Respirator fit testing is a mandatory annual procedure that ensures a specific respirator model provides a reliable, airtight seal for an individual worker's face.
Respirators only protect workers when the equipment is appropriate for the hazard and forms a reliable seal. A fit test confirms that a specific make, model, style, and size of tight-fitting respirator fits the individual worker.
Who needs a respirator fit test?
Employees must be fit tested when their work requires a tight-fitting respirator, including many filtering facepiece respirators, elastomeric half- or full-face respirators, tight-fitting powered air-purifying respirators, and self-contained breathing apparatus. Loose-fitting hoods do not rely on a face seal and generally do not require fit testing.
How often is fit testing required?
OSHA requires fit testing before a worker first uses a tight-fitting respirator and at least annually afterward. A new test is also needed whenever the worker changes to a different respirator facepiece, including a different make, model, style, or size.
Qualitative vs. quantitative fit testing
Qualitative fit testing is a pass-or-fail method that uses the wearer's senses to detect a test agent. It may be appropriate for certain negative-pressure respirators, depending on the required level of protection.
Quantitative fit testing uses an instrument to measure leakage around the face seal and produces a numerical fit factor. The appropriate method depends on the type of respirator and how it will be used.
Facial hair and the respirator seal
Facial hair cannot interfere with the sealing surface of a tight-fitting respirator or the function of its valves. Even short stubble in the seal area can prevent a reliable fit. Employers should address this requirement before the appointment so workers arrive prepared for testing.
