Barrie company fined $200k for 2021 fatality
A Barrie-based millwrighting company has been fined $200,000 for its role in a 2021 workplace fatality.
Western Mechanical Electrical Millwright Services Ltd. of Brock Street in Barrie entered a guilty plea in provincial court to charges relating to a violation of the Occupational Health and Safety Act and its regulations. In addition to the fine, the company will pay a 25-percent victim fine surcharge.
On June 14, 2021,a worker was tasked disassembling a decommissioned primary heat transport pump motor at a facility where Western Mechanical Electrical Millwright was performing contracted work.
While attempting to remove a large flywheel from the motor’s hub, a supervisor connected hydraulic pressure to the hub.
Once the hydraulic pressure was applied, the supervisor began increasing the level of pressure to free the flywheel. This inadvertently caused the flywheel to move off the hub suddenly in an explosive fashion. The flywheel struck the worker causing a fatal injury.
An investigation by the Ministry of Labour, Immigration, Training and Skills Development found that the flywheel was attached to a rotating shaft. The flywheel measured 72 inches in diameter, was 6.5 inches thick and weighed approximately 7,200 pounds.
The investigation also revealed that the strong back bar and threaded rods, attached to the motor to remove the flywheel manually, were not installed in accordance with the flywheel removal instructions and could not be used to remove the flywheel.
The investigation found that there was no denoted hazard zone placed around the motor once the decision was made to use hydraulic pressure to remove the flywheel. There were no precautions or other safeguards, such as the use of a restraining device in place, to ensure that the movement of the flywheel did not endanger the safety of the worker and supervisor.
The investigation also found that while the supervisor had experience reviewing drawings similar to drawings provided by the facility where the work was being done, no one from the company had reviewed the motor disassembly job with the workers or reviewed the process of removing the flywheel safely from the motor.
Section 45(a) of Regulation 851, the Regulations for Industrial Establishments, requires that where materials, articles or things are required to be lifted, carried or moved, they must be lifted, carried or moved in such a way and with such precautions and safeguards, including protective clothing, guards or other precautions as will ensure that the lifting, carrying or moving of the materials, articles or things does not engender the safety of any worker.
Section 25(1)(c) of the Occupational Health and Safety Act, requires an employer to ensure that the measures and procedures prescribed by section 45(a) are carried out at a workplace.
As such, Western Mechanical Electrical Millwright was found to have failed to comply with section 45(a) by failing to ensure that a flywheel was lifted or moved in such a way and with precautions and safeguards to ensure that the lifting or moving of the flywheel did not endanger a worker.
