In vivo protective performance of N95 respirator and surgical facemask

American Journal of Industrial Medicine, 2006
AbstractBackgroundThe SARS outbreak in 2003 has spawned a major controversy concerning protective performance facemasks for healthcare workers. This study reports a study on in‐vivo protective performance of surgical masks and N95 respirators.MethodsTypical surgical masks and N95 respirators used in Hong Kong hospitals were tested in comparison with ...

Workplace Protection Factors for an N95 Filtering Facepiece Respirator

Journal of Occupational and Environmental Hygiene, 2007
This study evaluated the workplace performance of an N95 filtering facepiece, air-purifying respirator in a steel foundry. Air samples were collected inside and outside respirators worn by workers who were properly trained and qualitatively fit tested. For most workers, three or four pairs of air samples were collected on each of 2 days.

Fitting Characteristics of Eighteen N95 Filtering-Facepiece Respirators

Journal of Occupational and Environmental Hygiene, 2004
Four performance measures were used to evaluate the fitting characteristics of 18 models of N95 filtering-facepiece respirators: (1) the 5th percentile simulated workplace protection factor (SWPF) value, (2) the shift average SWPF value, (3) the h-value, and (4) the assignment error.

Performance of N95 Respirators: Reaerosolization of Bacteria and Solid Particles

AIHAJ, 1997
If a respirator does not contain an exhalation value, and the respirator wearer sneezes or coughs, one may expect previously collected particles to be reaerosolized. This may be of special concern in environments contaminated with airborne microorganisms.
