In order to provide the HSE team with a clearer picture of electricity related accidents,
the main data set was developed into two further subsidiary data sets. In total, this
equated to three separate data sets, defined as follows:
Data set 1: ‘Direct contact’ with electricity – this data set was defined
purely by the RIDDOR accident kind categories ‘Electricity’ and ‘Volt’ (i.e.
it only included accidents reported as being either an ‘Electricity’ or ‘Volt’
accident type).
Data set 2: ‘Electrical based’ (including ‘direct contact’) – this larger data
set contained the ‘direct contact’ data set, as well as accidents reported under
other electricity-related RIDDOR categories (e.g. industries such as
electricity production, installation of wiring/fitting, manufacturing of
electrical appliances; occupations such as electrical engineers, electroplaters,
etc.).
Data set 3: ‘All related’ accidents (including ‘electrical based’) – this was
the full data set, containing the ‘electrical based’ data set (i.e. all accidents
assigned an electricity-related RIDDOR code) and accidents brought in
because their associated accident narrative (i.e. the notifier comment or
investigation report) contained an electricity related keyword (e.g. ‘spark’,
‘plug’, ‘socket’, etc.).
4. The ‘direct contact’ data set contained 7,632 reported accidents, of which 168 were
fatal injuries (accounting for 6% of fatal accidents across all industries). The
110
‘electrical based’ data set contained 287 fatal injuries, accounting for 10% of fatal
accidents across all industries and the ‘all related’ data set contained 1,201 fatal
injuries, accounting for 40% of fatal accidents across all industries. However, caution
should be exercised when interpreting the figures for the ‘all related’ data set, as this
data set does contain a number of accidents that are only indirectly related to
electricity.
5. There were also some limitations to the ‘all related’ data set as there was such high
reliance upon the quality of the text contained within notifier comments and
investigation reports. There were also limitations with the HSE’s RIDDOR data,
particularly due to changes in coding within certain RIDDOR fields during the 13-year
period.
Objective 2: Analyse the electricity-related accident data to gain an insight into what
type of accidents occur, who was involved in them and what they were
doing at the time.
‘DIRECT CONTACT’ WITH ELECTRICITY ACCIDENTS
6. 6% of all fatalities (168 deaths) over the 13 year period 1996/97 to 2008/09p, across
all industries may be due to direct contact with electricity or electrical shock (see
Table 2).
7. There is a fluctuating picture in the number of fatal accidents over the 13 year period
1996/97 to 2008/09p with a peak of 18 fatalities in 1999/2000 (see Figure 3).
8. Non-fatal injuries have steadily decreased since 1996/97 (from 746 total accidents to
424 by 2008/09p) (see Figure 4).
9. Overall, this means an average of 13 fatalities per year from 1996/97 to 2008/09p have
been caused by direct contact with electricity. Provisional data suggests that in
2008/09p there were 6 fatalities, which is the lowest number over the 13 years.
‘ELECTRICAL BASED’ ACCIDENTS
10. 10% of all fatalities (287 deaths) over the 13 year period 1996/97 to 2008/09p, across
all industries may be linked to ‘electrical based’ accidents (see Table 4).
11. Overall, this means in all electrical based work activity from 1996/97 to 2008/09p,
there has been an average of 22 fatalities per year (i.e. accidents appearing under an
electrical RIDDOR category). Provisional data suggests that in 2008/09p there were
11 fatalities, which is the lowest number over the 13 years. As noted earlier, around
13 fatalities per year are due to direct contact with electricity, and additionally an
average of around 4 fatalities per year are due to falls (both high and other types of
falls).
111
Yearly trends (HSE year):
12. For fatalities, a fluctuating picture is evident over the 13 year period 1996/97 to
2008/09p with a peak of 34 fatalities in 1996/97 and reaching a provisional low of 11
by 2008/09p (see Figure 5).
13. For non-fatal accidents, a clearer and encouraging steady decrease in accidents is
evident from 1996/97 to 2008/09p (see Figure 6).
HSE sectors (Field operations directorate, FOD):
14. From 1996/97 to 2008/09p, fatalities are highest for the Construction HSE sector (127
fatal accidents), with the Engineering and Utilities HSE sector recording the most non-
fatal accidents (40,235) (see Figure 7 and Figure 8).
