A man in his 40s was killed and another man was seriously injured in an explosion inside a welding shop in the industrial park south of Edmonton on Thursday morning.
The explosion occurred in Nisku around 8:15 a.m. in the morning at Ja-Co Welding at 1304 8 St. at Nisku Business Park.
One person was found dead at the scene, said RCMP. Others were taken to hospitals in Edmonton with serious injuries.
The police did not release the name of the deceased. The RCMP remains in place when the investigation continues.
"Leduc RCMP was called to business in Nisku, [to] report about the explosion on the site there, "the RCMP Constitution Mike Hibbs told CBC News." After arriving, they found a small fire. "
Police said there was no concern for public safety, but community members were asked to stay away from the area.
RCMPs, firefighters, paramedics and Occupational Health and Safety investigators remain in place, police said in a news release around 10am.
Leduc County fire chief Keven Lefebvre said his crew was at the Nisku fire station about 2.5 kilometers away when they felt and heard the force of the explosion.
"We were at the office talking about our daily tasks, what's ahead for the day, and we felt a big bump in the area, soon followed by shipping to this business," Lefebvre said.
"We felt it and heard it in our building so it was a pretty significant explosion. Some of my voluntary respondents who came from Beaumont came and they said they felt it in Beaumont."
Firefighters arrived at the site shortly after and evacuated the building.
After the main search, a decision was made to allow the burning of the acetylene tank to escape, said Lefebvre.
"Once they burn the contents, there is a risk of a smaller explosion … so that's what we have been doing for the last few moments.
"The tanks are burning now. The fire basically goes out."
At 11 o'clock in the morning, acetylene tanks had burned almost all of their fuel and firefighters were preparing to turn the scene into RCMP and OHS.
The cause of the explosion is being investigated, Lefebvre said. The crew will remain in place as needed, he said.
"The initial explosion caused extensive damage so that no one else would come in here for a while until some engineers checked stability," he said.
Nisku is a hamlet and industrial park in Leduc County, about 25 kilometers south of downtown Edmonton.
According to the company's website, Ja-Co Welding is a 110,000-square-foot facility divided into fabrication, office and machine shop.
