Face Fit Testing - Train the Tester


While face fit testing is a quick and straightforward process, it is governed by strict regulations and legislation. They and the Health and Safety Executive (HSE) advise face fit testing to keep employers compliant and suitably protected against insurance claims and prosecution should any be brought against them. Crucially, however, regulations and procedures ensure employees' safety and comfort working in usually uncomfortable and high-risk areas where masks are necessary - resulting in a more productive and healthy workforce. 

This Citrus certification ensures delegates are competent to carry out face fit testing of their employees, understand the legislative and procedural requirements in testing, record results and know when not to test an employee.

Train the Tester provides more efficiency and cost-effectiveness to large companies that may have high staff volumes that require face fit testing to work in their role safely. 

Course Outline

This course will instruct the candidates on the legislative and practical requirements to allow them to face fit test their colleagues and employees. 

As part of the course, all candidates will undertake a face fit test procedure on each other to demonstrate understanding of the correct process, as highlighted in INDG 479. This process consists of a simple pass or fail test based on the wearer’s assessment of face seal leakage, using their sense of taste of a test agent (bitter or sweet). In addition, they’ll participate in mask selection, inspection, correct fitting and care and maintenance activities and advice during the session. Finally, they will examine the importance and implications of proper reporting and retesting requirements.

The course reflects national standards and industry best practices and is fully accredited in line with regulations. In addition, choose to learn with Citrus, and delegates will benefit from our custom-built training facilities and customer-first approach.

Our occupationally and technically experienced trainers take delegates through the test completing the session with a pass-or-fail assessment. They must pass the test to qualify for the Citrus Face Fit Tester Certificate.

Things You Need to Know

Face fit testing is for any worker who wears a tight-fitting mask to prevent illness as part of their role.

Delegates must be cleanly shaven. Anyone that is not shaved to the skin will not be tested – There are no exceptions to this rule.

Delegates must not eat, smoke, or drink anything other than still unflavoured water for a minimum of 30 minutes before their test. Doing so can inhibit their detection of the test substance. 

All delegates on the Train the Tester course undergo a face fit test as part of their training, hence the need to comply with the criteria above. 

For training held at your location, please ensure that the classroom you make available has a 240v power supply and is a suitable size for the number of delegates attending. In addition, please ensure that the practical area has been risk-assessed, is free from harm, and is ideal for training. 

Popular FAQ's

The mask must seal directly to the wearer’s skin to prove effective. INDG 479, Guidance for Face Fit Testing, states this as a requirement and full compliance with the guidance is considered a suitable defence for compliance. 

All tight-fitting masks require a test, whether full-face or half-face.

This test only covers the use of disposable and reusable filter half masks. These will be marked generally as FFP2 or FFP3. 

No. A face fit certificate only applies to the wearer's size, make and model of the mask used on the test. 

They can use new masks of identical size, make, and model but any other mask will require a fresh face fit test.

No. As these items are not ‘tight fitting’, they will not require a face fit certificate. However, the employer will still have a duty to train the employee and ensure the equipment is suitable to the wearer and task.

In such a scenario, the candidate cannot be face fit tested due to not being cleanly shaven. However, they are still required to be protected, so the employer would need to look at hood or air feed mask options.

INDG 479 states that employees should retest at intervals identified following a risk assessment. 

 The more exposure a wearer gets, the more often they should be retested, with most companies working on an annual retest as a minimum.

Other occasions requiring retesting are: 

  • Changes to make or model of mask
  • Following major dental work or following significant facial surgery to the wearer
  • Following significant weight gain/loss by the wearer
  • Following any incident where a wearer has picked up a health issue due to work requiring a tight-fitting mask being the cause.
