Continuing concern about exposure to respiratory hazards at various workplaces and prevalent pandemics such as H1N1/09 influenza and COVID-19, have necessitated a need for more research regarding respirators. Quantitative fit testing (QNFT) is a critical component of an OSHA compliant respiratory protection program. QNFTs are often performed in environments where temperature and relative humidity (RH) vary. However, no study has investigated the possible effects of these parameters on penetration and QNFT results.
This comparative study utilized condensation nuclei counter (CNC) and controlled negative pressure (CNP) methods to quantitatively determine simulated mannequin fit factors (SMFFs) and human fit factor (HFFs) using …
