N95 Respirator Mask Types: Primary Info
The N95 is the most popular series of particulate respirator masks that meet United States authorities 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 oil aerosols:
N95, N99, & N100. These filters aren’t to be used with oil aerosols. These must be used in environments uncovered to particulates which do not contain oil. In lots of cases, the n- respirators might 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 solid or liquid hazard together with 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 atmosphere exposed to hazardous particulates. The p- respirators are subject to time of use limitations.
The filter effectivity number refers to the percentage of airborne particulates that had been removed in testing: ninety five%, 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 additionally come in several sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or different particulate respirator masks, comply with these straightforward 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 highest headband on the back of your head above your ears. Stretch the bottom headband over the head and place under your ears.
3. With both hands, mold the metal nosepiece to the shape of your nose.
4. To test fit, cup each hands over the respirator and exhale vigorously. If air flows around your nostril, tighten the nosepiece: if air flows across the edges of the respirator, reposition the headbands to fit higher and test again till there isn’t any air leakage.
Earlier than choosing the proper masks, it’s also instructed that you simply speak with skilled industrial safety personnel about an assessment of your specific environment.
