New video shows incredible force of Wheatley, Ont., explosion

A newly surfaced video of the Wheatley, Ont., explosion showsthe incredible force of the blastthat hitthe small town's core last summer.

It is also bringing back tough memories for residents of the community, located about 70kilometres southeast of Windsor in the Municipality of Chatham-Kent.

"That was our village, that's where we all went to gather," saidRebecca Lamb of the downtown intersection seen in the 44-second video.Lamb and her husband remain out of their home,which is nearby and was badly damaged.

"It brought back a lot of very, very sad times."

The video, obtained by CBCWindsor this week, was captured by a security camera at a business across the street and gives the clearest view yet of the Aug.26, 2021, explosion.

It shows the moment, at 6:13 p.m. ET, the powerful blast sent a cloud of smoke and debris flying intothe air. Bystandersare seen fleeing while firefighters, who were responding to elevated gas level alarmsin the area, immediately begin responding.

Rich Meier is a U.S. based expert in fire and explosion investigations. He says the mixture of gas and air at the time of the explosion was likely just right for something really bad to happen.

She says the video doesn't show how high the debris was thrown into the air.

"It went way up in the air, it went straight up," she said. "Things were flying in the air, a lot of insulation, a lot of everything. I saw two-by-fours, just woo flying up."

MarioAmaralwas driving a black truck that can be seen in the video on his way to pick up a bag of milk at the Circle K.

He says he hit the deck in his truck the moment he heard the blast. He felt debris hit his truck before lifting his head back up and driving off.

"That's when I saw that cloud of dust coming," he said. "I didn't care if it was a red light or not, I was getting the heck out of there."

"I can't believe nobody got killed."

Based on what's in the video, the mixture of gas and air at the time of the explosion was likely just right for "something really bad to happen,"said Richard Meier,afire and explosion expert based in Florida.Meier is not involved in the investigation.

"It's kind of theGoldilockscombination," he said of the likelygas/air mixture, addingit takes an extremely small spark to ignite an explosion.

"A cat walking under a couch ... and little static electricity can set it off," he said.

"It takes very little energy. So if there's a candle, a pilot light, somebody clicking on a light switch, all of those are competentignition sources to ignite a flammable air-gas mixture like that."

Two abandoned wells have been found in the area and a team from the province continues to investigate whether they are the sourceof the leak suspected to have caused the blast, or if it comes from elsewhere.

Municipality officials said earlier this week the goal of work being done in the area is to permanently stop the gas leak, to reduce the evacuation zone and find a way to allow residents and businesses to get back to their buildings.

CBCNews requestedto speak withChatham Kent Fire Services but officials declined, saying theycould not speak to the video as it is part of an active investigation.
