Qualitative Face Fit Testing

When tight-fitting respiratory protective equipment (RPE) is used, employers must ensure it provides an effective seal for each wearer. An ill-fitting mask can allow hazardous dusts to bypass the filter, leaving workers at risk of ill-health, and businesses at risk of non-compliance.

At Immerse Safety, we provide qualitative face fit testing to confirm that a wearer’s chosen RPE is suitable and provides a tight seal.

Why face fit testing matters

  1. Legal Compliance – A legal requirement under COSHH where tight-fitting RPE is used.
  2. Worker Protection – Ensures seals provide the level of protection they were designed to deliver.
  3. Avoid Costly Enforcement – Reduce the risk of HSE enforcement, notices, fines and prosecution.
  4. Protect Your Business – Minimise sickness absence, project disruption, compensation claims and reputational damage.
  5. Protect Lives – Prevent exposure to hazardous substances that can cause life-changing or fatal occupational disease

Our Service:

We carry out qualitative face fit testing in accordance with INDG479 guidance, using a recognised fit test protocol.

  • On-site testing available for 6+ workers
  • Individual appointments available at our office
  • Experienced and competent testers
  • Clear pass/fail reporting and guidance
  • Each wearer must bring their own mask – the exact make, model and size they will use operationally
  • Mask make, model and size must be confirmed at the time of booking
  • No food or drink (other than water) within 30 minutes of testing
  • No smoking or vaping within 30 minutes of testing
  • Wearers must be clean-shaven in the mask seal area
  • Any additional PPE worn alongside the RPE (including hearing protection, prescription glasses or safety eyewear) must be worn during the test
  • Wearers must be able to correctly don their mask independently and demonstrate this to the tester before testing begins

Failed Tests:

A failed test does not necessarily mean there is a fault with the mask. It may indicate that the selected RPE is not suitable for the individual’s facial profile. In either case, we’ll advise on next steps.

Please note:

  • Failed tests remain chargeable
  • Re-testing and alternative mask selection may be required
  • Additional charges apply for repeat tests

Face Fit Testing does not remove the employer’s legal duties under:

  • the Health and Safety at Work etc. Act 1974,
  • the Management of Health and Safety at Work Regulations 1999, and
  • the Control of Substances Hazardous to Health Regulations 2002 (COSHH), including duties relating to suitable RPE selection, maintenance, training, supervision and exposure control.
