Investigating a mishap scene could expose you to
health hazards such as soot, sharp metal, toxic
chemicals, or asbestos fibers in torn lagging. In such
cases, you need to wear at least the following protective
Adequate respiratory protection
Safety glasses and goggles
If a respirator is necessary, your respiratory
protection officer or shore Respiratory Protection
Program manager can help you get fit-tested and ensure
you receive the required medical screening.
A mishap has occurred! The worst that could
happen has happened! What are your priorities? There
is no question about the first priority at a mishap
sitesave lives and prevent more injury and property
loss. Aboard ship, damage control takes priority over
preserving the scene of the mishap for investigators.
Begin your investigation as soon as possible after
the mishap. The sooner you begin, the better your
investigation will be. Witnesses will be present. You can
gather more accurate facts because the damage and
materials involved will be in the same relative position
as when the mishap occurred.
The mishap investigator is seldom the first to arrive
at the scene of a mishap. An activity with a pre-mishap
plan will have a supervisor on the scene who knows how
to protect the site, detain witnesses, and provide
observations. Protecting and preserving the mishap site
is important. However, it may be necessary to disturb
the scene for damage control purposes.
Your first overall observation and analysis on
arrival at the scene is critical. Slow your approach to the
scene so that you can observe the overall big picture.
Start your investigation the minute you arrive, but
dont hinder damage control or first-aid efforts. Dont
become part of the mishap! Once people have calmed
down, victims have been removed, and the area is safe,
your priorities are as follows:
Preserve the evidence
Protect the mishap site
Secure the evidence
You will have little time to plan your investigation.
Always be ready to begin collecting facts and evaluating
the situation with little prior notification.
Mishaps gather crowds! People forget their work
and begin running in all directions as they rush in for a
look. Too often, many more people arrive on the scene
than need to be there. Preserving evidence and
controlling activities under these conditions is almost
hopeless. Evidence gets washed away, trampled on,
thrown over the side, picked up as a souvenir, or scooped
up in initial clean-up efforts.
When a mishap occurs, especially aboard ship,
everyones first thought is to get the site back to normal.
That must be discouraged if it doesnt impact on
operational readiness. Anything that can be left in place
should not be touched.
As a safety supervisor, you may be a key player in
preserving evidence until a mishap investigation board
arrives. Take the following steps (which should be
included in your pre-mishap plan) to preserve evidence:
Cord off or secure the mishap scene. Post a guard
if you must!
Get a photographer on the scene as soon as
possible to take photographstakes lots of
photos of everything. Use a video camera, if
available, as well.
Cover the scene with a tarp if the scene is
outdoors or if the scene may be disturbing to
Prevent witnesses from leaving the area. Keep
them from conversing with each other, if
possible. Get their names and a phone number
