I'm in the same boat as Brangdon 2 broke arms because I have one on each side also. Wave oneside PSK II on the other.
The hardest would be in winter gear but I should be able to unzip and cross draw is one arm works.
With 2 broke legs I could get the belt cut but don't know if I could then get out.
A noise maker especially a whistle is a very good idea.
