I have searched on this topic in the past and there is very little out there.

The only decent, profressionally done document I have ever run across is produced by the County of Los Angeles's Emergency Survival Program in conjunction with the American Red Cross. The ESP's website is www.espfocus.org. From here, you can drill down to various resources, including this webpage of lots of publications produced by ESP, many in Spanish. In particular, you might be interested in this booklet called "Emergency Preparedness: Taking Responsibility for Your Safety. Tips for People with Disabilities and Activity Limitations". A lot of it is general preparedness advice, and it does have a bunch of questions to get you to think about potential problem areas specifically for this population that you may not have thought of like "Can you give quick instructions about how to safely carry you if needed?" The information may seem obvious to you in your head, but if you have never actually tried or practiced explaining the info quickly and succintly to someone else, in a real emergency, you could fumble with your words, give conflicting info, etc. Anyway, I think it's a worthwhile resource for everyone to read through since we will all interact with people with mobility issues at some point.

Oh, here's the really sad thing about this valuable document. I remember hearing on the radio last year when this booklet was first produced that the county didn't budget enough money to actually reproduce and distribute the handbooks! As far as I know, unless more money was coughed up after that story came out, the Internet is the only widely accessible way to get this document. <shakes head>
