Results of performance testing of the 3M Model BE10 powered air-purifying respirator PAPR are described. Three series of tests were performed 1 breakthrough time determinations of PAPR Cartridge Model AP3 against Sarin GB 2 GB vapor penetration determination of entire PAPR systems using manikin headform and simulated breathing, and 3 corn-oil protection factor determinations of PAPR systems using human subjects. Results indicate that cartridges provide adequate resistance to GB penetration against high-concentration challenges, but that corn oil aerosol and high concentration GB vapor penetration into the breathing zone of the PAPR occurs at high levels, possibly through the hood-type head enclosure andor the exhalation valve.
