Abstract Details

2008, MS, University of Cincinnati, Medicine : Industrial Hygiene (Environmental Health).
This study was conducted to determine the percentage of time the OSHA Rule of Thumb for respirator cartridge service life agrees with a computer calculated model for CBRN-approved air purifying respirators. Test conditions used and organic vapors evaluated in the OSHA/NIOSH MultiVapor software model were chosen from the NIOSH certification testing criteria for CBRN respirators. Service life predicted from the software model evaluated at concentrations of 2600, 260, 26, and 2.6 ppm was compared to the OSHA Rule of Thumb. When determining service life for CBRN approved respirators, applying the OSHA Rule of Thumb was found to be most successful at 26 ppm (96.6%). Success rate of the OSHA Rule of Thumb was found to be 93.2% and 94.9% at the concentrations of 260 and 2.6 ppm, respectively. Statistical analysis of the data indicates the OSHA Rule of Thumb to be acceptable in determining service life for CBRN approved respirators.
