Engineering Analysis of Threshold Compressed Air Foam Systems (CAFS)

摘要

An engineering analysis of compressed air foam systems (CAFS) deals only with methods of producing expanded water (foam) and delivering it to the end of a hose, and not with the effect of the expanded water on a wildfire nor with foaming agents themselves. CAFS are a brute force method of producing foam; therefore, almost any foaming agent can be used. CAFS units are cost-effective since, under some circumstances, they can provide a significant extension of the water carried by a fire engine. If CAFS units were to be used by the Forest Service, there would be added costs for the engine, additional fire crew training, and new procurement documentation. However, the use of CAFS may extend and enhance the water carried by an engine.
