A review was made of literature dealing directly with human subject testing of self contained breathing apparatus (SCBA). The review discussed the history and background of human use testing of SCBA; the metabolic rates and working environments of the SCBA user such as miners and firefighters; major changes in the man test procedure; a summary of energy expenditures for SCBA user related occupational tasks; factors influencing metabolic requirements while wearing SCBA including weight of the equipment, SCBA type, heat stress, oxygen and carbon-dioxide concentrations; continuous monitoring situations; related performance criteria including breathing resistance, breathing gas temperature, carbon-dioxide concentrations, and oxygen concentration; wearer comfort and psychological factors. The authors conclude that the present methods used to test SCBA are outdated and need revision. They urge that many of the above factors be considering in developing or proposing any SCBA certification or performance requirements.
