I work in an oil refinery and we have to be ready to don SCBA's at any time. My vocation lies within the Fire/Rescue sector (mostly prevention) and I also have to set the example by staying on top of it. No matter how much I like to have at least a VERY short beard.Interesting. I'm curious: May I ask politely what general line of work that might be? My understanding was that most professions permitted facial hair -- at least a mustache, if not a beard. The one exception I can think of would be the military (with the possible exception of the Navy).
