In my personal experience as an electrical engineer, I have used the technique of mitigating the risk multiple times when connecting electric transformers in multiple communities. The company I worked for, had specific workers whose job was to make sure the conducting wires in utility poles have enough tension and overall in charge of connecting the circuitry in the top of the utility pole. Although when the transformer is being connected there is no current going through, there is always a risk that something could go wrong and injure the person. A way used to mitigate the risk was by implementing equipment such as stairs with glass fibers and specialized security belts. There was no way to completely reduce the risk, but it was our responsibility to lower it as much as possible.
Let me know what you think.

Sincerely,
Roberto Pineda.
