Missing Emergency_Power_Off tag

I think we miss tag to indicate Emergency Power Off and Emergency Gas Off of the object or area.
This is very important when it is necessary to immediately cut off the media.
I propose adding a tag for the node and the area - “emergency=power_off” and “emergency=gas_off” ".

You should discuss new tags on the tagging@openstreetmap.org mailing list. ‘power’ tags have been long discussed there.
