A 51-year-old man who suffered severe burns in a boiler explosion at a heating plant below the Supreme Court of Canada Monday has died, Ottawa police said Tuesday.

 

The man, whose name police have not released, suffered burns to 60 per cent of his body after what Ottawa Fire called a “catastrophic event” shortly after noon.

 

“Right now, it’s still under investigation,” said Ottawa Fire District Chief John Gagnon.

 

While Ottawa Fire Services is leading the investigation, police, the Ontario Fire Marshal’s office and the federal ministry of labour are also looking into what caused the explosion, said Gagnon.

While investigators had initially worried about the possibility of collapse, an investigation Tuesday concluded that the four-storey structure is in no danger of collapse.

“The building is salvageable. It’s still in good shape,” Gagnon said.

Investigators will continue to look at the five remaining high-pressure steam boilers — which provide heat to government buildings along Wellington Street, including Parliament Hill — to see what caused the explosion, which also injured two others.

“Whether it’s a fuel explosion or a mechanical explosion, the force of the explosion followed up to the western wall and through the vents,” said Gagnon.

Damages are estimated at $2 million.