Types of accident (Accident kind):
15. Over the full 13 year period 1996/97 to 2008/09p, contact with electricity or electrical
discharge is the type of accident most frequently causing fatalities (168). In terms of
non-fatal accidents, contact with electricity is relatively common (ranked fourth
highest, 7,464) but it is handling/sprains (27,249) and trips (20,065) that are far more
common (see Figure 9 and Figure 10).
16. Focusing only on more recent years (from 2001/02 to 2008/09p), a more detailed
classification of the data verifies that contact with electricity or electrical discharge is
the main cause of fatalities (88). For non-fatal accidents, contact with electricity or
electrical discharge is a common cause (ranked third highest, 3,887), but there are
significant numbers of non-fatal injuries from tripping over obstructions (5,507) and
lifting/putting down loads (3,902) (see Figure 11and Figure 12).
Job role (Occupation):
17. From 1996/97 to 2001/02, electric fitters (including electricians) reported the most
fatalities (38) followed by electrical engineers (15). Similarly, they both report the
greatest number of non-fatal injuries, with electric fitters (including electricians)
reporting 14,938 total non-fatal injuries and electrical engineers reporting 8,074 non-
fatal injuries (see Figure 13 and Figure 14).
18. From 2002/03 to 2008/09p, again electric fitters (including electricians) report the
most fatalities (44), as well as the highest total non-fatal injuries (10,933) (see Figure
15 and Figure 16).
Activity occurring at the time of accident (Work process):
19. From 1996/97 to 2000/01, electrical activities have reported the second highest
number of fatal accidents (13), with general maintenance activities being involved in
112
most fatalities (17). With non-fatal accidents, electrical activities report only the ninth
highest number of accidents (1,734), with the most accidents relating to on-site
transfer such as movement of persons or materials (7,898) and general handling
(7,345) (see Figure 17 and Figure 18).
20. From 2001/02 to 2008/09p, electrical activities by far report the highest number of
fatal accidents (56), and additionally report the highest number of non-fatal accidents
(8,965) (see Figure 19 and Figure 20).
Main object/movement involved in accidents (Agent):
21. From 1996/97 to 2000/01, unintentional contact with overhead lines as well as contact
with electricity/electrical discharge reported the first and second most fatal accidents
(20 and 19 respectively). However, for non-fatal accidents, the picture is quite
different with the moving of heavy weights or strains/sprains being involved in most
accidents (see Figure 21 and Figure 22).
22. From 2001/02 to 2008/09p, contact with overhead lines features as one of the most
common objects/movements involved in fatalities (20) along with other types of
electricity cable - including those trailing and buried in walls (20). It is this latter
category that also reports the most non-fatal accidents (5,936), with overhead lines not
appearing to be related to any significant number of non-fatal accidents (see Figure 23
and Figure 24).
Age:
23. For fatalities from 1996/97 to 2008/09p, those aged between 25 and 34 and 40 to 54
have recorded the most fatal accidents (between 32 and 34 accidents in each age
category) (see Figure 25).
24. For total non-fatal injuries from 1996/97 to 2008/09p, the number of accidents slowly
increases beyond the 16 to 19 age group (3,800) to reach a peak by 35 to 39 (10,886),
steadily decreasing thereafter. Within this, major injury levels appear to remain
relatively stable from 20 through to 54 (around 2000 accidents in each age grouping)
(see Figure 26).
‘ALL RELATED’ ACCIDENTS
25. 40% of all fatalities (1,201 deaths) over the 13 year period 1996/97 to 2008/09p,
across all industries may be potentially linked to ‘all related’ accidents (involving
either direct contact with electricity, or tenuously linked to electrical sources or
components) (see Table 25). However, due to the possible tenuous link, caution
should be exercised when using these figures.
26. Overall, this means in ‘all related’ accidents from 1996/97 to 2008/09p arising from
electrical based work and accidents indirectly related to electricity (where electricity
113
or electrical components feature in some way, although not necessarily causal in the
fatality), there has been an average of 92 fatalities per year. Provisional data suggest
that in 2008/09p there were 28 fatalities, which is the lowest number over the 13
years. As noted earlier, there is an average of 13 fatalities per year due to direct
contact with electricity, the same annual average number of accidents due to being
struck by moving, flying or falling objects, but less than the average number of 18
fatalities per year due to high falls (above 2 metres).
