I sadly noticed that I am not only disabled but prone to falling. This is a tough one for me. So this is what I did:
I purchased a disposable inexpensive basic cellular phone PLUS a pair of reading glasses. The phone and glasses are covered loosely by a towel. The phone is charging all the time. Deciding where to put it led me to an outlet just outside the bathroom. The phone is ON THE FLOOR. Of course it's not guaranteed fool proof, but an auto LED night light seems to make reaching the cellular easier. I entered a list of speed dial numbers and taped 9-11 card in big letters next to the outlet. People who fall often suffer concusions and cannot remember their own name, never mind address.
AND plan ahead. Install whatever it takes to allow a person, a stepped grip bar "pull-up" device that allows her to pull herself first to her knees, then she can PUSH herself more upright. Is the bathroom floor slip-resistant? Have stainless grab bars to help with the potty and enter/exit the shower or tub.
I HATE THE IDEA OF NEEDING TO BE "EXPERIENCED" WITH THIS STUFF :(
