Emergency procedures
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
Collect spillage, where practicable, using inert absorbent material for liquids, for safe disposal.
Fire on deck
If possible remove receptacles likely to be involved or keep them cool with water.
Fire under deck
Adopt action as for "On deck".
Special equipment to be carried
Protective clothing (gloves, boots, coveralls, headgear).
