Abstract
Respiratory testing equipment was developed and evaluation techniques for respiratory protective equipment were modified as a result of a series of studies performed for NIOSH in 1977. Major efforts of the research program included completion of a study comparing respiratory quantitative fit test results as obtained with a liquid aerosol, a solid aerosol, and a gas test agent; completion of a study to determine the feasibility of constructing equivalent high efficiency particulate filters to replace sorbent canisters for quantitative fit tests using aerosol test agents; development of quantitative fit test procedures for powered air purifying respirators; development of particulate filter service life test methods using sodium chloride (7647145) aerosol; and completion of an interlaboratory comparison of sodium chloride aerosol penetration through mechanical dust, fume, and mist respirator filters. The results and implications of these studies are discussed.
