Previous SEL Number: 01AR-06-DISP

Description: A filtering facepiece respirator certified by NIOSH

National Institute for Occupational Safety and Health

under 42 CFR

Code of Federal Regulations

84 and classified as a disposable particulate respirator with a filter efficiency of N100, R100, or P100.

ImportantFeatures: Manufactured in a variety of shapes and sizes. The filtering facepiece respirator shall have a four-point suspension system and elastomeric seal. As an option, the filtering facepiece respirator may have an exhalation valve.
The filters are certified to three categories of oil resistance, as indicated by the letter prefix (N=Not Resistant to Oil, R=Somewhat Resistant to Oil (limited to one work shift), P=Strongly Resistant to Oil).

Filtering facepiece respirators certified to N, R, or P100 have a filter efficiency of at least 99.97% of airborne particles.

Operating Considerations: These respirators are considered "tight-fitting" and therefore fit testing is required under 29 CFR

Code of Federal Regulations

1910.134.

Particulate respirators are known as air-purifying respirators because they protect by filtering particles out of the air as you breathe. These respirators protect only against particles, not gases or vapors. Therefore, they are not effective for use in chemical, firefighting or fire escape applications. These respirators are not suitable for use in IDLH or oxygen-deficient environments. However, since respirable dusts and airborne biological agents such as bacteria or viruses are particles, they can be filtered by particulate respirators.

Respirator type should be chosen based upon the anticipated hazard and wearer activity. For example, "N" respirators would be well suited for the medical/airborne pathogen environment, while "P" respirators would be more applicable for industrial settings where aerosolized oils are present.

NIOSH-approved filtering facepiece respirators exist with other efficiencies (such as N-95); however, the highest efficiency tested under 42 CFR

Code of Federal Regulations

part 84 is recommended in order to reduce the potential contaminant concentration inside the facepiece to the lowest possible level.
