Emergency procedures

Action

Turn ship off-wind.

Spillage on deck

Use of water on substance may cause violent reaction. Wash overboard with copious quantities of water from as far away as practicable.

Spillage under deck

Not applicable.

Fire on deck

If possible remove receptacles likely to be involved or keep them cool with water.

Fire under deck

Not applicable.

Special equipment to be carried

Protective clothing (gloves, boots, coveralls, headgear).
