Please note, in the US under OSHA (the Occupational Safety and Health
Administration) regulations, any employee who is required to wear ANY type
of respirator, including a dust mask, MUST be fit tested prior to using this
equipment.

The OSHA code reference is: 29 CFR 1910.134

Dust masks ARE respirators and are defined in the code at 1910.134(b)

And if you wear a beard you can't wear a respirator--in fact your employer
can legally require you to shave if wearing a respirator is part of your
job.

Your employer is required, by US law, to provide you appropriate training
and fit testing before you use this equipment.

It's for your own good, don't use a respirator with out being fit tested, to
be certain you're being protected, and without having your health checked to
be certain that you can use the thing.

More information is avaliable from several sources but my favorite is
