~6 years ago I got new countertops, and while they did the bulk of the cutting in their facility, they did do a few cuts in my front yard, creating a huge cloud of dust. The main parts of the counter arrived ready to assemble, but I think they cut a spanning piece for behind the stove, spanning the counters on either side.

My 8yo son came out to see what was going on, looked at the workers doing the cut without masks, and said "silicosis ain't no joke" and went back inside. I've taught him well.
