Inquest: Inadequate Bracing Caused Accident
February 5th, 2010
A recent inquest into the death of 72-year-old builder Domenico Ranieri at a Saint John construction site in Saint John points to a number of safety lapses that contributed to the accident.
In October 2008, Ranieri, the owner of East Coast Rental Equipment Ltd, and a co-worker were securing 500-pound roof trusses for a warehouse storage shed being constructed when the trusses gave way after a brace was removed. Ranieri was killed and his co-worker injured after falling approximately 20 feet from the roof.
A WorkSafeNB investigation highlighted a number of concerns, including the fact that the gable was inadequately braced. According to the report, the lumber used for bracing was of insufficient size and length, and was inadequately nailed. Also, the spacing distance between the lines of lateral bracing at the truss top cord was beyond the normal limit. They also noted that neither worker was wearing any personal protective equipment or fall arrest systems.
The accident prompted several recommendations from the coroner’s jury, including a call for building inspectors and field engineers to “obtain basic knowledge of the Occupational Health and Safety Act (OHSA) to be able to identify potential violations.” They also recommended that WorkSafeNB’s building inspectors and field officers be given the right to restrict access to a work site which is apparently unoccupied if there is a perceived non-compliance to the building code or OHSA. This restriction applies until they are able to issue a stop work order. Apparently, a WorkSafeNB inspector had been on site earlier that morning, before the accident, but was unable to conduct an inspection because no one was there. Not long after he left, he received the call about the accident.
They also called for copies of building permits for non-residential projects to be sent to WorkSafeNB, so that they could establish a schedule of site visits to ensure compliance with the OHSA as construction progresses. Currently, WorkSafeNB is not notified of building permits issued by the City; instead that information is sent to Service New Brunswick. They also recommended that building permits also be displayed in plain view on every job site.
The presiding coroner also suggested that building designers be required to provide detailed truss erection instructions for all commercial buildings spanning more than 40 feet, seven inches, because the general instructions provided by truss manufacturers “have a little a caveat there that these instructions are good for installations up to 40 feet seven inches.” Any structure beyond that specified dimension requires the consultation of a professional engineer.

ESC technology is designed to help drivers maintain control of their vehicle when making sudden emergency maneuvers or turning on slippery corners, by automatically applying the brakes to certain wheels when a vehicle is skidding and possibly cutting power to the engine when necessary to help the driver maintain proper control. Data from Transport Canada data has shown that vehicles equipped with ESC are involved in fewer severe collisions caused by loss of control, resulting in significantly fewer deaths and injuries compared to those not equipped with ESC.
Did you know that repetitive strain injuries or musculoskeletal disorders (MSDs) account for as much as 40% of all lost-time claims in Canadian workplaces? Did you know that many of these injuries could be avoided simply by reducing stress in the workplace?
Earlier this month, the owner and operator of a Manitoba motor inn was found unconscious and rushed to a Winnipeg hospital, where he died 9 days later; a victim of carbon monoxide (CO) poisoning. Manitoba’s chief medical examiner said carbon monoxide, a tasteless, odourless, and colourless toxic gas, had leaked from a faulty furnace in the inn. As a result, Workplace Safety and Health shut down the furnace and will not turn it back on until it is repaired.

There’s been a lot of talk lately about Bill 168, The new law places new obligations on employers to address workplace violence and harassment, so it will be necessary to review and assess the risk of such violence, and update your company’s workplace violence and harassment policies to the new standards.
Labour leaders in Newfoundland and Labrador are calling for the creation of an independent committee of industry, workers, government and contractors to draft new occupational health and safety legislation for the province’s offshore oil industry. And they want that legislation enforced by the provincial government, rather than the Canada-Newfoundland and Labrador Offshore Petroleum Board (CNLOPB).
