Respirator fit testing

Testing frequency

Respirator fit testing should be completed:

• Whenever a worker starts using a respirator
• On an annual basis (or sooner if there is a significant change in the wearer’s facial characteristics)

Testing types

There are two types of respirator fit tests:

• Quantitative fit testing (QNFT) for full-face and half-face respirators
• Qualitative fit testing (QLFT) for half-face respirators only

In addition to providing both quantitative fit testing and qualitative fit testing, our experienced team also provides education and training on storing, cleaning, maintaining and the correct use of respirators.

Quantitative respirator fit testing

Quantitative fit testing (QNFT) uses a machine to measure the leakage around the face seal and produces a numerical result called a “fit factor”. This comprehensive method provides a numerical result and report for analysis.

This test method can be used on all respirators (full-face reusable, half-face reusable and disposable).

Qualitative respirator fit testing

Qualitative fit testing (QLFT) uses a hood and testing agents (Bitrex or Saccharin) and relies on the users ability to taste or smell a test agent resulting in a pass or fail.

This test method can only be used on half-face respirators (reusable and disposable).
