The family had been cooking steaks on an outdoor barbecue and they were inside when it exploded.
Doug Hamer, the Riverview Fire Rescue chief, said the family members escaped, but didn't even have time to get their shoes on.
"The whole second floor is burned off it. There's fire damage on every floor of the house," Hamer said.

The Riverview firefighter said it was a good thing the family was inside when the explosion happened.

"And any items like that shouldn't be left unattended. It's not a good habit to put your cookables on and walk away."
I see the general case there, but wouldn't someone be dead if they'd been standing beside that barbecue when it blew up? (Ok, Ok, the reports from the neighbours said there was a fog (I'd assume propane) that formed around the BBQ beforehand, but if that hadn't been noticed, or just mistaken for more smoke?)
