The N95 is the preferred sequence of particulate respirator masks that meet United States authorities standards. The face masks are tested to reduce exposure 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 oil aerosols:
N95, N99, & N100. These filters should not to be used with oil aerosols. These should be used in environments exposed to particulates which do not contain oil. In many cases, the n- respirators can be reused multiple times.
R95, R99, & R100. These filters are oil resistant. The r- respirators can be used 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 atmosphere exposed to hazardous particulates. The p- respirators are topic to time of use limitations.
The filter efficiency number refers back to the share of airborne particulates that have been removed in testing: ninety five%, 99%, and a hundred%. If a masks is NIOSH approved then it should have a stamp of approval class printed on the respirator.
NIOSH approved masks also come in different sizes, and a well fitting masks is vitally important. When test-fitting an N95 masks or different particulate respirator masks, observe these easy steps:
1. Press the mask (respirator ) firmly in opposition to 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 form of your nose.
4. To test fit, cup both arms over the respirator and exhale vigorously. If air flows around your nostril, tighten the nosepiece: if air flows around the edges of the respirator, reposition the headbands to fit better and test again till there is no air leakage.
Earlier than choosing the proper masks, it’s also steered that you simply communicate with experienced industrial safety personnel about an assessment of your particular environment.
