A painter was electrocuted and his co-worker injured, when a portable aluminum extension ladder contacted a 7,200-volt powerline. This incident occurred as the two workers were painting a two-story aluminum-sided house. The powerline was located parallel to, and approximately 10 feet from, one side of the house. The powerline was 22 feet off the ground. The victim was using a 30-foot aluminum extension ladder to paint the upper part of the house, while his co-worker was using a stepladder to paint the window trim on the first floor. The victim had progressed to a point where repositioning the ladder was necessary to continue painting. He descended the ladder, placed the paint brush and bucket on the ground, and proceeded to move the ladder. The ladder tipped backwards and contacted the powerline. The current passed through the ladder and victim to ground while he was still in contact with the energized ladder. NIOSH investigators concluded that, in order to prevent future similar occurrences, employers and employees should: 1) use ladders made of non-conductive materials when working near energized powerlines; 2) contact the local electric utility company for assistance in de-energizing or sleeving powerlines if work is to be done near energized powerlines; 3) develop a safety program designed to recognize and avoid hazards (e.g., overhead electrical powerlines); 4) conduct initial jobsite survey to identify all hazards associated with the specific jobsite.
