N95 Respirator Mask Types: Primary Info

The N95 is the preferred series 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 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 must be used in environments exposed to particulates which do not contain oil. In many cases, the n- respirators might be reused a number of times.

R95, R99, & R100. These filters are oil resistant. The r- respirators can be utilized 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 surroundings uncovered to hazardous particulates. The p- respirators are topic to time of use limitations.

The filter efficiency number refers to the share of airborne particulates that had been removed in testing: 95%, ninety nine%, and 100%. If a mask is NIOSH approved then it will have a stamp of approval class printed on the respirator.

NIOSH approved masks also come in several sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or other particulate respirator mask, follow these simple steps:

1. Press the mask (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 bottom headband over the head and position below your ears.

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

4. To test fit, cup both hands over the respirator and exhale vigorously. If air flows round your nostril, tighten the nosepiece: if air flows around the edges of the respirator, reposition the headbands to fit higher and test again till there is no such thing as a air leakage.

Before choosing the right mask, it can also be advised that you simply speak with skilled industrial safety personnel about an evaluation of your particular environment.
