Respiratory protection

Face fit testing

The only HSE-recognised way to be sure a tight-fitting mask actually protects the person wearing it. We test at your site or at our head office in Rochdale.

What is face fit testing?

Make sure the mask really protects

The HSE recognises face fit testing as the only way to confirm that respiratory protective equipment (RPE) properly protects the wearer. A poor seal can let harmful dust, fumes, chemicals or bacteria past the mask, risking serious ill health and enforcement action against the business.

A fit test certificate applies only to that person and that specific make and model of mask. If the mask changes, a new test is needed.

How does it work?

How we fit test

We use qualitative fit testing, the recognised method for disposable filtering facepieces and reusable half masks.

Qualitative

A pass or fail check

The wearer puts on a hood and we release a bitter or sweet test solution. If they can taste it, the mask isn't sealing and the test fails. This method is used for disposable filtering facepieces and reusable half masks.

What's involved?

The face fit testing process

It's straightforward. Wearing your mask, you'll carry out a series of simple movements, similar to those you'd do at work. We use the qualitative (hood and solution) method to check the seal.

To pass, the mask must reach the required level of protection. If it doesn't, the tester will explain why and help recommend a better-fitting alternative.

Protecting everyone

Which masks need a fit test?

Any tight-fitting mask worn to protect against harmful substances must be fit tested.

Needs a fit test

Tight-fitting RPE

Disposable filtering facepieces (FFP2 / FFP3), reusable half masks and full-face masks all form a seal against the skin and must be fit tested to the individual.

Exception

Loose-fitting masks

Loose-fitting RPE and disposable surgical-type masks, such as those used to reduce the spread of COVID-19, don't rely on a face seal and don't require a fit test.

The law & who it applies to

When fit testing is required

If employees are exposed to harmful substances you must provide suitable RPE, and in most cases arrange face fit testing, under:

  • Control of Substances Hazardous to Health Regulations 2002 (COSHH)
  • Control of Lead at Work Regulations 2002
  • Control of Asbestos Regulations 2012

Once mainly used in construction, manufacturing and laboratories, fit testing is now common across many sectors:

Facial hair guidance

You must be clean-shaven

A tight-fitting mask can only seal against clean-shaven skin. Stubble, a beard or any facial hair breaks the seal and lets unfiltered air through, so we can only fit test people who are clean-shaven on the day.

Anyone who wears tight-fitting RPE must stay clean-shaven whenever it's worn. If that isn't practical, ask us about loose-fitting masks or powered hoods as an alternative.
