A friend of mine heads up a Community Emergency Response Team just outside of Washington, DC. Last time I talked to him, I asked him what they do for respirator mask fit testing.

As I think back to my years in emergency response, and my time working in a hospital emergency room, it doesn't surprise me too much. Back then, I wasn't even tested with a hood. It's probably because there were fewer regulations about fit testing. But knowing what I know now, it bothers me that our emergency response teams aren't better protected
