Abstract
The Bureau of Mines proposed a new series of human subject certification tests for self-contained breathing apparatus (scba) in 1977. Eight scba's, one open-circuit and seven closed-circuit, were worn by test subjects while performing the tests. The major conclusions were: (1) the proposed tests are not too physically demanding. (2) There should be a minimum test subject weight. (3) The important apparatus variables to be measured are breathing resistance, temperature, and co2 and 02 concentrations of the inhaled gas. (4) Continuous monitoring should be employed. (5) New pass-fail criteria based on realistic estimates of the physiological requirements of the user are needed. (6) Breathing machines should be used for the majority of certification testing. (7) A more realistic ergonomics test than that presently proposed is needed. (8) System gas leak and facepiece leakage tests are also needed.
