“Respirator comfort is an important factor in wearer acceptance. Respirators with greater wearer acceptance are more likely to be worn appropriately.” — CAN/CSA-Z94.4-18

As stated in the CAN/CSA-Z94.4, it is now required that employers ensure that their workers’ comfort is considered when selecting respiratory protection.
In the 30 years that I’ve been working in the safety industry, this one’s a first; a first to see a national safety board formally recognize the importance of comfort and a first for holding employers responsible for seeing that this comfort is met.

Now, personal preferences on breathing resistance, impairment of vision, impairment of communications and respirator weight are all to be evaluated during respiratory fit tests.

What does the new comfort assessment entail?

Under the “records of respirator fit testing” section (14.4), the Standard states that individuals being fit tested for respirators must help assess its comfort and appropriateness and see that the following criteria is met:
a) Proper placement of the chin in its resting space;
b) Proper fit and position of the facepiece on the nose (if it is a half-facepiece) or nose cup on the nose (if it is a full-facepiece);
c) Position of the eyes within the facepiece lens to allow the best peripheral vision (if a full-facepiece);
d) Optimal strap tension (not too loose or too tight) and positioning;
e) Accommodation of spectacles (lens inserts in a full-facepiece) or eye protection (with a half-facepiece), without adversely affecting face-to-facepiece seal;
f) Intelligible speech without an obvious break in the face-to-facepiece seal;
g) Stability, against tendency for a facepiece to slip, create excessive pressure or break the seal, for example in the presence of movement or contact with other integrating PPE or accessories;
h) Full contact of the sealing surface of the facepiece to the face;
i) Proper positioning of additional integrating equipment (i.e., PPE) for function;
k) Successful seal check, followed by:
       i. Sufficient time allowed (at least 5 min) for assessment of comfort in relation to the face-to-facepiece seal, strap tension, or other pressure points resulting from integrating PPE if worn, including corrective lens inserts, safety glasses, hoods, helmets, etc.; and subsequently
     ii. the wearer’s verbal confirmation of adequate comfort; and
k) Repeated successful user seal check.

The Advantages

Including “comfort” as a formal consideration in selecting the right respiratory protection means that workers’ comfortability is being taken seriously; the more comfortable a worker is in their protective equipment, the more likely they will be compliant in wearing it.
Introducing the comfort clause ensures that workers are able to focus on the job at hand rather than the distraction of uncomfortable PPE. It is hoped that this addition will lead to more positive attitudes towards wearing the required equipment as well as more positive safety cultures amongst workplaces.

The Disadvantages

Despite all the benefits of worker compliance, including this new component into the fit-testing process means that more time will be spent evaluating each worker than before. Prior to when this clause was initiated, quantitative fit testing alone was a quick and easy solution to finding the right fit for each worker. Now, in addition to the previous process, each fit tester must go through all of the criteria listed above and wear the respirator for at least five minutes to ensure their comfort is being met.
Lastly, remember that managers are now accountable for not only providing compliant, but “comfortable” respirators for each worker – which in itself is quite subjective. The onus is on every place of employment to be providing respirators that meet each worker’s unique expectations of comfort.

The Solution

Luckily, Honeywell respiratory protection products make the challenge of meeting each worker’s comfort easy and achievable. Honeywell has been a big player in the respiratory protection game for a number of years – and for good reason. Their quality respiratory product lineup has solutions that meet every workplaces’ needs whether it’s for high risk industry or healthcare.
Features such as their triple-flange design and hundred per cent medical-grade silicone make their respirators comfortable while ensuring that every worker is secured from respiratory hazards.

What does this new clause mean for the future of respiratory protection? In short, we’ll be seeing both advantages (for the worker) and disadvantages (for the employer). But, despite whatever challenges may come as a result, this new addition to the standard is a step in the right direction for safety’s sake.
