N95 Respirator Masks Types: Fundamental Data
The letter signifies how the filter tests in environments exposed to grease aerosols:
N95, N99, & N100. These filters aren't to be used with oil aerosols. These ought to be used in environments uncovered to particulates which do not include oil. In many cases, the n- respirators could 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 atmosphere uncovered to hazardous particulates. The p- respirators are subject to time of use limitations.
The filter efficiency number refers back to the share of airborne particulates that had 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 masks or different particulate respirator mask, comply with 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 highest headband on the back of your head above your ears. Stretch the underside headband over the head and position below your ears.
3. With both fingers, mold the metal nosepiece to the form of your nose.
4. To test fit, cup each arms over the respirator and exhale vigorously. If air flows round 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 any air leakage.
Before choosing the proper mask, it is also recommended that you just speak with skilled industrial safety personnel about an assessment of your specific environment.
