Refreshed proposal - Emergency=disaster response

To the best of my knowledge, all SES units are equipped & trained to provide the same level of basic assistance (sandbags, tarps, ropes, chainsaws etc), while some units are e.g. also equipped with boats for flood rescue.

I wouldn’t try to discriminate between individual units based on what their specialisation, if any, may be.

This is one that I tried to cover with the landuse=emergency discussion. The area of the grounds is landuse=emergency, with a building=emergency, but inside that building is an emergency=disaster_response node for the SES unit, but also an amenity=fire_station node for the Rural Fire Service unit that shares the building.
