The N95 is the most popular sequence of particulate respirator masks that meet United States government standards. The face masks are tested to reduce publicity to airborne contaminates by NIOSH – the National Institiute for Occupational Safety and Health. NIOSH has nine total approval classes, N95, N99, N100, R95, R99, R100, P95, P99, P100 organized by oil compatibility and filter efficiency.
The letter signifies how the filter tests in environments uncovered to grease aerosols:
N95, N99, & N100. These filters usually are not for use with oil aerosols. These ought to be used in environments exposed to particulates which don’t include oil. In many cases, the n- respirators will be reused a number of times.
R95, R99, & R100. These filters are oil resistant. The r- respirators can be used in atmospheres containing particulates any strong or liquid hazard including oil-based mostly hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be utilized in any setting uncovered to hazardous particulates. The p- respirators are subject to time of use limitations.
The filter efficiency number refers back to the share of airborne particulates that were removed in testing: ninety five%, ninety nine%, and a hundred%. If a mask is NIOSH approved then it will have a stamp of approval class printed on the respirator.
NIOSH approved masks additionally come in numerous sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or different particulate respirator masks, comply with these easy steps:
1. Press the masks (respirator ) firmly against the face with the outside nosepiece on the bridge of your nose.
2. Stretch and position the top headband on the back of your head above your ears. Stretch the underside headband over the head and place beneath your ears.
3. With both hands, mold the metal nosepiece to the form of your nose.
4. To test match, cup each fingers over the respirator and exhale vigorously. If air flows around your nose, tighten the nosepiece: if air flows across the edges of the respirator, reposition the headbands to fit higher and test again till there is no air leakage.
Earlier than selecting the best mask, it is also suggested that you just speak with experienced industrial safety personnel about an assessment of your specific environment.
