What should be in a home medical safety kit for a disabled person?

Varies a lot. Each type of disability has its own special needs. A caretaker will want to have spare equipment parts, extra medications, extra food and water, and a cell phone as well as a land-line phone to call for help. A land-line phone gives the 911 operator the caller's address, but a cell phone does not. Emergency battery back-up, emergency oxygen, or a gas-powered generator is recommended in some cases.
