I was thinking of this thread when I read of a tragedy killing three people when a power line came down in their backyard. Victim #1 approached the line, tried to step over it - Zap. Victim #2 came to his aid - Zap. Victim #3 also came to render assistance - ZAP.

I cannot find the URL for the life of me or I would post it...

To get to your question, I might try to extinguish the fire first, although that could easily not work. Otherwise, choose a location where you can achieve maximum distance. I believe it is best if you can land on one foot. Wear rubber soled foot gear-it will help a little.
