Evaluation of half-face respirator fit in an Iranian petrochemical company's workers

Introduction: The performance of respirator-face piece is depending on a good contact between the worker's face and the respirator. Improper sealing can cause reduction in performance of respirators to protect health and safety of workers against risks related to chemical agents at work. This study is aimed to evaluate the fitness of half-face respirators and other related factors on it in an...

The effect of gender and respirator brand on the association of respirator fit with facial dimensions.

This study examined the association of facial dimensions with respirator fit considering the effect of gender and respirator brand. Forty-one subjects (20 white females and 21 white males) participated in the study. Each subject was measured for 12 facial dimensions using anthropometric sliding and spreading calipers and a steel measuring tape. Three quantitative fit tests were conducted with t...

Respirator Donning in Post-Hurricane New Orleans

We evaluated correctness of N95 filtering facepiece respirator donning by the public in post-hurricane New Orleans, where respirators were recommended for mold remediation. We randomly selected, interviewed, and observed 538 participants, using multiple logistic regression for analysis. Only 129 (24%) participants demonstrated proper donning. Errors included nose clip not tightened (71%) and st...
