• Description:
  The desired protective factor for self-contained breathing apparatus used in the fire service is proposed at 100 based on a series of tests with a personal air sampler which revealed maximum air concentrations of carbon-monoxide (630080) of approximately 20,000 ppm during fire fighting episodes. A series of 74 incidents were studied using a combustible gas detector modified to be specific for carbon-monoxide. The data are recorded on a cassette recorder using a voltage to frequency converter. A study of the respiratory minute volume during active work while wearing open-circuit, self-contained breathing apparatus indicated a median value of 60 liters per minute and 70 liters for the 80 percentile group. If the device is to have a service life of 30 minutes, the stored air capacity must be 1800 liters, and 2100 liters for the median and 80 percentile values respectively.
