Heatstroke, even in May, contributed to the death of a construction worker, concludes the CNESST in a report that has just been released.
The man, who worked as a roofer, died on May 14 in Boucherville. He was working on repairing the roof of a house.
That day, the temperature reached 27 degrees. With the Humidex factor, the perceived temperature was 30 degrees at the time of the accident, according to the Commission des normes, de l’équité, de la santé et de la sécurité du travail (CNESST).
The worker had felt unwell, weak, and confused. He sat down on the roof. After a few minutes, he stood up, but lost his balance and fell from the roof, a height of 5.15 meters.
As another cause of death, the CNESST also noted a lack of planning and control of fall protection measures. The worker was wearing a harness, but it was not anchored to a fall arrest lanyard.
The Commission emphasizes that the height of the house, coupled with the degree of roof slope, meant that a fall protection system was required.
