School board to inspect all schools after carbon monoxide leak

The head of Montreal'sMarguerite-Bourgeoys school board says all of the board's schools will be inspected as soon as possibleafter about 50 students and staff were treated in hospital for carbon monoxide exposure Monday.

School board chair Diane Lamarche-Venne told reporters Tuesday that officials will be checking approximately 80 schools to make sure they have working carbon monoxide detectors.

"We are going through all of our buildings and checking them out," said Lamarche-Venne. "If schools are found to not have detectors in place, they will be installed."

She said a faulty furnace system is believed to have caused the leak atcole des Dcouvreurs in Montreal's LaSalle boroughMonday morning.The heating system had been inspected by a specialized team before winter as per protocol, said Lamarche-Venne.

Fire officials have said the carbon monoxide levels in the school's hallways were as much asfive times higher than levelsthat would normally trigger an evacuation.

School to reopen Wednesday

The school remainedclosed forinspections on Tuesday butwill reopen Wednesday morning.

The school board said corrective measures had been taken on the heating system anda new carbon monoxide detector has been installed.

Additional staff will also be on hand to ensure the return to classes goes smoothly.

Lamarche-Venne said there was a carbon monoxide detector in the school that was inspected in mid-October.

"Everything was functional," she said. "What happened yesterday, obviously it didn't function properly. So we're going to see to that for sure."

She said the school is equipped with both a carbon monoxide detector and a methane detector although neither are mandatory under Quebec's construction code.

'No childrenwere sent in an ambulance alone'

"It's a sad event," said Lamarche-Venne.

She said the school handled the situation well and followed the school board's emergency response guide.

School principals from the area came to help, and "no children were sent in an ambulance alone."

Parents were first notified around noon, about 45 minutes after the initial 911 call was made.Before parents are notified, she said, it is important to make sure the information is accurate.

A second notice was posted to the school's website and transmitted to parents by the end of the day Monday, she said.

"Let's hope we never have to go through that again," she said. "I thinkwhat we learned from through that is people react very quickly when there is an emergency."

'They did a great job'

Angie Velasquez Thornton agrees that the school handled the situation well.

Thornton has two daughters at cole des Dcouvreurs. Evangeline, 6,is in kindergarten, and her big sisterIsabella, 9, is in Grade 4.

The school responded quickly, she said, as the kids didn't even have time to collect their backpacks. They just threwon their winter coats, were shuffled out the door and walkedto anearby school,where they were served pizza.

"I was glad that they reacted so quickly, even if it means our kids' school books are still at school," she said. "I think they did a great job."

Isabella saw for herself how dangerous exposure to carbon monoxide can be.

She was holding hands with a friend as they walked down a hallway when all of a sudden, Thornton said, "her friend fainted and literally fell forward and hit her head."

More sent to hospital overnight

Nine studentsbetween the ages of six and 13lost consciousness at the school.Othersfelt nauseous or dizzy. Somevomited.

On Monday, authorities said35students and eight adults were taken to three hospitals theMontreal Children's, Sacr-Coeurand Sainte-Justine but that number had risen byTuesday morning.

Stephanie Tsigiotis, spokesperson for the Montreal Children's Hospital, said seven more students weretreated and released overnight. Two patients are still under observation in the emergency room, she said.

Lamarche-Venne said almost everyone else hasbeen released from hospital.

"All of them were walking and there wereno life-threatening events or issues with those patients,"Dr. Dominic Chalut, apediatric emergency room doctor and toxicologist, who was working in the Children's emergency ER on Monday.

He told CBC Montreal'sDaybreakthat some of the patients were put in a hyperbaric chamber an oxygen therapy device that promotes delivery of oxygen to cells and organs, reversing the poison's toxicity.

"They all had significant exposure. But, fortunately for them, all of them were very stable. They suffered no significant injury," he said.

Not all schools have COdetectors

A portion of the buildings managed by Montreal's largest school board, theCommission scolaire de Montral (CSDM), are equipped withgas detection devices, including carbon monoxide detectors, according to the CSDM's strategic advisor, Paul Gilbert.

He said the detectors arein garages, boiler rooms, laboratories and other "specialized" spaces and mostly in newer buildings or buildings where the boiler room has been renovated.

"These detectors are inspected and calibrated twice a year by a specialized firm," he said. "An annual update, including a combustion test on all gas and oil equipment is done by another firm specializing in all the CSDM buildings."

The CSDM is currently taking inventory of all of its mechanical equipment and will evaluate itsgas-detection devices, he said.

The English Montreal School Boardhas a "wide array" of gas detectors in its buildings that are checked twice annually, saidEMSB spokesperson Mike Cohen in an email.

At the Commission scolaire de la Pointe-de-l'le, heating systems are subject to regular inspections to ensure their safe operation, saidassistant director Valrie Biron.

She said her board "is doing its utmost to provide a safe environment for its institutions."
