Face Fit Testing
Central Scotland
On-site face fit testing for tight-fitting respirators and FFP masks. Qualified testers, certificated results, available across Central Scotland and Lanarkshire.
What is face fit testing?
A face fit test checks whether a specific make and model of tight-fitting respiratory protective equipment (RPE) forms an adequate seal against an individual's face. No two faces are the same, and a mask that fits one person well may leak badly on another — even if it's the correct size.
The test is carried out for each person, for each specific mask they use. If a wearer changes to a different make or model, or if there are significant changes to their face — weight loss, dental work, facial scarring — the test needs to be repeated.
The requirement comes from the Control of Substances Hazardous to Health Regulations 2002 (COSHH) and is reinforced by HSE guidance. Employers who issue tight-fitting RPE without evidence of a passing face fit test are not complying with the law.
Tight-fitting masks — testing required
FFP2 and FFP3 disposable masks, half-face respirators, full-face respirators, powered air purifying respirators (PAPRs) with tight-fitting facepieces.
Loose-fitting hoods — no test needed
Powered air purifying respirators with loose-fitting hoods or helmets do not require face fit testing, though they must still be selected and maintained correctly.
The two methods
There are two recognised methods of face fit testing. We carry out both.
A pass/fail test based on the wearer's sense of taste or smell. A bitter or sweet aerosol is introduced around the mask while the wearer performs a series of set exercises. If they detect the substance, the mask is not sealing correctly. Suitable for disposable FFP2 and FFP3 masks and half-face respirators. Straightforward, quick, and the most common method for most workplaces.
Uses equipment to measure actual leakage into the mask, giving a numerical fit factor result. Does not rely on the wearer's senses. Required for full-face respirators and recommended where a higher level of assurance is needed. Takes slightly longer per person than qualitative testing.
What happens on a face fit test visit
-
Pre-test check We confirm the make, model, and size of mask being used. If a wearer has been using a mask that isn't suitable for their face shape, we'll identify this before testing begins.
-
Sensitivity check (qualitative only) The wearer is checked for their ability to detect the test agent. Anyone who cannot detect it cannot be qualitatively tested and would need quantitative testing instead.
-
Donning the mask The wearer puts the mask on as they normally would. We observe and correct technique where needed — poor donning is one of the most common reasons for a failed test.
-
Exercises The wearer performs a set of standard exercises — normal breathing, deep breathing, head movement, talking, bending — while wearing the mask. These replicate the range of movements that occur during typical work tasks.
-
Result and certificate A pass or fail is recorded. Every person who passes receives a face fit test certificate showing their name, the mask make and model, the method used, and the date. These records are held on file.
Who needs face fit testing
Any worker who wears tight-fitting RPE as part of their work. This includes but is not limited to:
Records and certificates
Every completed test is documented. We provide each tested individual with a face fit test certificate, and a full record of the visit is kept on file for your site. The table below shows what is recorded.
| What is recorded | Detail |
|---|---|
| Wearer's full name | As provided on the day |
| Mask make, model and size | Exact product reference |
| Test method used | Qualitative or quantitative |
| Test agent used | Bitter or sweet (qualitative) |
| Exercises completed | Full standard set per HSE guidance |
| Result | Pass or fail |
| Date of test | For review and repeat scheduling |
| Tester name and qualification | Recorded on each certificate |
HSE guidance recommends face fit tests are repeated when the wearer changes mask make or model, when there are significant changes to facial features, and as a general rule every two to three years. We can help you set up a schedule and remind you when retests are due.

Frequently asked questions
How long does each test take?
A qualitative test typically takes around 20 to 30 minutes per person including the sensitivity check, exercises, and paperwork. Quantitative testing takes slightly longer. For group visits we'll give you a realistic time estimate based on the number of people being tested.
Do people need to bring anything?
They should bring the exact mask they use for work — the specific make, model, and size. Testing is done on the mask the individual will actually be wearing, not a generic sample. If you're not sure which masks your team should be using, we can advise on that as part of the visit.
What if someone fails?
A fail usually means either the mask doesn't suit that person's face shape, or it wasn't being worn correctly. We'll work through the reason and, where possible, retest with a different size or alternative model. A fail on one mask doesn't mean the person can't be tested successfully on another.
Can you test large groups in one visit?
Yes. We can schedule a full-day visit for larger teams. Get in touch with the number of people you need tested and we'll confirm what's involved.
Do you supply the masks as well?
Yes. As a PPE supplier with over 30 years in the trade, we stock a full range of FFP2, FFP3, and half-face respirators. If you need to switch masks or trial an alternative make, we can supply direct.
How often does face fit testing need to be repeated?
HSE guidance says testing should be repeated if the wearer changes to a different make or model of mask, if there are changes to the wearer's facial features (significant weight change, facial surgery, new dentures), or as part of a regular review — typically every two to three years.
