Emergency procedures

Action

Avoid all sources of ignition (e.g. naked lights, unprotected light bulbs, electric handtools).

Spillage on deck

Stop leak if practicable. Let spilt liquid evaporate, but keep clear.

Spillage under deck

Provide adequate ventilation. Stop leak if practicable. Let spilt liquid evaporate, but keep clear.

Fire on deck

Use water spray, foam or dry chemical from as far away as practicable.
Keep adjacent receptacles cool with copious quantities of water. Remove undamaged cooled receptacles to a safe place.

Fire under deck

Batten down; use ship's fixed fire-fighting installation. Otherwise adopt action as for "On deck".

Special equipment to be carried

Protective clothing (gloves, boots, coveralls, headgear).
Self-contained breathing apparatus.
Spray nozzles.
