The Mine Safety and Health Administration (MSHA) issued a Close Call Alert after a gravel truck came into contact with an overhead wire. A tractor trailer was dumping a load of gravel at a surface sand mine when it came into contact with the overhead wire. The overhead wire then pulled and snapped a ground wire on an adjacent power pole, causing the energized 13,800-volt wires to arc and trip the power.

The incident occurred because 10 feet of clearance was not maintained between the equipment and the power lines. Luckily, no one was injured during the incident, but electrocution was a possibility.