Yearly trends (HSE year):
27. For fatalities, a fluctuating picture is evident over the 13 year period 1996/97 to
2008/09p, with a peak in 2007/08 (136), although fatalities do dramatically fall the
following year in 2008/09p (provisionally 28) (see Figure 27).
28. For non-fatal accidents, there is evidence of total accidents remaining stable from
1996/97 to 2000/01. From 2001/02 to 2008/09p, the trend appears to show total
accidents gradually decreasing from 19,504 to 14,257 by 2008/09p (see Figure 28).
29. Overall, these findings indicate the success of efforts by HSE and industry to reduce
electricity related accidents.
HSE sectors (Field operations directorate, FOD):
30. From 1996/97 to 2008/09p, the Construction HSE sector reports the greatest number
of fatal accidents (427), double that of the next highest reporting sector, which is the
Agriculture and Wood HSE sector (205) (see Figure 29).
31. For total non-fatal accidents from 1996/97 to 2008/09p, the Engineering and Utilities
HSE sector reports the most accidents (57,653). However, the Construction HSE
sector reports the greatest number of major injury accidents (12,448) (see Figure 30).
Industry (SIC industry code):
32. From 1996/97 to 2008/09p, installation and fitting of electrical wiring reports the
fourth highest fatality numbers (52), with the greatest number of fatal accidents being
reported by the industry related to the construction of buildings and civil engineering
works (142) (see Figure 31).
33. For non-fatal injuries from 1996/97 to 2008/09p, installation and fitting of electrical
wiring reports the greatest number of total accidents (11,983), although there are other
industries related to the manufacture of various electrical components that also report
varying numbers of accidents (see Figure 32).
114
Types of accident (Accident kind):
34. Over the full 13 year period 1996/97 to 2008/09p, contact with electricity or electrical
discharge reports the third greatest number of fatal accidents (168), after high falls
(233) and being struck by objects (174). In terms of non-fatal accidents, the picture is
slightly different with contact with electricity only reporting the seventh highest
number of accidents (7,464), with most accidents due to handling/sprains (51,456)
(see Figure 33 and Figure 34).
35. Focusing only on more recent years (from 2001/02 to 2008/09p), contact with
electricity or electrical discharge reports the second highest number of fatal accidents
(88), with high falls (125) being the primary type of fatal accident. For non-fatal
injuries, contact with electricity does not feature as strongly (3,887 total non-fatal
accidents) compared to machinery, hit by objects and trips and slips (all above 10,000
accidents each) (see Figure 35 and Figure 36).
Job role (Occupation):
36. From 1996/97 to 2001/02, electric fitters (including electricians) report the greatest
number of fatal accidents (38) as well as the greatest number of total non-fatal
accidents (14,938). Electrical engineers rank eleventh in fatality numbers (15), but do
have the second highest number of non-fatal injuries (8,074) (see Figure 37 and Figure
38).
37. From 2002/03 to 2008/09p, electric fitters (including electricians) report the most fatal
accidents (44) as well as the greatest total number of non-fatal accidents (10,933) (see
Figure 39 and Figure 40).
38. Further analysis of the accidents only involving electric fitters (including electricians)
for the 13 year period 1996/97 to 2008/09p showed that fatal accidents are
predominantly related to contact with electricity/electrical discharge (31) or high falls
(20). Non-fatal injuries in this population are often handling and sprains (7,454) and
trips (5,908) (see Figure 41 and Figure 42).
39. These results suggest a need to target electric fitters (including electricians), focusing
on best practice when working in direct contact with electricity, working at height, and
handling loads.
Activity occurring at the time of accident (Work process):
40. From 1996/97 to 2000/01, electrical activities have reported relatively few fatal
accidents (13) compared to general maintenance activities (49), and on-site transfer of
people or materials (32) and loading/unloading (30). The non-fatal accident profile is
similar (see Figure 43 and Figure 44).
115
41. From 2001/02 to 2008/09p, electrical activities ranked third in terms of the highest
number of reported fatal accidents (56), with manufacturing production (79) and
machine maintenance (74) ranking higher. The non-fatal accident profile is similar
with electrical activities reporting 8,965 accidents, which is lower than manufacturing
production (26,316) and machine maintenance (12,250) (see Figure 45 and Figure 46).
