Well, I’ve often seen their location marked on emergency plans. I agree that they aren’t something that should normally be rendered at most of the usual zoom levels used for OSM, but once you get into detailed indoor mapping, I think they are something that’s worthwhile mapping.

The thing about emergency stop buttons is that they tend to be highly visible, in obvious locations, and there are often big signs. You shouldn't need a map to help you find one because they're for rapid use in an emergency. Maybe for petrol stations it's a good idea, if there's only one such button for all the pumps. But even then you're not going to look at a map to find it, you'll look for the sign. So I'm not surprised they haven't been mapped very often. -- Paul
