Research progress on air supply duration of air breathing apparatus for firefighters
In order to fully understand the acting mechanism and influence degree of multiple factors on the duration of self-contained breathing apparatus (SCBA),effectively protect the firefighters' respiratory system from the hurt of toxic and haz-ardous gases,enhance the rescue ability of firefighters,the technologies and strategies for prolonging the duration of SCBA were studied. Based on the research status at home and abroad,the literature review method was used to classify according to the personal factors,equipment factors,and environmental factors. The influence of different ways on the duration of SCBA was analyzed,and it was proposed to further improve the sustainable duration and intelligence degree of SCBA,which will become the focus of future research. The results show that changing the structural design parameters of SCBA reasonably is an effec-tive method to prolong its duration. The research results can provide some reference for the research and development of intel-ligent SCBA.
