I remember my first exposure (no pun intended) to respiratory protection as if it was yesterday. As a fresh-out-of-college insurance loss control representative, I believed that industrial hygiene was not just for the professionals, so I embarked on an IH adventure.
My adventure took me to wonderful places: PEL Place, Toxicity Trail, Dichlorodifluoromethane Avenue, and the like. Why people should be using respiratory protection became clearer, so I asked how it was used, who was using it, and why.
