4. Isolation Procedures
When someone is going to work on hydraulic, fuel,
water and electrical systems:
The system must be isolated before work begins,
and
cannot be restarted until work has
finished
Isolating the system makes it safer to work
on. If the system is isolated there is a
much lower chance that:
- A
person is electrocuted.
- Oil
or fuel spills into the sea.
- A
fire starts.
- Equipment
could be damaged.
It is the skipper’s responsibility to make sure
that systems are isolated. Legally, this
responsibility cannot be delegated to
contractors. It is always skipper who is responsible for the safety of all
workers on board the vessel.
If there is an environmental incident (eg: a fuel
spill), particularly one that could have been avoided by isolation, the owner
and skippers as well as the contractor can all be found responsible.
! Action points
Turn
the supply off to the equipment that is going to be maintained. You can:
1. Put a piece of tape
across it and write “Do Not Turn On” and your name on it.
2. Use a designed tag-out
card.
- Before removing any tag to start equipment, check with the person
whose name is on the tag or tape that work has been completed and that it
is safe to operate.
- Always check yourself that the system looks safe to operate after
it has been worked on.
- If a contractor will come on board to do maintenance work when the
crew are not there, isolate the system before you leave.