Main object/movement involved in accidents (Agent):
42. From 1996/97 to 2000/01, electrical related objects/movements (i.e. unintentional
contact with overhead lines (20) and direct contact with electricity/electrical discharge
(19)) report the second and joint third highest fatal accident numbers respectively.
Falls off moveable ladders reports the highest number (21). For non-fatal accidents,
electrical objects/movements do not really feature as significantly (see Figure 47 and
Figure 48).
43. From 2001/02 to 2008/09p, the low significance of electricity objects/movements in
relation to fatal accidents is evident, with overhead power lines (20) and other
electricity cables - including those trailing and buried in walls (20) ranking low
compared to the involvement in fatal accidents of objects/movements such as fork lift
trucks (33) and moveable ladders (28). For non-fatal accidents, other electricity cables
report the fourth highest number of total accidents (5,936), with other materials and
machinery reporting the highest number (11,519) (see Figure 49 and Figure 50).
44. These results potentially indicate further consideration should be given to
interventions that do not merely focus on contact with electricity, but also working at
height (ladder use), and working around fork lift trucks and machinery.
Age:
45. For fatalities from 1996/97 to 2008/09p, the 40 to 44 age group and those 50 to 59
have reported the highest number of fatal accidents (above 137 fatalities in each age
category) (see Figure 51).
46. For total non-fatal injuries from 1996/97 to 2008/09p, the pattern of accidents
increases from 16 years of age (7,443) up to a peak by the 35 to 39 age group
(22,930), and then decreasing thereafter. Within this, major injury accident numbers
are relatively consistent (over 4,000) from the 20 to 24 age group through to the 55 to
59 age group (see Figure 52).
47. It should be noted that these figures do not necessarily indicate that certain age groups
are more vulnerable to accident (since figures presented are frequencies rather than
calculated rates).
116
Employment status:
48. From 1996/97 to 2008/09p, around three quarters of all fatalities over the 13 years
have involved those classified as ‘employees’ (924), with ‘self-employed’ fatalities
constituting around 21% of all fatalities (250) (see Figure 53).
49. Similarly to the fatalities profile, most non-fatal accidents from 1996/97 to 2008/09p
have involved ‘employees’ (in fact nearly all accidents, 180,899), with the ‘self-
employed’ being involved in a comparatively minimal number of total accidents
(4,195) (see Figure 54). However, this may be partly explained by under-reporting of
non-fatals in the self-employed.
50. It should be noted that these figures do not necessarily indicate that certain types of
employment are more vulnerable to accident (since figures presented are frequencies
rather than calculated rates).
Monthly pattern:
51. From 1996/97 to 2008/09p, accumulatively most fatalities have been reported for
August (130), with relatively high numbers (above 100 in each month) for January,
and June through to November (see Figure 55).
52. From 1996/97 to 2008/09p, accumulatively most non-fatal injuries have been reported
for January, June, July and September through to November (all around 16,000
accidents in each month). December reports the lowest number of total non-fatal
injuries (11,419) (see Figure 56).
53. These findings may provide some indication regarding the best time to launch media
campaigns or timely reminders throughout the year in order to reduce accident levels
further.
Types of injury:
54. From 1996/97 to 2008/09p, fatal accidents due to contact with electrical sources
(leading to loss of consciousness and shock, etc.) report the joint fourth highest fatal
accident numbers (145) (see Figure 57).
55. From 1996/97 to 2008/09p, non-fatal injuries caused by electricity are relatively low
(4,183 total non-fatal injury), compared to strains (53,554) and fractures (37,169) (see
Figure 58).
Region:
56. From 1996/97 to 2008/09p, the highest number of fatal accidents have been reported
by the ‘East and South East’ region (243), followed closely by the ‘Midlands’ (222), a
picture which is similar to the non-fatal injury profile whereby the ‘East and South
117
East’ (36,630) report the highest total accident level, followed by the ‘Midlands’
(35,191) (see Figure 59 and Figure 60).
57. At the local authority level from 1996/97 to 2008/09p, highest fatality numbers are
reported by Manchester (21), followed by Sandwell and Birmingham (both 16). The
non-fatal accident profile is similar, with Birmingham recording the highest total
accident number (3,736), followed by Leeds (3,005). Manchester also records the
fourth highest number of non-fatal accidents (2,275) (see Figure 61 and Figure 62).
