The use of aluminium ladders around high voltage power lines has resulted in a significant number of electrical injuries and electrocutions. Workers often misjudge wire distances or lose control of fully extended ladders, thereby exposing themselves to electrocution hazard. High-voltage electrical burns of two workers using an aluminium ladder that contacted a high voltage power line are reported. The circumstances surrounding the injury, the clinical management of the case, and the methods of prevention are presented and discussed.
