Quotable Quote
"A health & safety problem can be described by
statistics but cannot be understood by
statistics. It can only be understood by knowing and
feeling the pain, anguish, and
depression and shattered hopes of the victim and of
wives, husbands, parents children,
grandparents and friends, and the hope, struggle and
triumph of recovery and
rehabilitation in a world often unsympathetic,
ignorant, unfriendly and unsupportive, only
those with close experience of severe permanent
disability have this understanding"
Personal damage not accidents
You will notice throughout this discussion paper I
refer to personal damage and do not
refer to accidents. The term accident perpetuates
the belief that the damaging event could
not be predicted and was largely the result of
personal failure by the damaged individual.
While such beliefs are emotionally appealing they
are unhelpful and they cloud objective
analysis of the damaging event.

Central theme of this discussion paper
My personal experience in safety
roles in Australian industry tells me it is difficult
to make meaningful progress in
safety when one has a focus principally on Lost
Time Injuries.
This statement may upset those with a traditional
approach to safety, given the enormous
cost of occupational personal damage in Australia it
would be difficult for the
traditionalists to point to a solid record of
success with their approach .The traditional
approach to safety management in Australia often has
a poor record of basing actions on
solid facts.
During my late teenage years in the Australian
Regular Army they taught me not to
wander onto a minefield without knowing where the
mines were located. Some safety
personnel and line managers frequently enter the
safety minefield unaware of where the
mines really are.
I am reminded of the annual report for one company
that proudly proclaimed a significant
decrease in L.T.I.F.R. while at the same time
neglecting to mention the fact that there had
been 4 fatalities in the company during the
year!
The Lost Time Injury Frequency Rate impedes progress
in safety
The Lost Time Injury Frequency Rate is the principal
measure of safety performance in
many companies in Australia. The definition of
L.T.I.F.R. is the number of Lost Time
Injuries multiplied by 1 million divided by the
number of manhours worked in the
reporting period
A Lost Time Injury is a work injury or disease where
the injured party has at least 1
complete day or shift off work. Note that a fatality
and a cut where a person has 1
complete day off work count the same in Lost Time
Injury terms.
The following are my reasons why the L.T.I.F.R.
impedes progress in safety.
1 The L.T.I.F.R. is subject to
manipulation
Some safety people cheat like hell with their
L.T.I.F.R. statistics encouraged by managers
with an eye to keep their key performance indicators
looking good. The more the
pressure to keep K.P.I.'s looking good the more
creative the accounting. If the same
ingenuity was displayed in preventing incidents as
is displayed in cooking the books we
would be in great shape. All this makes
inter-company comparisons of L.T.I.F.R.
statistics less in value.
I am reminded of one mine I used to deal with who
drove L.T.I.F.R. down so they won
the inter-mine (out of 7 mines) safety award yet had
significantly higher workers
compensation costs per employee and a number of
compensation days off cases that
never made it onto the L.T.I.F.R. statistics (the
vagueness of the Australian Standard for
Recording and Measuring Work Injury Experience was
exploited, very easy to do,
particularly for back injuries).
Then there was the mine that won a prestigious
Queensland government mining industry
safety award and a taxi full of "walking wounded"
turned up just as the award for no lost
time injuries for the year was being presented. The
award was subsequently withdrawn.
2 Ponderous
deliberations
Safety people spend inordinate periods of time
obtaining rulings on what to count and
how to count it from bodies such as the Australian
Standards Association. Often answers
obtained are imprecise and the decisions are left to
personal opinion. One is reminded of
a sporting analogy where it is more important to
play the game than keep the score.
3 Measuring
failure
Most measures in management are of achievements
rather than failures such as the
number of Lost Time Accidents. There is a ground
swell in the safety movement talking
about Positive Performance Measures in safety (refer
to the National Occupational Health
& Safety Commission and the Minerals Council of
Australia web-sites for a discussion
on this topic) It is relatively simple to develop
measures of what you are doing right in
safety as opposed to using outcome measures such as
L.T.I.F.R. Positive performance
measures can be used to gauge the success of your
safety actions.
4 Great L.T.I.F.R., pity about the
fatalities
I have personal experience with a company that
aggressively drove down L.T.I.F.R. to a
fraction of its original rate in a space of about 2
years yet killed 11 people in one incident.
5 What does it
mean
The Lost Time Injury Frequency Rate predominates
discussions about safety
performance. How can a company be proud of a
decrease of L.T.I.F.R. from 60 to 10 if
there have been 2 fatalities and 1 case of
paraplegia amongst the lost time injuries? The
L.T.I.F.R. trivialises serious personal damage and
is a totally inappropriate measure of
safety performance.
6 Accident Ratio Studies Mis-direct
Efforts
My grandmother used to say "Look after the pence and
the pounds will look after
themselves" In the world of traditional safety there
seems to be similar thinking that if
you prevent minor damage you will automatically
prevent major damage. Accident ratio
studies (insisting on set ratios between near
misses, minor accidents and serious
accidents) are prominent and accepted unthinkingly.
The much-quoted "Iceberg Theory"
in relation to safety does not stand up to scrutiny
in the real world! The "Iceberg Theory"
is fine if used for statistical description but it
cannot be relied upon for statistical
inference.
