A masonry contractor was killed and another received a massive electrical shock and burn while spreading concrete behind a concrete pumper boom truck. One employee was moving the hose to direct the flow of concrete when the boom of the pumper truck came in contact with the overhead line carrying 7,620 volts. The employee received a fatal electric shock. The second worker received a massive shock and burns when the first employee fell on him.
The employer was cited by OSHA for not educating the employees on recognizing and avoiding unsafe conditions and for operating the equipment within 10 feet of an energized electrical, ungrounded transmission line rated 50 kV or less and for not erecting insulating barriers.
