Abstract : A self-contained foam-water sprinkling system was developed for combatting fires on and around diesel engine driven generators on submarines. The system recommended can effectively control fires on the engine and in the bilge area. Additional manual use of portable extinguishers is recommended for control of fuel and lube oil spray fires. In the fire tests conducted, the AFFF sprinkling system produced control times (90% bilge fire out) of 5 to 7 seconds and total extinguishment times of 15 to 39 seconds using a 30 gallon foam-water storage tank and a piping system with six directional spray nozzles. Stored nitrogen was used to propel the agent. Automatic fire detection and extinguishing system actuation is recommended due to extremely rapid development of intolerable heat and smoke conditions expected in such a fire situation. (Author)
