I would say using a chainsaw up on a ladder ranks pretty high for me.

 

I spent a couple of years working in a sawmill right out of school. Most dangerous tool I've worked with was also a chainsaw. I was using it 80 feet off the ground on a log ramp consisting of a grid of 10" square steel beams every 8-10 feet. On a 30 degree slope. Constantly sprayed down with sprinklers. To cut out stuck logs that would then break in unpredictable ways.



It was a sh*t job, I only did that part for a couple weeks filling in for the normal guy because he fell the 80 feet to the ground.
