BRIEF DESCRIPTION OF ACCIDENT
Two employees were spreading concrete as it was being delivered by 1 concrete pumper truck boom. The truck was parked across the street from the worksite. Overhead power lines ran perpendicular to the boom on the pumper truck.
One employee was moving the hose (elephant trunk) to pour the concrete when the boom of the pumper truck came in contact with the overhead rover line carrying 7,620 volts. Employee received a fatal electric shock and fell on the other employee who was assisting him. The second employee received massive electrical shock and burns.
* Safety training requirement was not being carried out at time of accident.
INSPECTION RESULTS
OSHA cited the employer for not instructing each employee to recognize and avoid unsafe conditions which apply to the work and work areas. Employer was also cited for operating equipment within ten feet of an energized electrical, ungrounded transmission lines rated 50 kV or less and not erecting insulating barriers.
