N95 Respirator Mask Types: Fundamental Information

The N95 is the most well-liked sequence of particulate respirator masks that meet United States government 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 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 exposed to oil aerosols:

N95, N99, & N100. These filters are usually not for use with oil aerosols. These should be utilized in environments uncovered to particulates which don't contain 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 solid 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 used 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 percentage of airborne particulates that had been removed in testing: 95%, 99%, and a hundred%. If a masks is NIOSH approved then it is going to have a stamp of approval class printed on the respirator.

NIOSH approved masks also come in different sizes, and a well fitting mask is vitally important. When test-fitting an N95 masks or different particulate respirator masks, follow these easy 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 below your ears.

3. With each fingers, mold the metal nosepiece to the form of your nose.

4. To test fit, cup both fingers over the respirator and exhale vigorously. If air flows around your nose, tighten the nosepiece: if air flows around the edges of the respirator, reposition the headbands to fit better and test once more until there isn't a air leakage.

Earlier than choosing the right masks, it's also prompt that you just communicate with experienced industrial safety personnel about an evaluation of your specific environment.
