Worker struck by a truck: CNESST identifies three causes

An incessant back-and-forth of trucks, a loud alarm that is difficult to identify and dangerous work methods considering the environment.

L has CNESST has made public the findings of its survey on labor accident killed Frederick Mailloux, shovel excavator operator at the enterprise service Normand Jeanson Excavation. The unfortunate event took place in South Stukely, August 15, 2017.
The survey retain three causes for the accident, reported Johanne Marquis, inspector, and Sebastien Thellend inspector.

The path taken by the worker crossed the trajectory of the dump truck during the retreat maneuver. He did not see the danger of the dump truck pulling back behind him, they say. The method of work used for the delivery of filling soil in the yard did not take into account the presence or possible movement of workers. A signalman should have been used to supervise the work, Marquis explained.
“The truck’s audible alarm was working, but the worker did not turn around to see it.”

“Research on this type of alarm shows that it is difficult to tell if the vehicle is moving forward or backward.”

On the day of the accident, expansion work on the Normand Jeanson Excavation parking lot had been underway since morning. The site required the delivery of fill soil by dump truck.
A truck driver started a recoil from Route 112 towards the yard looking in his mirrors, but he did not see Mr. Mailloux. The latter was walking on foot towards the end of the yard where the building was located. The worker, who was then backing the truck, was in his blind spot. The victim was crushed by the heavy weight, added Mr. Thellend,
The relief was called and the death of the worker was found on the spot.


Following the accident, the CNESST banned the continuation of the parking filling work. The resumption of work was authorized after the employer presented a safe work procedure, which included a traffic plan for the vehicles and the presence of a site marshal to direct the truckers.
The employer received a statement of offense which is accompanied by a fine ranging from $ 16,000 to $ 33,000, said Robert Larouche, Director of the Prevention and Inspection Department at the CNESST, without specifying the exact amount. This is the first offense on the Normand Jeanson Excavation file.
In the last five years, 21 deaths have been reported in this situation, Johanne Marquis said.
CNESST reminds that the circulation of self-propelled vehicles must be controlled so as to protect all the people on a building site. To this end, the prime contractor must plan the movement of these vehicles in such a way as to restrict backing up maneuvers and put in place safety measures to protect anyone traveling on the site.
The employer is required to take the necessary measures to protect the health and ensure the safety and physical integrity of its workers. It also has the obligation to ensure that the organization of work and the equipment, methods and techniques to perform it are safe. Workers must team up with the employer to identify hazards and put in place the necessary means to eliminate or control them.
CNESST will send the conclusions of its report to the organizations working in the construction field to inform them of the regulatory changes concerning retreat maneuvers of heavy equipment on construction sites, in effect since December 31, 2015.
