They explain everything
Health and Safety?
Let’s look at the LARGE scale …
Annual Reports
Lost Time Injury Frequency Rates(LTIFR)
Lost Man Hours
Number of Injuries
Disease Rates
ISO Compliance
Insurance Costs
Legal Costs
Fines
Different systems
Health and Safety
Plant damage and reliability
Production and efficiency
Environmental Damage
Are they really different?
Common explanation?
What about the small scale?Small

Job Safety Analysis
Standard Operating Procedures
Applied Standards
Permits to work
Personal Experience
Common Sense
These views are not compatible
Workers don’t use LTIFR
Workers don’t useinsurance costs
Companies don’t usethe number of JSA’s
Companies don’t usethe number of standards

Worker
Employee Health and Safety

Environmental Damage
We need a single model
One that explains everything
Time for some research
Occams’s Razor
“Entia non sunt multiplicanda
praeter necessitatem.“
Entities should not be multiplied
beyond necessity.”
As few assumptions as possible,but as many as you need.
NOT“The simplest explanation
is the best”
Every accident
One common factor
An exchange of energy must occur
Energy causes damage
Energy?
Muscular
Gravitational
Electrical
Thermal
Chemical
Fire and Explosion
Mechanical
Noise and Vibration
Kinetic
Biological
Pressure
Radioactive
Psycho-social
Energy
Energy is Good
Energy is Bad
Lose control
Bad Things
The consequences are different
Injuries and disease
Damage to plant and equipment
Production loses
Fines and legal costs
Environmental damage
The mechanisms are the same
Energy Causes Damage
Eliminate the Hazard
Remove the Target
Substitute
Shield the Hazard
Limit Exposure
Increase Space / Time
Protect the Target
Exceeds Hierarchy of Control
Complies with standards
More Super Strings?
Things happen over time
Time Sequence Model
The
Consequences

What
happened?
The
Circumstances
time
What allowed it
to happen?
Very specific event
What
happened?
time
The point in time you lose control
Example …
Single cause?
“The Accident”
Multiple Causes
Fault Trees

Great for risk assessments
Great for investigations

More Super Strings?
Culture?
What determines theculture of a company?
Culture is determined bywhat is important
What’s importantgets attention
Key Performance Indictors
The order is critical!
Change the KPI’s
=
Change the culture
Change the KPI’s
=
Change the behaviour
Are you getting what you want?
If not, change the KPI’s
Can’t measure it,
Can’t manage it.
Can you measure culture?
Values Driven Safety
Find out what you want
Do a cultural survey ...
Check the results
It’s not an accurate tool
It’s a good barometer
Are there more Super Strings?
The challenge ...
We need a new system
Focus on the real causes
As few assumptions as possible,but as many as you need.
Measure the right things
Eliminate assumptions
Get real results
Make a difference!
