What are Respirators?

Respirators are a form of personal protective equipment that provide respiratory protection against airborne contaminants. Respirators can either filter the ambient air or provide clean breathing air in the case of Self-Contained Breathing Apparatus (SCBA) systems.

What is Respirator Fit Testing?

A respirator fit test consists of several exercises designed to stress the respirator/face seal during which the test subject wears the respirator to be tested, and the ratio of the challenge agent concentration inside the mask to the ambient concentration is measured. This Ratio is the Fit Factor. In the CNC method, ambient ultra-fine particulates are the challenge agent.

Respirator Fit Testing Requirements

OSHA requires that respirator fit testing be done on tight-fitting respirators. If the respirator does not rely on a tight seal around the face (i.e., PAPRs), it does not require testing. Tight-fitting respirators including Filtering Facepieces such as N95 masks require either qualitative or quantitative fit testing. Full Face respirators must be tested with a quantitative method because the minimum Fit Factor required for a Full Face respirator is 500, which is not achievable with qualitative methods.

Fit Testing Frequency

Respirator fit testing must be done prior to using a mask on the job. The fit test is valid for one year unless there are any major changes to the face of the user. This may include major dental work, facial scarring, a visible change in weight or facial surgery. The fit test is only valid for the particular make, model, and size of the respirator tested.
