I always hear the stories about things old timers slowly got injured by such as asbestos, silicosis from concrete dust, hearing impairment, ect. But i was running pvc the other day and wondered how that has effected people's health. I tried searching but didn't come up with too much other than it's toxic. There's many times I'm heating with a torch to form a bend and it burns it and u end up inhaling the black smoke or you're down in a ditch u dug and glueing pipe and the fumes from the can are straight in your face. I've always had headaches after and usually by the end of a day running pvc I'm about as high as a Georgia pine. Do you guys know any instances of recorded long term effects. What do u guys do for safety.
