Blog Post #1256 – Death of Worker, Injuries to Others Result in $175,000 Fine to Windsor Concrete Manufacturer

Excerpt from the government of Ontario’s ‘Newsroom’

One worker was killed and another seriously injured when anchor plates being used in the construction of a bridge girder slid from their supports and failed, striking the workers. The employer was Pre-stressed Systems Inc. (PSI Inc.), of Windsor, Ontario, a manufacturer of pre-stressed and pre-cast concrete products.

On April 12, 2018, workers were working on the concrete form for a large pre-stressed bridge girder that PSI had been hired to manufacture for the Nagagami River Bridge project. The process of pre-stressing concrete is a means of increasing the strength of a concrete structure, using tensioned steel cable strands embedded inside the concrete.

Strands of cable are passed through a concrete form and secured to anchor plates and anchor grips. After the concrete cures around the stressed cables, the exposed ends of the cables are relaxed (de-tensioned) and released (cut).

To take the tension off the cables, hydraulically powered cylinders are used, and support sleeves are manually removed by workers. During this process, the cable strands act like big elastic bands; when the cable strands are stretched and held, they hold a large amount of stored energy, and proper de-tensioning equipment and procedures are needed to safely remove the tension from the cable strands.

Four workers were removing the support sleeves from the cylinders when anchor plates – to which the still-stressed cable strands were attached – suddenly failed and struck two of the workers. One of the workers died, another sustained multiple injuries and two others survived without significant physical injury.

The Ministry of Labour’s investigation determined that one of the key contributing factors to the incident was the company’s failure to use a wire guide on the de-tensioning end of the cable strands as required by the manufacturer of the de-tensioning equipment. Because no wire guide was in place, the anchor plates slid from their supports and catastrophically failed.

Failure to use the required wire guide constitutes a contravention of section 25(2)(h) of the Occupational Health and Safety Act.

Following a guilty plea on January 20, 2020, PSI Inc. was fined $175,000 in provincial offences court in Windsor by Justice of the Peace Susan Hoffman; Crown Counsel Steven Succi.

The court also imposed a 25-per-cent victim fine surcharge as required by the Provincial Offences Act. The surcharge is credited to a special provincial government fund to assist victims of crime.

My opinion

The law(s) in contravention:

PSI Inc. was found guilty of a contravention of the Ontario Occupational health and Safety Act (OHSA) section 25, subsection 2(h) which states,

“The employer,

Shall do everything reasonable in the circumstances for the protection of a worker.”

It seems very cut and clear. The workers were in danger because the employer did not see fit to ensure wire guides were being use. It must have been a regular occurrence since there were no complaints for unsafe work by the workers.

I bet they have to use them now!

Section 25, subsection 2(h) has been used more than any other section of the OHSA. In this case, it did seem appropriate.
