N95 Respirator Mask Types: Basic Data  

N95 Respirator Mask Types: Basic Data

The N95 is the preferred series 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 oil aerosols:

N95, N99, & N100. These filters are usually not to be used with oil aerosols. These ought to be utilized in environments exposed to particulates which do not include 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-primarily based hazards. These are one-time use masks.

P95, P99, & P100. These filters are oil proof. These respirators can be used in any atmosphere uncovered to hazardous particulates. The p- respirators are subject to time of use limitations.

The filter effectivity number refers to the proportion of airborne particulates that have been removed in testing: 95%, ninety nine%, and a hundred%. 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 numerous sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or other particulate respirator mask, observe 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 beneath your ears.

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

4. To test fit, cup each 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 higher and test once more until there is no air leakage.

Before choosing the right mask, it is also prompt that you speak with experienced industrial safety personnel about an evaluation of your particular environment.
