Workers injured in a fire five years ago at the Co-Op Refinery in Regina say they continue to suffer from the incident.

"I am constantly in fear of losing my life," Vasiharathas Subramaniyam, one of 52 workers hurt in the Oct. 6, 2011 fire and explosion, told a provincial court judge Tuesday during the sentencing phase related to the legal proceedings following the fire. "My life was put at risk [and] I still suffer from this incident."

The judge imposed a fine of $280,000 against Consumers' Co-operative Refineries Ltd, owner of the facility which is located on Regina's northeast end. The company had previously pleaded guilty to a contravention of the Occupation Health and Safety Act, admitting it failed to ensure all work was sufficiently and competently supervised.

During sentencing submissions, a number of victim impact statements were read in court from workers who said the Co-Op failed to visit them, follow up, or apologize over the incident.

"The truth is they have done nothing and that disgusts me," said Shawn Farrell, in a statement that was read into the record. "[I'm] astounded at the lack of human compassion."

Co-Op did submit a formal apology to the court Tuesday. The company's lawyer said a pipe linked to the explosion was installed in 1961 and was the wrong thickness. The lawyer said if it had been the correct thickness, it would have lasted until its scheduled replacement which was due in 2011-2012.

The fine, $200,000 for the infraction and $80,000 as a victim surcharge, was suggested by the lawyers and accepted by the judge. The company was given two months to pay.

Farrell told the court that he believes the fire was not an accident.

"These companies believe they are above the law," he said in his statement. "This company didn't have any concern for our safety".

Another worker also expressed dismay with the company.

"The Co-Op refinery failed us," Irene Rombaut said in her statement, which was read into the record by the Crown prosecutor. It was noted that she now suffers from depression and anxiety.

A total of five occupational health and safety charges were laid against the company on July 31, 2013. Four of the charges were withdrawn by the Crown.
