Investigators wait to find out what caused fire and explosion at B.C. house

SURREY, B.C. – Fire investigators are waiting to enter a house in Surrey, B.C., to determine the cause of a blaze and explosion.

Assistant fire chief David Burns of the Surrey Fire Service says investigators are waiting for a structural engineer to determine whether the building is safe to enter.

He says three adults were inside the home when the blast occurred Saturday afternoon but they escaped without injury.

Burns says the explosion caused significant damage, preventing crews from getting too far into the house.

He says an inspection could begin as early as Monday, depending on the engineer’s assessment.

Burns says early indications suggest the blast may have involved propane but that has yet to be determined.
