At 9:24 a.m., two employees were working on an electrical line in a concrete masonry unit. One employee was checking to see if the wiring was live or de-energized while the injured employee was peeling the electrical tape off the electrical caps with a set of pliers. While the injured employee was cutting the insulation, the pliers in his left hand contacted the live copper wire and the employee was shocked by 277 volts. The employee lost consciousness and was hospitalized.
