Incident
Investigation -- Tips, Techniques & Trivia
This week I am in Regina presenting at the Saskatchewan Safety
Council’s 34th Annual Industrial Safety Seminar, and next
week I’ll be delivering training in Edmonton.
In this issue I’m concluding the series on investigation
biases.

Investigation

Judging
Outcome vs. Behaviours Bias
We’ve
all seen hockey players take a dive and stay down on the ice after
being hit in order to try and get the referee to call a penalty.
They are hoping the referee sees what is an apparent bad outcome,
a potential injury; and makes the link that there must have been
some bad behaviour to cause this, and a penalty is called.
We often do the same thing in our investigations and the more
serious the incident the more likely we are to look for “bad
behaviour.” However, we should not consider the incident
outcome in our investigation. After all, the worker did not know
what the outcome would be, and therefore did not use this information
as part of his decision making.
For
example, a worker uses a forklift tagged out of service due to
faulty brakes to move a pallet just a few feet. He may have thought
that he could do this safely if he took his time. He didn’t
expect a pedestrian to step in front of him and that this would
result in a serious injury.
The
behaviour we should focus on is the use of tagged out equipment,
not the injury to the pedestrian. We tend to turn a blind eye
to rule violations until someone gets hurt, or the outcome is
significant -- then it becomes a serious matter! Management’s
reaction to the rule violation should be the same regardless of
the outcome.
What if (counterfactual thinking)
Bias
In every accident scenario there are always things that if changed
would have prevented the accident. For example, a female coworker
in a hurry to deliver a bulky file to another department falls
on the stairs and is injured.
The “what if” questioning takes over. What if she
had waited for the elevator? What if she had put the file in a
briefcase so she could use the handrail? What if she had been
wearing sensible shoes (always the male question)?
If
there are things that she could have done differently, then we
tend to blame her for the accident even if the other possibilities
are not practical. It’s not a big leap from “well
if you could have done something different, then you should have
done something different!”
This
thinking leads us to faulty conclusions and only focuses on what
the employee didn’t do, not on what they may have done properly.
This oversimplifies the situation and accidents are never that
simple.
