||Correlation between quantitative fit factors and workplace protection factors measured in actual workplace environments at a steel foundry
||Nov.-Dec. 2003, Vol.64, No.6, p.730-738. Illus. 25 ref.
||This study investigated the protective effect of good and poor-fitting half-facepiece, air-purifying respirators at a steel foundry and examined the correlation between workplace protection factors (WPFs) and quantitative fit factors (FFs). Fifteen volunteers participated in the study. Each subject was fit-tested with two respirator models in three sizes. Each worker wore the respirator twice per day (at the beginning of the shift and following the lunch break) for two days. WPFs were measured by collecting ambient and in-facepiece air samples simultaneously. WPF values were significantly correlated with the FFs. Respirator fit-factor was shown to be a meaningful indicator of respirator performance in actual workplace environments.
