I've been in many situations from doing installs 30 years ago to sweeping now where I determined that it was too dangerous to do the job and let those in charge know it. That includes traffic, weather, darkness, shakey poles, dogs, bad neighborhoods and more. I tell them it's my decision, not their decision and if they have a problem with it to go out and do the job themselves.
