1993 Fleet Doctrine Evaluation Workshop: Phase 1. Class A Fire/Vertical Attack

Abstract : A series of firefighting tests were conducted to develop and refine firefighting doctrine for vertical attack of a Class A fire in a below-decks, limited access space. Key findings in this test series included using an access team to gain entry to the space and monitoring pressure build-up when indirect firefighting is used. Cool vests provided a significant improvement in the reduction of heat stress. Too much communication, particularly between the Team Leader and On-Scene Leader, can hinder the effectiveness of firefighting. Cooling of spaces used to gain access to a fire can create steam that makes the space temporarily untenable. Active desmoking during the firefighting attack can improve the overall damage control effort. Based on these and previous Fleet Doctrine Evaluation Tests, it is proposed that NSTM 555 and NWP 62-1 be revised to include doctrine and tactics for vertical attack and active desmoking of a Class A fire.
