Emergency procedures
Action
Turn ship off-wind.
Spillage on deck
Collect spillage, where practicable, using absorbent material for safe disposal. 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 copious quantities of water or other media to fight fire. If possible remove receptacles likely to be involved or keep them cool with copious quantities of water.
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.
