could be my 19 year old son’s

He recently began working as a TV cable installer, and does not seem to be getting adequate pole safety training. It appears there are some shoe string operations in that industry, and that they are a bit lax on the safety training.
He is only on a pole maybe 5% of the time, (and we know that the cable lines are ‘usually’ the lowest ones..but then how long does it take to be wrong..and thus dead?

The question then is: what info is available on pole safety ...for cable TV installers? I spent a couple hours browsing the NIOSH website and found a few good items but did not see much on pole safety..mostly it just says..stay away. Not an option for him
