I have a couple. First when I was building my house I had an idea for the wood siding but couldn’t afford to have it custom cut. So I did it myself. Spent a good part of the winter in the basement of an unheated house milling 10” cedar boards on a router table. Lots of sawdust. Someone had given me an old pot belly stove so I figured the easiest way to get rid of truckloads of sawdust was burn it. Works fine as long as you let it burn down before opening the door again. Yep blew the door right off that stove and put me on my butt A little further along in the construction I come home from work and open the front door. House Is filled with smoke. See the wife and step father on their knees trying to light the large fireplace. Both in rapt attention to the smoldering flame but oblivious to the smoke pouring out above their heads. Gently reminded them they needed to open the damper
