A fit test is used to determine which respirator properly conforms to your face, ensuring a seal that minimizes exposure to contaminant leakage through the faceplate. This process involves the use of a testing agent, which can be detected either through the wearer’s sense of smell or an involuntary cough reaction to irritant smoke, or measured with specialized equipment to confirm the mask’s fit.

The Occupational Safety and Health Administration (OSHA) requires that individuals using a tight-fitting respirator in the workplace undergo and pass a fit test before use.

If there are gaps around the edges of the mask, unfiltered air can bypass the mask and enter your lungs. To prevent this, always check that your mask is positioned correctly and sealed properly each time you wear it. Keep in mind that facial hair, including beards and stubble, can prevent a secure seal from forming. If you are unsure if your current mask fits properly, it is best to get a fit test.

A fit test is required before wearing a tight-fitting respirator, such as an N95, for the first time. After that, testing must be repeated at least annually or sooner if you experience significant changes in weight or facial structure. If you change jobs or switch to a different respirator model, a new fit test is also required.

To ensure accurate results, avoid eating, drinking (except water), smoking, or chewing gum for at least 15 minutes before your test. Additionally, you must be clean-shaven in the areas where the mask seals to your face to achieve a proper fit. Take off jewelry that can get in the way of the mask seal.

No. Your fit test is only valid for the exact brand, model, and size of respirator that you were tested with. Since different manufacturers design their masks differently, a fit test does not guarantee a proper seal with other respirators. Levac Safety mask fit testers will help youfind the perfect mask that optimizes safety and comfort.

Since you were fit-tested with a specific mask, you cannot use any other model because you are not certain it provides the same fit and protection required.

It is entirely possible that an instant failure can occur at any time due to a variety of reasons which would end the test prematurely. There are a number of reasons you could fail the test: The respiratory mask being tested doesn't provide an adequate seal around your face, incorrect size, model or style provided. In the case of a failed fit test, you will need to try a different model/style of respirator until one successfully fits.

The fit testing process typically takes between 15 and 20 minutes.

Yes, you can generally undergo a mask fittest if you are pregnant, as the solutions used in the testing process are generally considered safe. However, you should closely monitor the fit of your mask during and after pregnancy to ensure no significant changes to face shape has occurred.
