Hi everyone, this is my first post, so if this post in the wrong section, please forgive me.
My question is in regards to protective equipment to be used on-the-job. I recently got hired to run performance tests on fiberglass insulation. The labs have sheets of exposed fiberglass everywhere, but there are filtration systems in place to keep airborne fiber dust beneath permissible exposure limits - negating the "need" for a respirator (there is a second room where blow-in insulation is tested, and here a N95 respirator is required).
Despite being under the PEL, following a 2 hour on-site interview I had an itchy throat (might be coincidental?). I'm wondering if you guys think I should wear a respirator even while I'm in the room under the PEL. None of the employees seemed to be affected, and I don't know if I'm just reacting to psychsomatic symptoms. Basically I'm curious to see what most people here would do if they worked in a room with fiberglass sheets for 8 hours a day.
