Emergency procedures

Action

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

Spillage on deck

Wash overboard with copious quantities of water from as far away as practicable.

Spillage under deck

Collect spillage, where practicable, using absorbent material for liquids, for safe disposal.

Fire on deck

Use water spray from as many hoses as possible from as far away as practicable.

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.
