The N95 is the most well-liked collection 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 courses, 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 exposed to grease aerosols:
N95, N99, & N100. These filters are not to be used with oil aerosols. These must be used in environments exposed to particulates which do not comprise oil. In lots of cases, the n- respirators can be reused multiple times.
R95, R99, & R100. These filters are oil resistant. The r- respirators can be utilized in atmospheres containing particulates any solid or liquid hazard including oil-primarily based hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be utilized in any setting exposed to hazardous particulates. The p- respirators are topic to time of use limitations.
The filter effectivity number refers to the share of airborne particulates that had been removed in testing: 95%, 99%, and 100%. If a masks is NIOSH approved then it’ll have a stamp of approval class printed on the respirator.
NIOSH approved masks also come in several sizes, and a well fitting masks is vitally important. When test-fitting an N95 mask or different particulate respirator masks, comply with these simple steps:
1. Press the mask (respirator ) firmly towards 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 bottom headband over the head and place beneath your ears.
3. With each arms, mold the metal nosepiece to the form of your nose.
4. To test match, cup both arms over the respirator and exhale vigorously. If air flows round your nostril, tighten the nosepiece: if air flows across the edges of the respirator, reposition the headbands to suit better and test once more until there is no such thing as a air leakage.
Earlier than choosing the right masks, additionally it is suggested that you just converse with skilled industrial safety personnel about an assessment of your specific environment.
