Abstract: Some employees were using a 1985 Pecco Putzmeistr concrete pumping truck (Model No. PMP 150P-8-M32/28, Serial No. 588) to pour concrete for footers at a single-family residence. The boom of the pumping truck was positioned over a 7620-volt overhead power line running alongside the street. One of the employees was handling the hose at the discharge end of the boom. The boom was within 0.6 meters of one of the phase conductors of the power line. Apparently, the wind blew the conductor into the boom and energized the truck. The employee handling the hose was electrocuted. The employees had received no safety training, and their employer had not contacted the electric utility owning the power line to deenergize or guard the line.
