1 in 250,000 or less. the main concern with asbestos is for people who worked with it every day. Occasional exposure should be avoided but don’t lose sleep over one project now that it’s over

In 1980 I repaired the hinges on a fire door at my high school. I cut into the door and put asbestos dust all over everything when I got into the core of the door. I was gaging and choking like crazy for 10 minutes but my lungs are still working fine. I’ve had chest xrays and a heart stress test since and nobody has said anything though I have not told my doctor about the exposure. (Um, hope he doesn’t read this!)

I have been a carpenter for 30 years and have removed all sorts of stuff the EPA has banned.My lungs are still in perfect shape.Next time and every time you do removal you should where a dust mask.

slim to none for such a small exposure, and slim just left the building. i know old-timers that used the stuff for blankets and worked with it on a daily basis for many years… they are still ok…. and they get a mandatory chest x-ray every year…. don’t worry
