Quebec’s workplace health and safety board says design failures led to a scaffold collapse that killed two workers and injured several others at a western Quebec paper mill in October 2021.
The Commission des normes, de l'équité, de la santé et de la sécurité du travail says in a report released today that an engineer working for Boileau & Associés—the company that designed the 16-storey scaffold—improperly calculated how much weight the platform could hold.
The safety board says the engineer—who is not named in the report—underestimated the load capacity of the scaffold by more than 25 percent, a difference of more than 4,000 kilograms.
It says the seventh floor on which the collapse occurred was not properly braced and unable in certain places to support the weight of the workers.
Plant owner Domtar says the two workers who died were Yan Baillargeon, 39, and Hugo Paré, 22.
They worked for contracting firms that were doing maintenance on the plant in Windsor, Que.
