Emergency procedures

Action

Avoid all sources of ignition (e.g. naked lights, unprotected light bulbs, electric handtools).
Turn ship off-wind.

Spillage on deck

Use of water on substance may cause violent reaction. Collect spillage, where practicable, using absorbent material and dispose of overboard in a safe manner. Wash remainder overboard with copious quantities of water.

Spillage under deck

Provide adequate ventilation. Collect spillage, where practicable, using absorbent material, for safe disposal.

Fire on deck

Use dry chemical. If possible remove receptacles likely to be involved.

Fire under deck

Batten down; use ship's fixed fire-fighting installation (not water). Otherwise adopt action as for "On deck".

Special equipment to be carried

Protective clothing (gloves, boots, coveralls, headgear).
Self-contained breathing apparatus.
Dry chemical.
