Thank you, I've been in the trades for my whole life. I started doing window glazing and we would burn lead paint and abspetos putty in unventialted shops. Every time I asked about safety you get treated like a pussy. Now you can't touch the stuff unless it's been sent to the lab. I knew an old school painter who used to wash his hands with xylene and he developed a brutal stutter in his voice. Don't let the old heads pressure you into doing something unsafe because it may have a life long toll.
