Turn ship off-wind. Spillage on deck Wash spillage 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 water spray, foam or dry chemical. Do NOT use water jet. 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. Spray nozzles.
