Pardon my ignorance, but why does an EMS pilot have to don an N95 mask?
N95's don't seal anyways, do they?
Communicable diseases, OSHA, I would guess? In 13 years, I've masked up a half a dozen times, once when the ambulance medics had their paper jammies on as well as gloves and masks. Even the volunteer firefighters gloved and masked up to help load.
All I know is that 'universal precautions' are an annually recurring subject and I have to be recertified every year with an N95. If they'll pay me time and mileage to do so, it's important to somebody who knows something.
N95 masks are also good for fogging up your glasses when you exhale. The program bought some with flapper exhaust valves 3 or 4 years ago to minimize that. I haven't had to mask up since....
The GoM guys should think about respirators, too- hydrogen sulfide is nasty stuff.
