This author examined why firefighters at Clallam County Fire District No 3 (CCFD3) are resistant to using Compressed Air Foam Systems (CAFS) fire streams. CCFD3 had experienced that despite placing four engines with CAFS capability in service, providing CAFS fire stream training, and occasional use of CAFS fire streams, most firefighters are still resistant to its use. The purpose of this research is to identify the concerns that are making firefighters resistant to using CAFS fire streams, and to recommend solutions that give firefighters the confidence in CAFS fire streams for use during fire suppression activities. The descriptive research methodology was utilized. Procedures utilized were literature review, knowledge and skills evaluations, interviews and surveys.The procedures were intended to produce answers to the following research questions: 1) Are firefighters not using CAFS fire streams because of a resistance to the change process when CAFS was implemented? 2) Are firefighters not using CAFS fire streams because of a deficiency in training and education? 3) Are firefighters not using CAFS fire streams because of a deficiency in apparatus or equipment? and 4) Are firefighters not using CAFS fire streams because flow rate capability is less than that of water only fire streams? The results of the research indicated poor implementation and lack of comprehensive training led to competency problems. Uncorrected, these problems developed into a perception of CAFS being problematic and unreliable.Recommendations included discussing results of the research with the shift officers, development of a standardized training plan that addresses fire behavior and foam theory in addition to skill requirements, modification of CCFD3 procedure to allow CAFS fire stream during interior fire attack when appropriate, and a CAFS program review in two years.
