What is respirator fit testing?

Respirator fit testing is a medical evaluation that measures whether a respirator properly fits an individual’s face and provides adequate protection against airborne hazards. Wearing a tight-fitting respirator requires a fit test. Depending on the respirator type, the method of fit testing will differ.

Which fit testing method is right for me?

The fit testing method is based on the type of respirator your employees wear. All NIOSH-approved tight-fitting half-face masks are most commonly tested using qualitative fit testing, but can also be tested quantitatively. All tight-fitting full-face masks require quantitative fit testing.

What happens prior to a fit test?

Your employees must come to their fit test clean shaven, and must not eat, drink, or smoke within 15 minutes of their fit test. All employees must complete and pass an OSHA medical evaluation prior to the test, as part of your respiratory protection program.  

What happens during a fit test?

In a qualitative fit test, a Mobile Health clinician will first establish the user’s sensitivity to a threshold solution. The patient will then don their respirator and be exposed to a higher concentration of the same solution. If the user does not taste the second solution, they will then pass the test.

In a quantitative fit test, the seal and fit of the user’s respirator is tested by a machine, which measures the amount of the particles from the testing agent that are able to enter the mask. This is known as ‘fit factor’ and determines whether the respirator provides sufficient protection.

Who needs a respirator fit test?

Any employee required to wear a tight-fitting respirator must have a fit test prior to their employment, and once annually. Industries requiring respirator fit testing include:

  • Healthcare
  • Construction
  • Agriculture
  • Mining
  • Chemical application
  • Natural gas
  • Medical education
  • Emergency response
  • Asbestos abatement

If employers are not compliant with OSHA’s respiratory protection standard, there is a minimum fine of $15,625 per violation.

Do I also need a Respiratory Protection Plan?

Yes, every employer who falls under OSHA’s respiratory protection standard is also required to create and maintain a respiratory protection program. There are 7 elements every plan must address:

  1. Respirator selection
  2. Medical evaluations
  3. Use of respirators
  4. Maintenance and care
  5. Assuring adequate air quality
  6. Training and fit testing
  7. Program evaluation

“Which type of respirator fit testing should I use?” Fit testing depends on your industry, workplace hazards, and the type of masks your employees wear! A great rule of thumb, ALL full-face masks require quantitative fit tests. For half-face respirators like N95s and EHMRs, you can perform qualitative or quantitative fit testing. Our respiratory protection experts can help you determine which solution is best for you!
