Today, as I was walking through campus, I saw a cart full of wall debris. It must be some demolition going on in a building. I noticed one side of the pieces were of a different color. The pieces were like rocks yet the surface were smooth so it might not be paint. It could be tiles attached to rock.
My question is, would demolition of painted wall be done in a special way so that paint dust (with lead) does not spread? Or do people really just smash them and let dust float?
