Cooling Effectiveness of Three Fire Fighting Agents

摘要

Four fire fighting tests were conducted with an instrumented warhead section of a steel cased inert MK 101 depth bomb engulfed in an aircraft fuel fire. The tests were performed to determine the relative cooling effectiveness of three fire fighting agents; water fog, straight stream water, and low expansion foam (two tests using different nozzle configurations were performed with foam). Of the three agents, straight stream water was the most effective in cooling the inside of the weapon; however, neither method of water application could extinguish the fire. Foam, though capable of extinguishing the fire, was ineffective in cooling the inside of the weapon. (Author)