58. With HSE insight into the resources available in different regions and cities, it may be
useful to compare any areas that report high accident levels with comparable regions
and cities that report lower levels. This exercise could yield further information into
best practice in certain areas that could be applied to other areas, particularly those
with high accident levels.
Objective 3: Produce a report that contains analyses of the electricity-related
accident data; identify the key issues; and identify key priority areas for
intervention.
59. This report directly addresses Objective 3.
60. The overall approach taken in this report is to use the RIDDOR accident data to
develop a profile of key electricity-related risks and thus help HSE develop prioritised
interventions supported by a preliminary evidence base.
61. It is recommended that the ‘direct contact’ and ‘electrical based’ data sets are primarily
used for future HSE policy development work.
118
7. RECOMMENDATIONS
The purpose of this study was to provide a preliminary evidence base for developing policy, not
to develop that policy. Nevertheless, outline recommendations have emerged from the study,
and it is suggested that the following areas be addressed in order to reduce the risks associated
with electricity-related accidents.
7.1 GENERAL RECOMMENDATIONS
Based on the work undertaken in this project, the following general recommendations are
presented as a means of improving health and safety in relation to electricity-related accidents:
1. This report is one source of evidence to supplement existing knowledge and expertise
in the HSE. Its findings should be considered in relation to existing knowledge and
guidance around some of the identified risk areas in this report.
2. Some caution should be exercised when interpreting the figures for the ‘all related’
data set, as this data set does contain a number of accidents that are only indirectly
related to electricity. It is therefore recommended that any HSE policy development
work is primarily based upon the ‘direct contact’ and ‘electrical related’ data sets, as
these contain accidents assigned electricity-related RIDDOR codes only.
3. It may be that further work is needed, such as a detailed analysis of notifier comments
and investigation reports, and workshops to drill further into the potential reasons
behind the statistics. For individuals whose roles involve working with or around
electricity, what might they perceive the risk issues to be? What might motivate them
to work more safely? Developing the evidence base will provide HSE with the means
to develop prioritised interventions, suited to the target population, and supported by a
full audit trail.
4. Whilst accidents resulting from direct contact with electricity give rise to significant
cost impact to Great Britain, they are not always the most frequently occurring. Slips,
trips, low and high falls, and handling/sprain injuries also feature prominently. The
risks associated with these accidents should therefore be addressed in conjunction with
those risks associated with contact with electricity.
5. Demographic differences in the cities and regions of GB may need to be studied more
closely given the differential levels of electricity-related accidents suggested from the
results of this study. It may be useful to compare regions of similar size, but with a
big difference in accident levels, to understand what practices are being carried out
that could be affecting accident levels. Distilling best practice could then be
transferred to other areas of the country.

APPENDIX 1 CREATION OF THE ELECTRICITY DATA SET
A1.1 INTRODUCTION
This chapter addresses Objective 1, which is to:
Develop an electricity-related accident data set from ‘supply to switch’ to provide a
baseline for measuring improvements across a range of industry sectors.
The main source of data is the RIDDOR accident data as provided by HSE to GL Noble Denton
under its confidential support arrangements. The analysis and results are show in Chapters 3, 4
and 5.
In this chapter, the RIDDOR accident reporting system is introduced, followed by a description
of how the RIDDOR data is incorporated within the RIDDOR Data Tool developed by GL
Noble Denton. The definitions used to develop the electricity-related accident data set are
described along with the validation checks undertaken on the data.
In considering the analyses of the RIDDOR data it is important to appreciate the uncertainties
associated with that data, this is because RIDDOR reports are made by people from a variety of
backgrounds, some of whom may have had either very specific health and safety training or
little or no health and safety training.
A1.2 RIDDOR ACCIDENT REPORTING
Reporting of the fatal, major or minor (over three days away from work) injury accidents to
workers associated with workplace activities is a statutory requirement of RIDDOR2. This
chapter provides a brief overview of the RIDDOR data as collected by HSE and subsequently
processed and analysed by GL Noble Denton. Detailed information is provided in References
2, 3 and 4.
In the period 1996/7 to 2000/01, RIDDOR forms, once completed, were sent to the local HSE
offices, where the information on them was coded with reference to HSE guidance5
on coding,
and entered into the central HSE FOCUS database by trained clerical staff. As of April 2001, a
central Incident Contact Centre (ICC) was established where dedicated staff deal with hard
copy, web and telephone notifications, as well as coding and entry of all RIDDOR report forms.
