Duct tape and electrical tape MAY be useful in such conditions, but I can't imagine anyone with any degree of sense depending on them if they didn't have to do so.

You hear about the successful (lucky) incidents, but you probably don't hear much about the unsuccessful ones, where they got a massive infection, gangrene, or their leg fell off, or something. Those people probably wouldn't be bragging that they used Duct Tape right up to the time the surgeon amputated some body part.

Contrary to what some people say, there still isn't any law against using common sense.
