Three companies were convicted on October 27, 2017 for violations related to an arc flash after a worker was injured at the South West Detention Centre (SWDC), 4819 8th Concession Road, Windsor, Ont.On May 28, 2013,  a worker was cleaning a circuit breaker compartment with a conductive tool. The worker made contact with live electricity and was injured in an arc flash that produced a large ball of fire. Another worker used a fire extinguisher to put out the flames. The injured worker required hospitalization.

Three contracting companies were named as defendants in the case for violations of Ontario Regulation 213/91, the Construction Projects Regulation, contrary to the Occupational Health and Safety Act, Section 23(1)(a), as it applies to electrical hazards in construction projects.

  • Toromont Industries Ltd., 3131 Highway 7 West, Concord, Ontario, contracted with J.M.R. Electric for a portion of the electrical work and the employer of the injured worker.

All three companies were convicted under section 190(4) of the regulation, which states that “the power supply to the electrical equipment, installation or conductor shall be disconnected, locked out of service and tagged… before the work begins, and kept disconnected, locked out of service and tagged while the work continues.”


All three companies were convicted under section 184(1) of the regulation, which states that “no person, other than a person authorized to do so by the supervisor in charge of the project, shall enter or be permitted to enter a room or other enclosure containing exposed energized electrical parts.”

Toromont was convicted under section 187 of the regulation, which states that “tools, ladders, scaffolding and other equipment or materials capable of conducting electricity shall not be stored or used so close to energized electrical equipment, installations or conductors that they can make electrical contact.”
