Face Fit Testing


Face fit testing is a quick and straightforward process all employers should adopt for their employees who need to wear a tight-fitting mask to carry out their duties. Legislation and the Health and Safety Executive (HSE) advise face fit testing, keeping employers compliant and suitably protected against insurance claims and prosecution should any be brought against them. Crucially, however, it is for the safety and comfort of employees working in usually uncomfortable and high-risk areas where masks are necessary - resulting in a more productive and happy workforce. 

This Citrus certification takes delegates through a mask face fit test. It is for anyone needing fitting and testing to safely wear a mask at work.

Course Outline

This certificate is 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. 

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 Certificate.

Course Programme

This training is essential for anyone needing to wear a mask to carry out their work.

The Qualitative Face Fit Session consists of:

  • Responsibilities of the wearer
  • Mask selection
  • Mask inspection

On Completion

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. 

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

It is vital that the mask seals 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 that 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.
