Whether you have a drywall hanger who started cultivating a bushy beard before ZZ Top made it into the Rock and Roll Hall of Fame or your welder is determined to push stubble style intothings can get hairy fast when a respirator is needed. To work effectively, tight-fitting respirators require a secure seal around the face. And we mean tight; even a day or two of stubble can be enough for some guys to render the seal ineffective.
Did you know that facial hair in the sealing surface of a respirator can allow contaminants to leak into the mask? Human hair is much larger in diameter than particles such as dust, smoke, mould and diesel particulate that could cause adverse health effects. This means if the respirator masks seals against human hair, there is ample space between the skin and the hair for particles to infiltrate the mask.

Some of them are long and thin, some are bony and angular, some are round and fleshy… and even the most promising faces still have that troublesome thing sticking out the front that we call a nose. Even a tiny leak around the edge will let hazardous air bypass the filter, leaving you exposed to who-knows-what. In my experience, there are three main reasons why a mask fails to fit properly:.
Simply put Mask Fit Testing and Training is required by both the employers you work with and the Ontario laws that require employers and employees to understand the importance of personal protective equipment PPE. The most common industry where N95 respirators are used is the healthcare industry, where people are often exposed to outbreaks of various kinds. In these environments, it is critical that anyone who is working there know what size respirator they are Fit Tested for and more importantly how to put on Donntake off Doff and create a "Facial Seal" with the respirators.
Studies have shown that facial hair in the face seal zone can increase penetration and decrease the fit factor FFalthough the relationship between the amount and characteristics of facial hair and the increase in penetration is not well quantified. This article examines the influence of facial hair length, areal density, and coarseness on FF for one model of half-face elastomeric negative-pressure air purifying respirator. Three fit tests were performed at each of the 5 lengths, for total tests.
We come across so many different questions from our customers when it comes to their respiratory protection program. One of the most popular questions has to be the relationship between facial hair and its effect on respirator fit. You wear a respirator for a reason.

Question: Are hospitals requiring employees with beards to shave them off before fit-testing and using N95 respirators, or should employees with beards be excused from caring for tuberculosis patients? The question then becomes: Can employees with beards use the standard N95 respirators recently certified by the National Institute for Occupational Safety and Health NIOSH for protection of health care workers against tuberculosis infection? The answer is no, according to U.
All staff who, after a risk assessment has been completed, are required to wear a tight fitting face mask, must undertake a facefit test before commencing work. It has been shown that, because of better and more consistent fit results and ease of operator adjustment, re-usable respirators provide a more consistent and higher degree of protection than disposable paper mask respirators. For this reason, and taking into account that costly dedicated adapters are required for the testing of each manufacturer's respirators, it has been decided that wherever possible respirator type should be standardised across the University. This approach has been fully endorsed by the Procurement Department.
