Revelstoke RCMP Sgt. Chris Dodds said in a press release Monday that the cause of a trailer explosion Sunday night isn't suspicious and isn't being investigated as a criminal act.

The trailer contained four snowmobiles and was attached to a truck parked behind the Sandman Hotel. The trailer exploded just before 8:00 p.m. and caught on fire. Fire chief Steven DeRousie says the fire department was called at 7:55 p.m.

The explosion was felt in houses all over Revelstoke, but nobody was hurt. One double-paned window on the second floor of the hotel was broken, and two vehicles were damaged, Dodds said.

A hotel guest was clearing snow off his car in the parking lot on Monday morning. His car was undamaged. He was in his room at the time of the explosion and said it was a big boom.

DeRousie said it took 15 firefighters 15 minutes to put out the fire. They were trying to stop it from spreading to the truck, which had jerry cans in it.

Revelstoke Fire Services sent a report to the Office of the B.C. fire commissioner, DeRousie said. They will work with the RCMP to investigate the cause of the explosion. It could months for the results of the investigation to be released, and they may not discover the cause, he said.

DeRousie suspects the contained space of the trailer made some kind of leaking fuel vapours volatile, and a something sparked which caused the explosion. He didn't know if the snowmobiles had gas in their tanks. The trailer was heated by diesel.

This type of explosion is very rare, DeRousie said, especially given how often machines are transported in enclosed trailers.

He said if people smell gasoline, they should always find out the source of the smell. Ventilate the space, and make sure nothing happens that would cause a spark.
