• Description:
  Results were provided of a comparison made between exposures observed in end use applications and those normally observed in manufacturing situations. Several hundred paired personal and area samples were collected. A significant number of fibers was noted to adhere to the sidewalls of the cassettes and to the sampling cowls. These fibers were also counted in the study. The mean total fiber (both glass fiber and all other fiber) exposures of individuals installing batt, blanket, and roll insulation was 0.17 fiber/cubic centimeter (f/cm3) for filters only and 0.24f/cm3 for filters and cowls combined. Additional analyses revealed that 50% were glass fibers. Of the glass fibers, 75% were of a respirable size. Loose fill loaders and installers were exposed to higher mean concentrations of total fiber in the range of 0.23 to 0.91f/cm3 for filters only and 0.37 to 1.3f/cm3 for filters and cowls combined, primarily due to the nature of the installation process. Additional analyses revealed that 50 to 75% were glass fibers, of which 50 to 75% were of a respirable size. The total fiber exposures of both the insulation production employees and end users were appreciably below the NIOSH recommended limits for glass fibers of 3f/cm3.
