I used to have (until I moved) an 'Ambulance Card' by my phone with the Address, Postcode, National Grid Reference and the Page and Grid from the local county atlas. It also had instructions on how to find the flat - access was somewhat convoluted - worked out to be clear and concise. The point was, I live alone. So if I call an ambulance I'm likely to not to be a state to think clearly. That info was there so I didn't have to think. I had better make up another one for this address - although I have neighbours now who can do the call for me, if I can contact them. Actually, we have such bad access here that the Residents Association organises a visit by the Fire Brigade every few years to check and review the access plan. It involves breaking down fences but the route is a lot quicker than the 'obvious' one - and they can get the appliance to a position where the hoses will reach! Unfortunately this is the result of a fatal fire where the Fire Service _couldn't_ get rapid access and the hoses didn't reach. We had probably best work out an ambulance access plan as there are parts of the area where parking up in a non-obvious place and using a few yards of path not marked on the map would be a lot quicker than the several hundred yards to the normal access point.
