The infographic, created three years before the coronavirus outbreak, has offered some comic relief.
Coinciding with the Centers for Disease Control warning Americans to prepare for the spread of the coronavirus — with “the expectation that this could be bad” — a 2017 infographic with facial hair guidelines for those who wear respirators at work is getting noticed on social media.
The infographic suggests facial-hair options that won’t interfere with respirator effectiveness — with styles including the soul patch, side whiskers, pencil and lampshade as being approved, although a clean-shaven face is ideal. Meanwhile, sporting stubble, an extended goatee, chin curtain, mutton chops, and full beard are all risky choices
“Therefore, the vast majority of particles, gases, and vapors follow the air stream right through the facial hair and into respiratory tract of the wearer,” it continues. “In fact, some studies have shown that even a day or two of stubble can begin to reduce protection. Research tells us that the presence of facial hair under the sealing surface causes 20 to 1000 times more leakage compared to clean-shaven individuals.
However, respirators, such as the N95, are typically worn by healthcare workers, including infectious disease physicians, nurses, or respiratory therapists. They filter air and protect outside germs from coming inside the mask.
