Filtering facepiece respirator definition

Filtering facepiece respirator means a negative pressure air purifying particulate respirator with a filter as an integral part of the facepiece or with the entire facepiece composed of the filtering medium. Filtering facepiece respirators are certified for use by the National Institute for Occupational Safety and Health (NIOSH).

Filtering facepiece respirator means a tight-fitting, negative pressure, particulate respirator, where the particulate filter is the facepiece itself. Such respirators are often referred to as “dust masks,” but dust masks that are not certified by the National Institute for Occupational Safety and Health are not respirators. The most common filtering facepiece respirators for general use are known as N-95 respirators.

  • They may come with or without a face shield.● Filtering facepiece respirator (FFR): A protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles.

  • Employers must ensure that employees wearing filtering facepiece respirators are trained in the proper use of the respirators, including putting them on and removing them, any limitations on their use, how to care for the respirator, and the ability to demonstrate a seal check as described in section (B) of this appendix.(B) Filtering facepiece respirator user seal check.


More Definitions of Filtering facepiece respirator

Filtering facepiece respirator means a tight-fit- ting, half-facepiece, negative-pressure, particulate air-purify- ing respirator with the facepiece mainly composed of filter material. These respirators do not use cartridges or canistersand may have sealing surfaces composed of rubber, silicone or other plastic-like materials. They are sometimes referred to as "dust masks."
