WATCH ABOVE: Some 2,600 workers headed back home Friday morning after the CNESST closed down the CHUM hospital’s construction site, citing poor air circulation, soaring temperatures and increased risk of heat exhaustion.

MONTREAL – Some 2,600 construction workers at the site of the future Centre Hospitalier de l’Université de Montréal (CHUM) in downtown Montreal are off the job Friday, following a decision Thursday night by Quebec’s Workers’ Safety Board (CNESST) to close the site down.

The reason behind the closure was lack of proper ventilation on the construction site, leading to soaring temperatures and an increased risk of heat exhaustion for workers.

Symptoms of heat exhaustion include include dizziness, loss of balance and even fainting.

The board said the work site will remain closed until its experts can confirm that conditions have improved sufficiently.

Fans that were previously installed to allow for better air circulation were no match for this week’s record-breaking temperatures and heat warnings.
