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.
Before fit testing or required respirator use, the employee must first receive a medical evaluation to determine whether they can safely wear the respirator. Fit testing is one part of a complete respiratory protection program that also includes hazard assessment, respirator selection, training, inspection, maintenance, and recordkeeping.
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.
Retesting may be necessary sooner if physical changes could affect the seal. Examples include significant weight change, dental work, facial surgery, scarring, or other changes in facial structure. A worker who reports that the respirator no longer fits correctly should be evaluated rather than waiting for the annual test.
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.
Help your appointment go smoothly
- Bring the exact respirator make, model, style, and size used at work.
- Complete the required medical evaluation before fit testing.
- Be clean-shaven anywhere the respirator contacts the face.
- Bring corrective lenses or other PPE worn with the respirator.
- Tell the tester about any recent physical changes affecting fit.
