Wearing a properly fitted respirator is essential for protecting workers from airborne hazards, dust, particles and other workplace contaminants. However, not every respirator provides an effective seal for every wearer. If you fail an N95 or P2 mask fit test, it is important to understand why it happened and what steps you should take next.

A failed mask fit testing N95 assessment does not necessarily mean you cannot wear a respirator. It indicates that the selected mask has not demonstrated an adequate seal and that an alternative solution is required before relying on it for respiratory protection.

1. Understand Why You Failed the Mask Fit Test

Several factors can contribute to a failed mask fitting test. These include choosing the wrong respirator size, incorrect positioning, damaged straps, facial hair interfering with the seal or failing to adjust the nosepiece correctly.

Even small gaps around the nose, cheeks or chin can allow contaminated air to enter. Understanding the reason for failure helps identify the most appropriate corrective action.

2. Check Your Respirator and Wearing Technique

Before trying another respirator, check whether you are wearing the mask correctly. Follow the manufacturer's instructions, adjust the straps and mould the nosepiece securely.

Ensure the respirator is not damaged, stretched or incorrectly positioned. Perform a user seal check every time you put on your respirator, as recommended by the manufacturer. Remember that a user seal check does not replace a formal fit test.

3. Try a Different Respirator Model or Size

If your current N95 or P2 mask does not provide an adequate seal, consider an alternative model, size or design. Different respirators fit different facial shapes, so trying another approved respirator may help achieve a better seal.

A new mask fit test must be completed successfully with the alternative respirator before it is used as your designated respiratory protection.

4. Arrange Another Mask Fit Testing Assessment

Once you have identified a suitable alternative, arrange another professional assessment. Depending on the respirator and applicable workplace requirements, qualitative or quantitative fit testing may be appropriate.

Successful mask fit testing should be documented, including the respirator make, model, style and size tested. Workers should also understand when retesting is necessary, such as when their facial characteristics change or workplace requirements demand it.

5. Obtain Your Mask Fit Testing Certificate

After successfully completing the assessment, workers should receive appropriate documentation. A mask fit testing certificate or mask fit test certificate provides a record of the successful assessment and identifies the specific respirator tested. Keep this documentation accessible for workplace compliance and future reference.
