Emergency procedures

Action

Turn ship off-wind.

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.

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.
