Qualitative Fit Testing of Medium - Size N95/FFP2 Respirators on Iranian Health Care Workers

Do Respirators Protect Health-Care Workers From Airborne Infectious Diseases?

The burdensome nature of wearing a respirator has driven controversy on the effectiveness of respiratory protection for health-care workers for many years. The safety and industrial hygiene communities have insisted on appropriate, dutiful, compulsive practice that includes fit testing. Legislative amendments have blocked elements such as fit testing. Most importantly, health-care workers have ...

A cluster randomized clinical trial comparing fit‐tested and non‐fit‐tested N95 respirators to medical masks to prevent respiratory virus infection in health care workers

BACKGROUND We compared the efficacy of medical masks, N95 respirators (fit tested and non fit tested), in health care workers (HCWs). METHODS A cluster randomized clinical trial (RCT) of 1441 HCWs in 15 Beijing hospitals was performed during the 2008/2009 winter. Participants wore masks or respirators during the entire work shift for 4 weeks. Outcomes included clinical respiratory illness (CR...

Assessing real-time performances of N95 respirators for health care workers by simulated workplace protection factors

To assess performances of N95 respirators for Health Care Workers (HCWs) in a simulated health-care setting, we measured the Simulated Workplace Protection Factors (SWPFs) in real-time from the volunteers. A total of 49 study subjects, wearing 3 M respirator Model N95 1860 and 1860S, were fit tested using the OSHA Exercise Regimen. The test subjects were asked to perform simulated scenarios, in...
