Personally, I think it depends on what kind of technicians you are, equipment, that is, equipment safety performance, inspection and maintenance. If it is electrical equipment, it is mainly the reliability of line equipment and wires, grounding and other links. If it is a craft class, the suggestion is to operate the program and increase training. The biggest hazards in coal mines are dust related to explosion and mine collapse. Knowing the key points and how to protect, avoid and reduce related hidden dangers is almost the same. After all, you are just a technician. I'm afraid you don't know much about this. You can ask your safety director and full-time security officer, they will provide you with better direction and focus.
