Not sure if a safety program would have prevented this or not but a big part of the burden is with the man lift rental companies. Over time, the lifts get paint on them and the safety stickers (the kind with the pictures of staying away from power lines, transformers, etc....) get covered up and not replaced.
Also, the rental companies need to remind everyone about the power lines and make sure that if the people renting the lift don't speak english then the safety warnings need to be in other languages like french, spanish, chinese, german, etc.... so that the safety messages can be understood.
Maybe a good idea instead of the safety stickers, maybe like luggage tags to where when they get damaged or covered with paint, just cut them off and replace with another as the stickers from the factory get covered up with paint, the new stickers probably will not stick to the dirty/oily painted surfaces.
It is a shame that every year people get burned and/or electrocuted from power lines, we really need more safety messages sent out, more safety training and maybe even start showing pictures of the people that have been electrocuted (very gross to see) so that people have a visual understanding of what high-voltage power lines can do to a body, how fast you can die and what happens to your body (won't go into very gross details here) so people will take the power lines more seriously.
Growing up in a tree trimming business we were always told to stay away from all wires on the telephone pole and the tree branches that were close to the lines were left up to the more experienced guys or my dad to make sure that people were always safe and make it home to their families every day.
We had the insulated hot-sticks, safety ropes, etc.... to deal with getting close to the wires but we never touched the wires no matter what and the tree branches that were close to the wires were carefully cut so they would not land on the wires or touch the wires, safety for our guys was always more important than making a few bucks.
