Results of performance testing of commercial powered air purifying respirator PAPR systems and cartridges are described. Three series of tests were performed breakthrough time determinations of cartridges against Sarin GB, GB vapor penetration determination of entire PAPR systems using manikin headform and simulated breathing, and cornoil protection factor determinations of PAPR systems using human subjects. Results indicate that cartridges provide complete penetration resistance against 200 mgm3 GB challenge concentrations for 60 minutes, but that unacceptably high levels of GB vapor and corn oil aerosol may penetrate into the breathing zone of the PAPRs.
