FREQUENTLY ASKED QUESTIONS
01: Why do we need to undertake a face fit test?
An ill-fitting mask or a mask that has been put on incorrectly can leave small gaps between the face and respirator reducing protection. A face fit test will ensure that the correct mask & advice is provided & the full protection is afforded for the wearer.
A correct fitting mask is vital to prevent exposure to dangerous hazards.
02: Are all masks required to be face fitted?
All tight face fitting masks such as disposable masks (FFP Masks) (EN 149) as well as reusable half masks (EN 140)& Full Face Masks (EN 136) are required to be face fitted by the employer.
There is a legal requirement that all employees should be face fitted if wearing any tight face fitting masks such as FFP dust masks (EN 149) (including FFP1, FFP2 & FFP3 Dust Masks), reusable half masks (EN140) & Full Face Masks (EN136).
Powered Air Purifying Respirators (PAPR) (EN12941) and compressed air units (EN139 & (EN270) are not required to be face fitted.
03: What Respiratory Face Fit Testing is required?
There are two methods of face fit testing available for Disposable masks, Reusable Half Masks & Full Face masks:
• Qualitative fit testing
Approved by the HSE, Qualitative face fit testing is a simple 20 minutes subjective assessment of leakage, incorporating a face fit test hood & strong tasting / smelling solutions using a nebuliser.
If the wearer cannot taste or smell the additives an adequate facial seal has been shown. This test can be carried out by a competent person trained to HSE standard.
Applicable Masks:
Disposable Dust Masks
Reusable Half Masks
• Quantitative fit testing
Quantitative face fit testing is a far more accurate test measuring the level of particles both within & outside the mask creating a fit factor ratio. The higher the fit factor the better the seal.
Applicable Masks:
Disposable Dust Masks
Reusable Half Masks
Full Face Masks
04: What could make a face fit test Fail?
All testing must be undertaken on a clean shaven face. Outstanding facial features including facial hair, scars & jewellery can all prevent an adequate seal between mask & face being achieved.
The results of the taste test could also be compromised if the wearer has impaired taste of smell or is a smoker. (Must not smoke for 24hrs)
