More than ever, with the current outbreak masks are being worn, however we need to make sure the mask is fitted correctly to minimise the risk of transmission.
Respiratory protective equipment
Tight-fitting respirators such as disposable FFP3 masks and reusable half masks rely on having a good seal with the wearer’s face. A face fit test should be carried out to ensure the respiratory protective equipment (RPE) can protect the wearer.
To ensure you put on tight-fitting RPE correctly, use a mirror or ask a colleague. Fit-testers should follow government advice on social distancing, as they can make observations from this distance and deliver any instructions verbally.
The user should then carry out a pre-use seal check or fit check. The video gives guidance on how to put on disposable respirators and how to do a pre-use seal check or fit check.
Minimise the risk of transmission
People who have symptoms of COVID-19 or are isolating in accordance with government guidance should not attend a face fit test.
To minimise the risk of transmission of COVID-19 during face-fit testing the following additional measures should be taken:
- Fit-testers should follow government advice on social distancing;
- Fit-testers can make observations from a distance and deliver any instructions verbally;
- Those being fitted should keep their respirators on;
- If closer observation is required, both the fit tester and those being fit tested should wash their hands before and after the test in accordance with NHS guidelines;
- Those being fit tested with non-disposable masks should clean the mask themselves before and immediately after the test using a suitable disinfectant cleaning wipe. Please check with manufacturer instructions to avoid damage to the mask;
- Test facepieces that cannot be adequately disinfected (e.g. disposable half masks) should not be used by more than one individual;
- Fit testers should wear disposable gloves when undertaking cleaning of the tubes, hoods etc and ensure they remove gloves immediately dispose of used gloves, disposable masks, cleaning wipes etc in a waste bin. Follow the correct procedure from HSE https://www.hse.gov.uk/skin/posters/glovesingleuse.pdf
A fit test should be carried out before people wear Respiratory protective equipment (RPE) for the first time. Inadequate fit can reduce the protection provided and lead to immediate or long-term ill-health or can even put the RPE wearer’s life in danger.
General points to note
A fit test should be repeated whenever there is a change to the RPE type, size, model or material or whenever there is a change to the circumstances of the wearer that could alter the fit of the RPE; for example:
- Weight loss or gain
- Substantial dental work
- Any facial changes (scars, moles, effects of ageing etc) around the face seal area
- Facial piercings
- Introduction or change in other head-worn personal protective equipment (PPE)
There is no stipulated frequency for re-testing, and you don’t need one if there are no changes in these circumstances.