The fields available for analysis are summarised in Table 61. Those fields that have changed
with the introduction of the ICC system are denoted in bold. Those fields marked with an
asterisk in Table 61 were not completed in the FOCUS database when the reports were received
from the local authority enforced sectors in the period 1996/97 to 2000/01 as they ran a different
coding scheme. In April 2002, the Standard Occupation Classification (SOC 2000) was
adopted. For the 2002/03 data and beyond, the occupations of those injured at work were
recorded using the SOC 2000 system.
At the 1 April 2001 juncture when the ICC system was activated, a new scheme for coding
accident agents and work processes was also introduced and the categorisation of accident kinds
was modified slightly. It is understood there is no clear mapping between agents and work
121
processes for the pre- and post-ICC schemes and therefore the data sets are presented separately
throughout this report. Although accident kinds, ‘high fall, ‘low fall’ and ‘fall’ remain, the
guidance on coding falls has apparently been clarified so that a fall initiated by a ‘trip’ (e.g.
when getting out of a vehicle or on stairs) is now coded as a ‘slip or trip’ as opposed to a fall.
As such, it may be anticipated that the number of recorded falls in 2001/2 would reduce even if
the control of risks did not alter. Caution must therefore be exercised in interpreting trends and
changes from 1996/7-2000/01 to 2001/02-2008/09p in terms of accident numbers and rates.

A1.3 GL NOBLE DENTON RIDDOR DATA TOOL
Fatal, major and over 3-day injury accident records from FOCUS were supplied to GL Noble
Denton in separate electronic files for each of the 13 years from 1996/97 to 2008/09p, together
with ‘look-up’ tables cross-referencing the FOCUS codes to short and long descriptions as
contained in the HSE coding systems.
The RIDDOR data as supplied by HSE were processed by GL Noble Denton using the
following steps in accordance with Reference 3:
The raw accident data and updated look-up tables as received from HSE were
imported into a Microsoft Access database.
The data were validated and any anomalies were resolved in conjunction with HSE
statisticians.
The GL Noble Denton RIDDOR Data Tool was updated to include all accidents
notified between 1996/97 and 2008/09p.
Analyses of the accident data were carried out using Excel spreadsheet Pivot Tables
and Charts contained in the RIDDOR Data Tool.
In updating the database and Data Tool, reference was made to the HSE manual6
covering the
new accident kind, agent and work process codings.
Figure 63 shows the layout of the GL Noble Denton RIDDOR database. There are three main
tables in the database, containing the information on:
Accidents/Injuries
Investigations
Reports
The primary table used for this study is the Accidents/Injuries table. The data contained in this
table are summarised in Table 61. The database tables contain the numerical FOCUS codes
rather than the text descriptions. The associated look-up tables shown in Figure 63 provide
access to the text descriptions required for meaningful analyses.
It is important to note that inv_no (investigation number) is the field linking the principal tables.
Furthermore, the term ‘event’ is misleading in that each person injured constitutes an ‘event’
even when there are multiple injuries resulting from an accident.

In addition to the RIDDOR codes, the following narratives are available for analysis:
Investigation summary reports – These are available for all years between 1996/97
and 2008/09p.
Notifier comments - Summaries provided by the person notifying the accident. These
are only available from 2001/02 onwards.
124
A1.4 DEFINITION OF THE ELECTRICITY DATA SET
The full RIDDOR database contains over 1.9 million accident records for the period 1996/97 to
2008/09p. In order to carry out a meaningful analysis of the electricity-related accidents, all of
the relevant accident data in the RIDDOR database needs to be collected together. As there
may be electricity-related accidents that were not coded as relating to electricity, the following
two-prong approach was used to identify these incidents:
Identify all those accidents with electricity-related RIDDOR codes by searching for
one or more of the codings for industries, accident kinds, occupations, work processes,
and agents that correspond to those identified for the electricity-related accidents.
Identify those accidents where either the notifier comment or the investigation
summary report contains a term (or ‘keyword’) relating to electricity.
The accident data identified in the two separate approaches was initially combined into one data
set, which encompassed all accidents related to electricity. Two further subsidiary data sets
were also created for more focused analysis. In total three data sets were created and analysed
in this report, as follows:
Data set 1: ‘Direct contact’ with electricity – this data set is defined purely by the
RIDDOR accident kind categories ‘Electricity’ and ‘Volt’ (i.e. it only includes
accidents reported as being either an ‘Electricity’ or ‘Volt’ accident type).
