You could use a diving bell Jeff or just SHAVE like the rest of us civilized men do.
Just pullin' yor jeeber Jeff, I know where your comming from, I used to keep a beard every winter years ago and had the same problems with the dust maskes. the beard made them pretty much usless.
Of course with the blasting you should be using a diving bell or rather a hood with fresh air coming in. That taint very practicle for the otheres though. Even the full face masks for spraying won't cover a full beard.
Now if you are willing to get rid of the full beard and just keep one of those Devil beards like Bruce Springstine and other celebs have that would solve your problem also.
