That takes me back to a club I was in during the '80s. The instructor had a space heater that looked a lot like this. Basically a horizontal tube with an open flame that she used to heat her garage. She did an safety demonstration by dropping a paper towel into the flame, so we 6-year-olds would know what happens when you go near the heater. You burn, children. You burn. Effective.
When I was a kid, a neighbor was shot in his garage. There were definitely two stories that went around the neighborhood. One said suicide and the other said “cleaning his gun.” One of those was repeated when kids were around. The other when they thought no one was listening.
Years back, I read was a very odd story about the Korean belief that falling asleep in a closed room with a running fan would result in death. This also seems to be a cover story for suicide.
