Is your facial hair fit for fit testing?

To beard or not to beard. That is the question.

 

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.

 

For the respirator to provide the assigned protection factor, the respirator must form a tight seal to the user’s face which can be comprised by having facial hair.

 

Unfortunately, guys, this means that wonderful beard you’ve been cultivating may have to go if wearing a properly fitting mask is a requirement at your workplace.

 

However, there’s still hope – keep reading for our guide on what facial hair you can keep when being fit tested, or ask us a question using the contact form provided.

Particles under 10 microns in diameter are defined as respirable, meaning that these can penetrate the unciliated airways of the lungs, potentially resulting in chronic respiratory health issues. Human hair is on average 50-70 microns, and therefore much larger than these particles.

Fit Testing standards do not permit facial hair that interferes with the sealing surface of the respirator or interferes with the valve function of the respirator; for the respirator to provide the assigned protection factor, the respirator must form a tight seal to the user’s face.

So, unless you are rocking a moustache, it’s time to break out the razor.
