Do I need a Face Fit Test if I use RPE?

If you or your employees are required to use dust masks, or any other form of Respiratory Protective Equipment (RPE), you’ve probably asked: “Do I really need a Face Fit Test?”.

The answer is a clear and simple YES.

Even today, thousands of people lose their lives each year due to exposure to hazardous airborne substances in the workplace. Many of these deaths could be prevented with one critical step: ensuring their RPE actually fits properly.

It’s Not Enough Just to Wear a Mask

Kentec Training's Managing Director & long-standing RPE instructor and fit-tester, Steve Booker, had this to say:

One of the biggest issues with improperly-fitted RPE is the cumulative effect of repeated and short-term exposures to harmful substances and particulates which can lead to long-term health issues. Employers have a legal, financial and moral responsibility to their employees to ensure that they are protected regardless of the duration of the work or simplicity of the task.

As Steve stated, employers have a legal duty to make sure RPE is suitable for the wearer. That doesn’t just mean the right type of mask - it means the right fit. You can invest in the highest-grade RPE on the market, but if it doesn’t create a proper seal on the wearer’s face, it simply won’t protect them.

A Fit Test will ensure that the mask:

  • Fits the individual’s facial features
  • Creates a tight seal around the mouth & nose
  • Works as intended to filter harmful substances & particles.

This applies to all tight-fitting respirators, including disposable masks (FFPs), half masks and full-face masks. Loose-fitting RPE like powered hoods and visors don’t need a face fit test - but they still need to be worn correctly and with proper training.

Legal Backing

Face Fit Testing is not just best practice - it’s a legal requirement under:

Why Must I Be Clean-Shaven?

A proper seal simply can’t be formed over facial hair. Even stubble can create tiny gaps. That’s why individuals being tested must be clean-shaven in the sealing area. Some employers even include this in employment contracts when RPE is part of the job.

For those who can’t shave for religious or medical reasons, alternative RPE is available - such as powered air systems with loose-fitting hoods that don’t require a tight seal.

How Often Should You Be Tested?

It’s recommended to re-test at least annually, especially when RPE is a primary control method. Retesting is also needed if the wearer:

  • Has significant gains or losses in weight
  • Grows facial hair (including stubble)
  • Makes changes to the Mask's model, size, or replaces their mask.
  • Has had significant dental or facial changes
