I have an electrical engineering degree, paid attention in class, and got good grades. My thoughts are that every electrical problem has its own unique characteristics. Also, our lab experiments were a humbling experience. Electricity is many times unpredictable. You can fully understand the theory of electronics. Then, you step into the lab and realize that your theory is more like a general guideline of how electricity will behave.

In this situation, there are general guidelines to be safe. However, the consequence of being wrong is not receiving a "C" on a lab assignment. The consequence of being wrong is killing somebody. Accordingly, the best answer by far is to advise somebody to stay away and how to do stay away safely. The next best answer is to advise the person to get a job with the local electric company and learn the trade of dealing with downed power lines. I would NOT put my name on any other answers if you knew me in real life.
