Emergency procedures

Spillage on deck

Collect spillage for safe disposal. Wash remainder overboard with copious quantities of water. Do not use sawdust or other combustible materials as absorbents.
Contaminated clothing must be removed and washed carefully with copious quantities of water.

Spillage under deck

Collect spillage for safe disposal. Do not use sawdust or other combustible materials as absorbents.
Contaminated clothing must be removed and washed carefully with copious quantities of water.

Fire on deck

Use copious quantities of water to fight a fire. Remove receptacles likely to be involved or keep them cool with copious quantites of water.

Fire under deck

Ship's fixed fire-fighting installation may not be effective. Adopt action as for "On deck".

Special equipment to be carried

Protective gloves, boots and goggles.
Self-contained breathing apparatus.
