I was grinding in the pole barn last year, and watched a spark fly right onto a scrap of steel wool that survived sweeping, and it started up. I stomped it right out--it would have consumed the scrap and smoldered out on the concrete. If it was more cluttered, or I had jumped to metalwork right after wood work without sweeping the area, I'd have had a lot more combustibles, and a lot more difficulty tracking the sparks. Got me worrying about all the little sparks I never see land, and paying a lot closer attention to my work area and the spark zones for metal work. If I have to launch a whole lot of sparks airborne I'll take it outside.
I've started little smudges grinding, welding and sweating pipes, but they have all been right at or near the work, and been put out with a swat. Sparks can fly well out of the "range of attention".
I don't think a person ought to spend a life worrying about all the things that can possibly go wrong, but paying attention to, and using the best fire and electrical safety practices you know, for the areas you frequent and invest in, is time well spent.
Also--steel wool is an INCREDIBLE accelerant/fire starter--not a good thing to have laying about wherever sparks are present... everyone probably knows that one.
