A worker for an excavation company and two workers employed by a subcontractor were installing new hydro poles and wires under existing energized lines. The workers were excavating a hole when the boom of the vehicle came within three metres of the power lines, which were about 20 feet above the hole. All three workers received electrical shocks, with the excavation company worker dying from his injuries. The excavation company pleaded guilty to failing to ensure that the vehicle’s boom wasn’t brought within three metres of the energized power line and was fined $125,000 [Digsafe Inc., Govt.
