Emergency procedures Action Avoid all sources of ignition (e.g. naked lights, unprotected light bulbs, electric handtools). Turn ship off-wind. Spillage on deck Stop leak if practicable. Let spilt liquid evaporate, but keep clear. Spillage under deck Not applicable. 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 Not applicable.
