• Description:
  The objective of this study is as follows: To evaluate the fitting characteristics of an elastomeric half-mask respirator worn by a 25- subject panel being fit-tested while exposed to a NaCl-based surrogate of the combustion aerosol. The conclusions of this study were as follows: The respirator produced a geometric mean fit factor of 4,779 (GSD = 9.1); Among the challenge conditions, wet-shaved face was associated with higher fit factor (GM = 267) than dryshaved face (GM = 74); No significant difference was found between other challenge conditions; Future studies are needed to include more subjects with various face dimensions along with different shaving and wetting/sweating conditions.
