Qualitative face fit testing
Red One provides both Quantitative and Qualitative face fit testing to ensure your team’s respiratory protective equipment (RPE) offers the protection required by law.
Under HSE legislation INDG479, all RPE must provide an adequate seal and level of protection for the wearer. If your staff use tight-fitting facepieces in the workplace, you are legally required to provide evidence of a face fit test for each make, model, and size of mask they use.
What is a Tight-Fitting Facepiece?
Tight-fitting facepieces include:
- Disposable Filtering Facepieces (FFP1, FFP2, FFP3)
- Half Masks
- Full Face Masks
Quantitative vs. Qualitative Testing
Quantitative vs. Qualitative Testing
Quantitative Testing – This method can be used for all types of tight-fitting facepieces (disposable, half, and full-face masks). It uses a Portacount machine to measure the concentration of particles inside and outside the mask, generating a numerical result known as a Fit Factor. During the test, the wearer performs a series of exercises designed to simulate typical workplace movements, including reading aloud, to ensure the mask maintains an effective seal.
Qualitative Testing
Used only for disposable and half face masks, this method relies on the wearer’s ability to taste a test agent (bitter or sweet). The process involves two stages:
- Sensitivity Test – Confirms the wearer can detect the test agent.
- Fit Test – A series of physical exercises and movements to check if the mask maintains a secure seal during use.
What does the test involve?
- Face fit testing includes a sequence of exercises designed to replicate real-world usage and facial movements:
- Normal breathing
- Deep breathing
- Moving head side to side
- Moving head up and down
- Bending over
- Speaking aloud (reading a passage)
- Returning to normal breathing
