Respirator Fit Testing & Clearance | Why Is It Required?

If you are in a job that requires you to wear a respirator, then it is important for you to know about respirator fit testing by VestMed Services. Fit testing is the process of finding out if your respirator fits properly and protects against certain hazards.

Respirator Clearance

Respirator clearance is important because it determines that the mask you have on is actually protecting you from particles in the air. This testing ensures a good fit of your respirator and it should be done before each use of a tight-fitting facepiece, which includes dust masks, disposable respirators, or half-face models with cartridges/filters.

It helps to ensure there are no leaks around the edges of the mask, so contaminants don't enter between these areas instead of where they're supposed to go. Fit testing can also help prevent respiratory health issues such as bronchitis or emphysema.

How to Perform a Respirator Fit Test

A respirator clearance is performed by having the person wear a respirator for at least 15 minutes while performing normal job tasks. The test is considered successful if no leaks are detected and the fit factor equals or exceeds 100. A fit factor of 1000 means there were no detectable leaks, which would provide you with maximum protection from contaminants in the air.

Check for Proper Fit

One of the most important things to remember when testing a mask is to avoid damaging it by pulling on straps, rubbing it with your hands, or putting it on too quickly without first checking for proper fit. If they're not cleaned and stored properly, any kind of rubber can break down over time, so be sure to follow the manufacturer's directions closely in terms of how often masks need regular care and what should be done about repairs, etc.

Tips for Choosing the Right Mask Based on Your Needs

Choosing the right mask is important if you want your workers to be protected from hazardous exposures in the workplace. There are certain factors you need to consider when choosing a mask, such as its fit and comfort level on your face. You also want to make sure that it is easy to use with safety equipment like gloves or other personal protective equipment (PPE).


Respirator fit and lung function testing ensure that your mask is doing its job of protecting you from hazardous exposures in the workplace. If a respirator does not have a good seal against your face, then it will be much less effective at keeping out harmful airborne chemicals, particles, or gases. Without proper protection, workers can suffer health problems as a result of their exposure to these hazards.
