Emergency procedures Action Avoid all skin contact. Avoid all sources of ignition (e.g. naked lights, unprotected light bulbs, electric handtools). Spillage on deck Stop leak if practicable. Let spilt liquid evaporate. Spillage under deck Provide adequate ventilation. Stop leak if practicable. Let spilt liquid evaporate. Fire on deck Use water spray, foam or dry chemical from as far away as practicable. Keep adjacent receptacles cool with copious quantities of water. 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".