The result of the "Iceberg Theory" focus is a
furious effort to eliminate lost time injuries
in the belief that all major incidents will be
eliminated in the process. Certainly there are
minor incidents that have the potential to result in
more extensive damage( and we should
learn from them) ,but personal experience tells me
the majority of minor damage
incidents do not have this potential. It is a matter
of looking at the energy that was
available to be exchanged in the incident. The
common cold cannot develop into cancer,
similarly many minor injuries will never develop
into serious personal damage.
The concept that preventing the minor incidents will
automatically prevent the major
ones seems to me to be fundamentally
flawed.
All organisations have limited resources to devote
to safety, it seems more efficient to
prevent one incident resulting in paraplegia than to
prevent 20 incidents where people
have a couple of days off work (some will say this
comment is heresy)
Somewhere in the push to reduce L.T.I's, reduce the
L.T.I.F.R. and consequently achieve
good ratings in safety programme audits the focus on
serious personal damage tends to be
lost.
Reducing the L.T.I.F.R. is as much about introducing
rehabilitation programmes and
making the place an enjoyable place to work as it is
about reduction of personal damage
Recommendations
In my view a concentration on the Lost Time Injury
Frequency Rate has hijacked the
Australian safety profession for far too long. The
following are my recommendations for
action.
Use positive performance
measures
Incorporating positive performance measures into
regular audits is a fertile area for
measuring your success in safety. Many approaches to
safety auditing are available. One
can use one of the commercially available audit
approaches (N.S.C.A.5 Star, N.O.S.A.5
Star, D.N.V., Safety Map, I.S.R.S. etc.) An
alternate approach is to decide on internal
standards of OHS excellence specific to the
enterprise, develop auditing guidelines based
on the standards, train your own personnel to
participate in audit teams led by a senior
manager and carryout the audits yourself with the
assistance of an experienced outside
OHS auditor. I would argue the latter approach
builds more involvement and learning
into the auditing process and if properly structured
is more targeted to the real needs of
the organisation (plus it lessens the auditing fees)
Having a comprehensive range of
safety positive performance indicatiors built into
the performance appraisal process tends
to get people's attention focused on
safety
Classifying Personal
Damage
A method of classifying personal damage that seems
appropriate is the following-
CLASS 1-Damage that permanently alters a persons
life e.g. death, paraplegia,
amputation of a leg, severe psychological
damage.
CLASS 2- Damage that temporarily alters a persons
life e.g. fractured leg that repairs
with no lasting impediment ,deep laceration that has
no underlying tissue damage and
repairs without significant scarring
CLASS 3 Inconveniences a person's life
Focus on Class 1
Damage
The report of the Industry Commission 1995 indicates
that safety in Australia is
fundamentally a class 1 problem (87% of occurrences
were class 2 with18% of cost,13%
of occurrences were class 1 with 82%
of cost)
This report further strengthens the argument that
instead of concentrating on reducing
L.T.I.F.R. we should be focusing on Class 1 damage
reduction. There is no shortage of
computerised accident data systems in Australian
industry that focus on Lost Time
Injuries and completely ignore obtaining the more
important
industry experience
of
Class 1
damage. The ideal would be to have an Australia-wide system
of collecting class
1 damage information
Class 1 incidents have more energy available to be
exchanged than the usual Lost Time
Injury and thus require a different preventative
approach.
Methods of class 1 damage reduction can be found in
the paper" Change For The Future-
Not Blame For The Past" by
G.L.McDonald.
The message about class 1 damage reduction has yet
to sink in to many people's minds,
many in the mining industry are attuned to this
approach.
A new paradigm
required
Stepping out of the Lost Time Accident paradigm and
into the Class 1Damage paradigm
requires re-focusing our efforts.
Class 1 prediction requires
A Improved damaging occurrence investigation than is
the norm in industry (some
training in using a specific incident investigation
model is required for incident
investigation teams)
B External (industry preferably) class 1 taxonomy (a
taxonomy can be loosely described
as a collection of like) The Australian mining
industry has made moves towards having a
standardised industry accident investigation and
recording system, there is a real need for
other industries to adopt this
approach.
C Internal taxonomy (class 2 & class 3 damage)
Most organisations, thankfully, do not
have a rich data base of class 1 damage that can be
used for prediction.
D Workforce information (eg. critical incident
recall-Refer to the paper "Practical
Implementation of the Critical Incident Recall
Technique" by this author)
E Scientific knowledge applied to safety issues eg.
required co-efficients of traction to
prevent slips & falls
Using the above approach is not easy but it means
your safety programme is based on
solid facts not the latest
safety fad drummed up by those with vested interests.
Further discussion on the L.T.I.F.R. can be found in
the paper "Focus-Don't Fiddle (The
Obscenity of the L.T.I.F.R) Geoff McDonald, Coal
Industry Safety Conference1995,Qld.
Mining Council.
The more I think about it the more I am inclined to
the view of Geoff McDonald that
there is no better basis for your personal damage
reduction efforts than well researched
data on class 1 damage.
Conclusion
As a nation we do not investigate incidents well, we
do not collect the information well,
we do not analyse it well and we do not learn from
it well (facts again). My belief is
that
the focus on Lost Time Injuries and L.T.I.F.R. has
impeded progress long enough, we
need to shift our focus to class 1 damage and the
use of positive performance indicators.
By now you will realise I take a different view on
OHS to many people practicing in the
field. Please refer to my paper "What Makes a Safety
Programme Fly-Mark 2" for a
reasonably conventional approach to managing safety
problems.
I will be disappointed if I do not promote some
debate with the above. I welcome debate
from people who have facts to
back up their argument
Have a safe day
