Respirator Fit Testing

Do you have workers who wear tight fitting respirators (those that rely on a seal with the face) such as Disposable, Half Mask or Full Face Masks (including those fitted to a powered respirator)? If so, you are required to fit test them.

What is Fit Testing?

Fit testing is a means of checking that a respirator facepiece matches a person’s facial features and seals adequately to their face. There are several methods available and the Health and Safety Executive’s information document HSE 282/28 provides information on how the HSE expect fit testing to be conducted.

The performance of tight fitting respirators relies on achieving a good seal between the facepiece of the respirator and the wearer’s face. If the seal is inadequate, contaminated air will take the path of least resistance and will travel through leaks in the face seal. Consequently, a poor seal to the face will reduce the level of protection provided to the wearer.


3M Fit Testing Services

3M offer both Qualitative and Quantitative Fit Testing.

The 3M Fit Testing Service is provided by Fit2Fit accredited personnel on the employers site at a day/time suitable to the employer. The Fit2Fit accreditation scheme is a BSIF initiative supported by the HSE which ensures fit testers can conduct a fit test to the level of competence required in the HSE guidance note 282/28. Fit testing will be conducted in a professional and friendly manner which is important when coaching and reassuring employees.

We will fit test employees on the respirator that has been issued. We also carry sufficient samples of 3M’s alternative respirators, so should any employee require a different model or design, samples are made available.

    Each fit test includes:
  • Brief explanation of need for fit testing
  • Explanation of fit test procedure
  • Coaching on getting best fit with the Respiratory Protective Equipment in use
  • Fit test
  • Certificate of fit test and written set of results

3M offer both half a day for up to 8 people, and a full day for up to 17 people, depending on the number of employees who require a fit test.
