Three Workers Burned in Arc Flash at Ontario Mall

workers burnedLondon, Ontario – O’Connor Electric Ltd was fined $60,000 this week as a consequence of a Jan 2018 arc flash incident which burned three electrical workers at an Ontario shopping mall. The company plead guilty to failing to establish and implement written measures and procedures to ensure that its workers were adequately protected from electrical shock and burn.

At the time of the arc flash incident, a crew of six were upgrading the service in an electrical room at the mall. The workers were planning on installing a new disconnect switch and wiring. Three O’Connor Electric employees has started installing the disconnect when an arc flash occurred. Canadian Occupational Health and Safety officials determined that the existing service had not been shut down when work began. Mistakenly working on an energized electrical system lead to the arc flash which burned the employees.

In Canadian court proceedings this week, O’Connor Electric Ltd. and one supervisor plead guilty. The supervisor was charged with failing to ensure workers followed OHSA guidelines for properly disconnecting the power supply. The company was charged $55,000 in penalties, and the supervisor was fined $5,000.

Ontario Construction Regulations dictate that 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.” Accordingly, the Ministry of Labour found that O’Connor Electric failed to establish working conditions compliant with that regulation, and that the supervisor failed to ensure that workers followed the regulations.

Arc flashes are violent and lightning-quick. They can cause electrical equipment to explode, resulting in injury or death to workers and destruction of electrical equipment. There are many avenues to mitigate or reduce the risk of arc flash incidents and their threat to electrical and maintenance workers.

Four Workers Injured in Explosion at Saia Motor Freight Line

St. Louis, MO – A flash fire caused by a propane forklift accident sent four Saia Freight employees to the hospital in August 2014 and has resulted in numerous OSHA fines for the company.

Two forklift operators were changing a propane tank on a liquefied petroleum gas-powered forklift inside a freight trailer when a loose coupling connection allowed liquid propane to leak, vaporize, and ignite.

The resulting flash fire caused burns – A lead forklift operator and a newly hired worker suffered critical burns, another worker sustained burns to his legs while he helped extinguish his coworkers’ clothing, and a fourth worker using a forklift nearby also received burns.

As a result, OSHA has cited Saia Motor with one willful and 11 serious safety and health violations and proposed penalties of $119,000. OSHA issued a willful violation for Saia’s use of several powered industrial trucks with defective or bypassed safety switches.

“Workers must be trained to avoid deadly combinations of flammable fuels, ignition sources and confined spaces, which allow vapors to ignite quickly,” said Bill McDonald, OSHA’s area director in St. Louis. “This incident should remind all employers that using forklifts is one of the hazards workers may face daily.”

OSHA issued serious violations for: not evacuating the work area after flammable gas was released; not requiring forklift propane containers be switched in an adequately ventilated area; mounting gas containers on the cylinder indexing pin correctly; training workers on extremely flammable gas hazards; requiring hand and eye protection when changing cylinders; labeling hazardous chemicals in the maintenance; and training powered industrial truck operators. Several electrical safety hazards also were found.
