Abstract

Purpose. The paper is devoted to the justification of the tactical and technical characteristics and application methods of compressed air foam systems to extinguish fires.

Methods. Analysis of the results of experimental studies of compressed air foam systems and the results of calculations of the engineering method of hydraulic calculation of rubber hose lines of compressed air foam.

Findings. Extinguishing of conditional hearth Class A fire by compression foam required 2 times less time and extinguishing substances than with using the barrel SVP-2. There is the possibility of supplying compression foam to 18, 25 and 32 floors of high-rise buildings. The pressure drop along the length of hose line when applying dry compression foam were lower than when applying wet compression foam. Use of compressed air foam at low temperatures in hose line does not create ice plugs and does not cause damage to fire hose.

Application field of research. The research results can be used in fire rescue departments for firefighting by compressed air foam system.

Conclusions. The analysis defines the distinctive features which differ compressed air foam systems from traditional foam fire extinguishing technologies in tactical and technical characteristics. The field of application of foam generating systems with compressed air is defined.
