I don't think it hurts to repost a safety thing like this. This, as the article says, is something that I think a lot of people take for granted, and we don't even think about it.
We actually had a call on an older gentleman not long ago who died due to a similar scenario. He was working in his garage with no ventilation, and wound up mixing some chemicals (woodworking, but same concept) and passed out, stopped breathing, and went into cardiac arrest.
The risk is there, so be smart about it.
