Yes, that's something else we need to be aware of! I had the fire service come in on Saturday to give our house a free fire check, set up by our care company. I agreed, as I thought the Health and Safety police were at work, or it was bound to cost me money. Anyway, a very nice guy came out, it was just to register S as wheelchair bound therefore, would need extra help, in case of a fire. They log it on to their computer and if there is a problem at our address now, they know it has to be a very quick response with the right equipment for S.
I wouldn't have a clue where to start, if the care company hadn't suggested it. It's not as if they are in the phone book, well I don't think so, but they might be. I would certainly ask your care company or the DN, if they come. Or social services.
Lots of love
