Qualitative Respirator fit testing (QLFT)
What is it?
Fit testing can be performed using a Qualitative fit test (smell or taste test) and is a method of checking that a tight-fitting respirator/mask matches the wearers facial features and seals adequately to their face.
The QLFT is used for half face tight fitting respirators including disposable (N95 & other masks) or reusable respirators with filters or cartridges.
To ensure individuals are provided with the correct model and size fit testing should be completed prior to the individual starting in their role.
What is included?
The Qualitative fit testing includes the following:
- Teaching the individual how to don & doff the respirator correctly
- Provide information and training on how to disassemble the reusable respirator for cleaning and maintenance purposes & correct storage
- Information on when to change filters; particulate, gas & vapour filters
Who is it for?
Respirator fit testing is for all workers who are exposed to airborne substances such as dust, mist, vapours and gases (e.g. wood dust, welding fumes, solvent vapours) and are required to wear respiratory protection.
Frequently Asked Questions
Respirator fit testing shows your business has taken all reasonable and practicle steps to prevent your staff from having any exposure to respiratory health hazards at your workplace.
Not all respirators fit all faceshapes and therefore the fit test confirms that the respirator used provides a good seal between your employees face and the respirator.
Respirator fit testing should be part of the induction process prior to starting work, and should be completed every 12 months thereafter.
Fit testing may need to be completed sooner in certain instances:
– If the faceshape of the individual changes, for example, due to: weight gain/loss of
more than 10kgs, removal of teeth, any injury resulting in a scar.
– If they are using a different respirator.
A full face beard is a problem when it comes to wearing a tight fitting respirator, as it is difficult to achieve a good seal between the wearer’s skin and respirator. Qualified fit testers should not perform a fit test in this situation.
There are some options you can explore to overcome this problem:
– Educate your staff on the respiratory hazards and the effects this could have on their health
– Define beard styles that are acceptable when wearing a respirator. Write this
requirement into the individual’s employment contract.
– Use an airfed hood, which do not require any fit testing, if your employees still opt to
have a full face beard.
As the employer, it is your responsibility to ensure your staff are protected. Here is a guide
of which facial hairstyles can work with respirator masks.
