4. What do you do with employees who have the facial hair? (What if the beard or moustache is small enough that it is contained inside the respirators ?)

Tight-fitting respirators require the wearer’s face to be clean shaven where the respirator’s seal comes in contact with the skin. If the facial hair does not extend far enough to interfere with the device’s seal in any way, or interfere with the function of the exhalation valve, the wearer may wear it with the approval of the respiratory protection administrator.