Data set 2: ‘Electrical based’ (including ‘direct contact’) – this larger data set
contains the ‘direct contact’ accidents described above, as well as accidents reported
under other electricity-related RIDDOR categories (e.g. industries such as electricity
production, installation of wiring/fitting, manufacturing of electrical appliances;
occupations such as electrical engineers, electroplaters, etc.). For a full list of the
RIDDOR categories under this definition, please refer to Table 62 to Table 66 in this
appendix.
Data set 3: ‘All related’ accidents (including ‘electrical based’) – this is the full
data set (as described in Chapter 5), containing the ‘electrical based’ accidents
described above (i.e. all accidents assigned an electricity-related RIDDOR code) and
accidents brought in because their associated accident narrative (i.e. the notifier
comment or investigation report) contains an electricity related keyword (e.g. ‘spark’,
‘plug’, ‘socket’, etc.). For a full list of the keywords used under this definition, please
refer to Table 67 in this appendix.
In order to validate the main electricity data set (termed ‘all related’) and ensure the appropriate
accident records were included, a number of measures were taken. These included:
Conducting a visual check on the data and graphs to assess whether the trends being
illustrated were as expected. For example, initially, ‘distribution networks’ was one of
the keywords used to build up the ‘all related’ electricity data set. However, further
125
investigation revealed there to be a significant number of accidents involving postal
workers (mail collection, delivery and sorting). Subsequently, ‘distribution network’
was deselected from the data set definition.
Conducting a check on a sample of the notifier comments and investigation reports to
ensure that electricity-related accidents were being included in the ‘all related’ data
set. This also served the purpose of identifying potential keywords to be included in
the data set definition.
A1.4.1 Identifying accidents with electricity-related RIDDOR codes
Accidents with electricity-related RIDDOR codes were identified by searching the RIDDOR
fields: industries, accident kinds, occupations, work processes and agents. The individual codes
used to select the accident records for inclusion in the electricity data sets (as agreed with HSE)
are provided in Table 62 to Table 66. Each of these codes has a marker against it in the
RIDDOR accident database indicating that it is part of the electricity data sets. A query is used
within the database to select only those accident records where one or more of the codes in
Table 62 to Table 66 are present and these accidents are assigned an electricity ‘switch’.

A1.4.2 Identifying accidents with electricity-related RIDDOR keywords in their narratives
The list of keywords used to search within the notifier comments and investigation reports to
identify the electricity-related accidents are given in Table 67. The asterisk in the keywords
indicates its use as a ‘wildcard’. Thus, ‘cabl*’ indicates that the search will not only identify the
word ‘cable’ but also related words with the same prefix such as ‘cables’ and ‘cabling’.
Similarly, fuse* will detect related words such as ‘fuses’, ‘fuse-box’ and ‘fusing’. The
underscore before ‘amp’ and ‘arc*’ ensures that the search only brings up records made up of
the actual word. For instance, ‘_amp’ does not produce words such as lamp or clamp which
contain the letters ‘amp’.

Identifying the incidence of electricity-related accidents in Great Britain An update (1996/97 to 2008/09p)
This report analyses RIDDOR based electricity-related accidents covering all industries and is intended to be an update (and standalone report) to the previous HSE research report ‘Identifying the incidence of electricity-related accidents in Great Britain’.
Using certain selection criteria, the full RIDDOR database from 1996/97 to 2008/09p was searched to identify three categories of electricity accident:
a) ‘direct contact’ with electricity; b) ‘electrical based’ accidents; and c) ‘all related’ accidents.
Analysis was carried out using RIDDOR fields such as ‘HSE year’, ‘work process’ and ‘agent’. A number of findings were revealed, including electrical fitters (including electricians) reporting the greatest number of fatalities and non-fatal injuries, with many of the accidents related to contact with electricity (or electrical discharge). However, a number of other accidents were not related to direct contact with electricity, such as handling strains/sprains and high falls. It is proposed that the results of this report constitute an updated evidence base indicating possible priority areas for intervention by the HSE.
This report and the work it describes were funded by the Health and Safety Executive (HSE). Its contents, including any opinions and/or conclusions expressed, are those of the authors alone and do not necessarily reflect HSE policy.
