Emergency procedures Action Due to low temperature, SPILLAGE may damage ship's construction. Avoid all contact, even when wearing protective clothing. Do not direct water jet straight onto the spill. Spillage on deck Stop leak if practicable. Use water jets from as far away as practicable to accelerate evaporation, not directing them strsight onto the spill. Ensure that direction of jet does not drive liquid towards the emergency team or into confined areas. Do not direct water jet at vent discharge piping. Spillage under deck Provide adequate ventilation. Adopt action as for "on deck". Fire on deck Use copious quantities of water from as far away as practicable to cool surroundings and adjacent receptacles. When possible, remove undamaged cooled receptacles to a safe place. Fire under deck Batten down; use ship's fixed fire-fighting installation. Otherwise adopt action as for "On deck". Special equipment to be carried Suitable protective gloves. Self-contained breathing apparatus. Spray nozzles. Decision trees Decision trees No decision trees available No additional data
