I was about to post this, just finished watching it online.
It's ultimately up to the technician to follow safety procedures but if he stands up to his/her foreman and say something isn't safe they will probably just get rid of him and replace him with someone who will do it.
OSHA seems to only go after larger companies with deep pockets they can levy large fines on. The carriers distance themselves from the sub contractors they hire so they cannot be held responsible for safety violations.
I work for a major north east utility and safety is paramount. Technicians are suspended if caught not following safety procedures. OSHA is always inspecting our job sites to make sure we are following safety procedures.
