Changing the Beard Rule
#92
Well in the non-aviation world, there is a known legit concern with beards and high-concentration O2...beards will essentially explode if exposed to an ignition source in an O2 environment. You can easily try it yourself if you need proof (legal disclaimer: don't try this at home).

Many years ago I hosted a new hire pilot at my place. A large class had been hired, and there was a room shortage, so many of us offered up some space to accomodate the new hires. This particular individual was from another country, and he had a beard. During the ground school, he was privately counseled to lose the beard.
We had a discussion about it that evening. He was very upset. He needed the job, needed the experience, but he'd always had the beard, and said it was a part of who he was. I told him he would need to decide which had a higher priority in his life; working for a certificate holder in advancement of his life-long career, or looks and whiskers.
He quit.
He was an idiot.

Even then they do not explode.

Almost anything can burn in 100% O2. If it's even a little bit flammable in air, it will burn with extreme vigor in pure O2. A beard would probably not quite technically explode, but you sure as hell wouldn't want it attached to your face if a spark landed on it..
Google steel wool + O2 if you need the visual.

Not talking about spontaneous combustion, but rather an ignition source.

Oxygen concentration can enhance combustion. Hair burns, and applying oxygen to a flammable item while burning is taking place will accelerate the combustion process.
Unless you're stupid enough to smoke inside an oxygen mask, this generally isn't a problem. Simply applying oxygen to a beard will not cause it to burn. How many circumstances can you think of in which an ignition source is applied to a beard in a cockpit while wearing an oxygen mask?
Are you aware of an ignition source inside an oxygen mask?
