Utility Fined $225,000 After Worker Killed, Others Injured While Working Near Power Lines

In March 2012, workers employed by a subcontractor were installing new hydro poles and wires under existing energized lines. Three workers were excavating a hole when the boom of a work vehicle came within three metres of a power line located about six metres above the hole. All three workers received electrical shocks, with one worker later succumbing to the injuries. The two other workers received medical attention at the hospital and did not suffer permanent physical injuries. A Ministry of Labour investigation followed the incident.

After a trial, Hydro Ottawa Ltd. was found guilty, as a constructor, of violating three sections of the Constructions Projects Regulation. These were failing to

• ensure the boom of a vehicle was not brought within three metres of an energized overhead conductor of 750 or more volts
• ensure a competent worker designated as a signaler was stationed so as to be in full view of an operator and had a clear view of the electrical conductor and of the vehicle, to warn the operator every time any part of the vehicle or other equipment may approach the minimum distance
• take every reasonable precaution to prevent hazards to workers from energized electrical equipment, installation and conductors

The company was fined $225,000 on March 29. In November 2013, a sub-contractor and co-defendant, Digsafe Inc. of Ottawa, had pleaded guilty in relation to the incident and was ordered to pay a fine of $125,000.
