In North America Fire Depts are required to provide rest and nutriment to firefighters at given intervuls. This lessens the chance of illness and/or death from firefighting activities. Please see NFPA 1584 for details. We care about the safety and welfare of our emergency personnel. A far better service than the old tea pot in an equipment locker.

Not sure how it's done in the 'over the pond' but some UK brigades operate a firefighter welfare support vehicle that offers a refrigeration option to rapidly cool overheated firefighters. Merseyside is one such brigade that I can think of.
In addition to the cooling/warming(winter time) our units provide lavatory facilities. Some of your unit there also provide these features.I believe that in the archives of this site there is a photo of one such unit from the UK.

That's great info thanks chaps.
My local fire authority have a 4 hour rule which basically means a fire fighter is not expected to be working at a demanding incident for more than 4 hours. Welfare provisions consist of teapots in equipment lockers for most, occasionally public generosity and even more seldom a Salvation Army canteen van (God bless the volunteers for their service).
As for overheating, buckets of water are usually used.
My understanding is that is used to provide on-site emergency first-response treatment of firefighters (and I guess fire victims) suffering from dehydration, heat stroke, smoke inhalation and other problems not needing hospitalization or medical care. This jibes with some of the comments above
