Emergency procedures Action Due to low temperature, SPILLAGE may damage ship's construction. Avoid all sources of ignition (e.g. naked lights, unprotected light bulbs, electric handtools). 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 straight onto the spill. Ensure that direction of jet does not drive liquid towards the emergency team, into confined areas or near ignition sources. 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 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 clothing (gloves, boots, coveralls, headgear). Self-contained breathing apparatus. Remarks by UN no. HYDROGEN, REFRIGERATED LIQUID (UN No. 1966) Flames may be invisible. Decision trees Decision trees No decision trees available No additional data
