| Abstract |
The primary respiratory hazards to fire fighters are high carbon monoxide concentrations and oxygen deficiency. A self-contained personal sampler was developed to monitor fire fighters' exposures to both hazards in actual fires. A hot-wire combustible gas detector was modified to be specific for CO measurements in the range of 0.02 to 10%, and a membrane sensor was used to measure oxygen in the range of 0 to 21%. The data are recorded on a small cassette tape recorder; the output signals of the CO and oxygen circuits are fed alternatively, by means of a timing microswitch assembly, to a voltage-to-frequency converting circuit, and the frequency signals recorded on tape. Tests conducted on various fire gases indicate mean errors of 14.0% and 3.2% in the carbon monoxide and oxygen measurements, respectively. The various advantages presented by this sampler are listed. |
