It could even just be a volunteer service of community members with good upper-arm strength, first-aid training, and an extended form of Good Samaritan-law protections. Semi-professional first responders, with no other qualification than being a first responder.
So basically, lifeguards. For places other than pools.
Some communities that don't have many fires dispatch their firefighters for this, and that works pretty well. But most fire units don't have enough downtime for that to be workable.
