CBC NB - WorkSafeNB says three charges have been laid against Irving companies in connection with the explosion that happened almost exactly one year ago at the Irving Oil refinery in Saint John.

One charge under the Occupational Health and Safety Act was laid against Irving Oil Limited and two charges were laid against the employer, Irving Oil Refining GP on Oct. 1.

WorkSafeNB says it will not release its final investigation report on the incident nor comment on its findings, as a result of these charges being laid.

The refinery explosion shook east Saint John on Canadian Thanksgiving weekend last year.

Almost 3,000 people were working on site as a massive maintenance project was underway.

It took weeks for WorkSafeNB investigators to gain access to some parts of the refinery that had burned for days.

According to WorkSafeNB, Irving Oil is charged under subsection 11(b) of the act under duties of owner: Every owner of a place of employment or part thereof shall take every reasonable precaution to ensure the health and safety of any person having access to or using that place of employment or part thereof.

Irving Oil Refining GP is charged under subsections 9 (1)(a) of the act: Every employer shall take every reasonable precaution to ensure the health and safety of his employees.

Irving Oil Refining GP is also charged under subsection 68(b) as it relates to piping and apparatus for hazardous substances.

An employer shall ensure that piping and apparatus for a hazardous substance is maintained in safe operating condition and regularly inspected, it states.
