I bought a house-built in 1940- and recently removed and replaced the shutters myself.

Question

I just found out that my house has asbestos siding, which is not harmful if it is left alone. However, I used a power drill and 3inch screws to reattach my shutters. Could this be harmful to me?

Answer 1

could it be yes was it probably not you were outside  little breeze blowing the asbestos just drifted in the air if there is a next time just make sure you put water on the siding before you drill

Answer 2

Only if you inhaled the dust, which is very very fine.  In the future, use a good mask.
