If mobile equipment contacts an energized overhead power line, what should the operator do?

• A. Exit the machine immediately
• B. Stay in the machine, and if safe, move it
• C. Try to flag down help
• D. Disconnect the power line

Answer: (B)

Staying in the machine is the safest course of action if mobile equipment contacts an energized overhead power line. When a machine is energized, it forms an electrical path that can be highly dangerous. Exiting the machine while it is still in contact with an energized line could result in electrocution, as the operator could become a pathway for electricity, especially if the ground is energized. By remaining inside the equipment, the operator can avoid bridging the current path to the ground. If it is safe to do so (i.e., the equipment is not thrashing or in imminent danger of further contact), the operator can carefully maneuver the machine away from the power line without discharging any current that might travel through the path of least resistance. This procedure is vital for protecting the operator's life and adhering to safety practices concerning electrical hazards. Other actions, like attempting to exit the machine, flagging down help, or disconnecting the power line, could put the operator in harm's way by exposing them to the electrical hazard or further complicating the situation.
