Managing Asbestos – Part Two
Before considering the different work types, we need
to firstly define work with asbestos.
‘Work with asbestos’ includes:
• work which removes, repairs or disturbs asbestos;
• work which is ancillary to such work (ancillary
work);
• supervising the work referred to in the two bullet
points above (supervisory work).

Managing Asbestos – Part Two
There are two distinct work types undertaken with
asbestos, these are best known as:
• Licensable Work
• Non-Licensable Work (Inc Notifiable Non-
Licensable Work)
ATL 2018 ©WWW.UKATA.ORG.UK | INFO@UKATA.ORG.UK | 01246 824 437
6
Managing Asbestos – Part Two
Licensable work
That is work:
• where worker exposure to asbestos is not sporadic
and of low intensity or
• where the risk assessment cannot clearly
demonstrate that the control limit (0.1 f/cm3
airborne fibres averaged over a four-hour period)
will not be exceeded; or
ATL 2018 ©WWW.UKATA.ORG.UK | INFO@UKATA.ORG.UK | 01246 824 437
7
Managing Asbestos – Part Two
Licensable work
• on asbestos coating (surface coatings which
contain asbestos for fire protection, heat insulation
or sound insulation but not including textured
decorative coatings); or
• on asbestos insulation or AIB where the risk
assessment demonstrates that the work is not
sporadic and of low intensity, the control limit will
be exceeded and it is not short duration work.

Materials in which the asbestos fibres are firmly
linked in a matrix
• asbestos cement;

Managing Asbestos – Part Two
With the introduction of the CAR 2012, two further
definitions have been given to determine if NNLW
applies.
Maintenance Work – this is defined as drilling holes
or painting ACM’s, it also includes the removal of
ACM’s where the removal work is ancillary to the
main task.
Removal – this is defined as refurbishment or
demolition works where the ACM’s have to be
removed.

Regulation 10: Training of Employees
There are three main types of information, instruction
and training.
These are:
(a) Asbestos awareness training.
(b) Training for non-licensable asbestos work.
(c) Training for licensable work with asbestos.
ATL 2018 ©WWW.UKATA.ORG.UK | INFO@UKATA.ORG.UK | 01246 824 437
13
Managing Asbestos – Part Two
For those undertaking NLW,
the guidance generally to
follow is HSG 210.
There are two main sections:
EM – Equipment and Method
A Sheets – Various tasks
ATL 2018 ©WWW.UKATA.ORG.UK | INFO@UKATA.ORG.UK | 01246 824 437
14
Managing Asbestos – Part Two
For licensable works
being undertaken the
guidance document is
HSG 247
ATL 2018 ©WWW.UKATA.ORG.UK | INFO@UKATA.ORG.UK | 01246 824 437
15
Managing Asbestos – Part Two
There are four practices that require a licence issued
by the HSE:
• Asbestos Removal, where regulation 3 (2) cannot
be satisfied
• The construction of a Scaffold where access is
required to remove licensable asbestos materials,
where it is foreseeable that asbestos will be
disturbed (Reg 3(2).
• Supervisory Licence holder
• A company maintaining NPUs and Vac’s
ATL 2018 ©WWW.UKATA.ORG.UK | INFO@UKATA.ORG.UK | 01246 824 437

Managing Asbestos – Part Two
Regulation 9: Notification of work
If a contractor undertakes licensable work they have
to notify the appropriate enforcing authority with
details of the proposed work.
This gives the enforcing Authority the opportunity to
assess the proposals for carrying out work with the
asbestos containing materials and to inspect the site
either before or during the work.
ATL 2018 ©WWW.UKATA.ORG.UK | INFO@UKATA.ORG.UK | 01246 824 437
17
Managing Asbestos – Part Two
They will normally be required to notify the relevant
enforcing authority office 14 days before any work
begins, but the enforcing authority may allow a
shorter period, e.g. in an emergency where there is a
serious risk to the health and safety of any person.
This shorter period is known as a ‘waiver’ or
dispensation.
*The waiver.....it has become increasingly more
difficult to successfully request a waiver, the waiver
must include a formal request from the client as well
as the contractor.

Plan of Work (POW)
In accordance with CAR 2012, Regulation 6 & 7, the
contractor will be required to assess and produce a
suitable and sufficient POW (aka Method Statement).
This MUST be prepared before the work is notified to
the Enforcing Authority
This needs to be job and site specific.
ATL 2018 ©WWW.UKATA.ORG.UK | INFO@UKATA.ORG.UK | 01246 824 437
28
Managing Asbestos – Part Two
The plan of work must include the following
information:
• the nature and probable duration of the work;
• the number of people involved in the work;
• the address and location where the work is to be carried out;
• the methods to be used to prevent or reduce exposure to asbestos,
eg prevention and control measures, arrangements for keeping
premises and plant clean and arrangements for the handling and
disposal of asbestos waste;
• the type of equipment, including PPE and RPE, used for:
– protecting and decontaminating those carrying out the work;
– protecting other people present at or near the worksite.

Safe Working Methods (Control Measures)
There are a number of methods which can be used
when removing asbestos, all of which should ensure
that fibre release is minimised.
Methods available:
• Wrap and cut
• Spray wetting
• Shadow vacuuming
• Wet injection

Enclosures
HSE Guidance note for enclosure construction
provided for work with asbestos – HSG 247.
Enclosures may either make use of the fabric of the
building or may be self supporting built around the
work area.
The enclosure should be constructed with the view to
avoid the spread of asbestos from the work area.

The Role of the Analyst
After asbestos removal works have
been carried out, the enclosure
should be tested in accordance with
HSG 248 (The Analysts Guide), CAR
2012, L143
CAR states that the independent
laboratory carrying out the clearance
test should conform to ISO 17025
It is recommended that the Client
appoints the Analyst

Types of air sampling
• Background Monitoring (BM)– before the
work begins
• Leakage Monitoring (LM) – during work,
outside
• Personal Monitoring (PM)– inside while
carrying out the work
• Clearance Test (CT) – after removal
works, pre de-tenting
• Reassurance Monitoring (RM) – after
enclosure removed

Certificate of Reoccupation (CORO)
There are four stages to the site
certification for reoccupation procedure:
• Stage 1: Preliminary check of site condition
and job completeness;
• Stage 2: A thorough visual inspection inside
the enclosure/work area;
• Stage 3: Air monitoring;
• Stage 4: Final assessment post-
enclosure/work area dismantling.
