Carbon monoxide detectors will be mandatory in all educational institutes, announced Quebec Education Minister Jean-François Roberge Friday.
This comes four days after a gas leak at Des Découvreurs Elementary School in Montreal’s LaSalle borough that sent at least 35 children and eight adults to hospital.
“I am wholeheartedly with the families and the staff at Des Découvreurs Elementary. An event of this kind should never happen and I hope that this does not happen again,” he said.
“I am asking that all educational institutions acquire a carbon monoxide detector as soon as possible.”
Roberge said all schools and school boards will also be expected to conduct annual inspections to ensure the devices are working.
The minister said he will be asking the administrative body of all educational institutions to make sure their buildings have carbon monoxide detectors, as well as perform air quality checks and inspect the fuel-burning systems as soon as possible.

Montreal fire department chief of operations Francis Leduc explained there had been a malfunction in the school’s gas-powered heating system.
He said the gas was getting caught in the chimney and leaking back into the building.

Fire officials tell Global News the levels of carbon monoxide in the school’s heating room were at 900 ppm and 175 to 200 ppm in the hallways.
Provincial government norms allow for 35 ppm in a workplace environment and 10 ppm in homes for adults.
“Those are levels for a human adult. These are for people that are five foot seven, 170 pounds — adult people,” said Ian Ritchie of the Montreal fire department.
“The exposure levels or something they could withstand is much, much different.”
