Hey, what do you think he’ll be doing the other three weekends a month? 
Yes I am sure, and if it wasnt’ after hours, I’d call Albany, get the Department of Health, talk to the NYS EMS Co-Ordinator and quote chapter and verse of the law. You may not ride on a NYS Certified Ambulance unless you can have a tight fitting seal on a H.E.P.A. Mask.
You are not going to like the answer as to why your statement is correct- that Hatzolah Service amongst other EMS services run by Orthodox Jewish communities do not have to shave off their beards. It’s not something I can quote chapter and verse because it is off the books, and therefore has no place on the Straight Dope.
Email me, Chaim.
