And many other places, yes… that’s why I was surprised to see that 
emergency=stop_button has only been used a single time worldwide and there 
don’t seem to be any other similar values in the emergency key.

Stop buttons are also found on escalators.

On a remotely related note, while looking through taginfo, I was surprised that 
emergency=stop_button has only 2 uses and there don’t seem to be any other 
values to tag something of that nature.

 

On Wikipedia it’s documented at https://en.wikipedia.org/wiki/Kill_switch

 

A tag for this would certainly be useful e.g. for petrol stations to mark the 
location of the emergency stop button for the pumps…

 

Stop buttons are also used in workshops - to stop rotating machinery without 
getting near it, can save a life. 

 

Yes, that was my point.  Emergency stop buttons aka kill switches (Not-Aus in 
German) are something that should be of general interest to map, and the ones 
for the pumps at a petrol station is just one possible example.

In addition to just tagging the position of the emergency=stop_button, some 
scheme to define what exactly is affected by it might be useful.

e.g. something like a type=effect relation, with effect=stop (or 
emergency_stop) and the emergency=stop_button node (role = effecter or maybe 
source) and man_made=fuel_pump nodes (role = empty or maybe target).

That general scheme could be applied to pretty much everything. If someone 
wants to go wild with indoor mapping and map light fixtures and switches, no 
problem. Call buttons for elevators, door bells, whatever.
