REGINA – Investigators are getting closer to pinpointing the source of an explosion at Regina’s Co-op refinery.
Fire marshal Randy Ryba says the blast site is being inspected and crews are sifting through debris and other material.
Ryba says the blast is believed to have been set off when products lighter than gas were ignited in a reactor.

“They are flammable, which packs even more energy and … if that energy is confined within a space or area, and you have a credible source of ignition … you’re going to get an overpressure,” he said Tuesday.
But there are no definitive answers yet as investigators have not been able to get to the reactor’s platform. Ryba said the area is delicate and explosion crews have to work slowly and carefully.
“We have to make sure that some of the items that are strewn around the area are not part and parcel to the potential cause of this explosion.”
The blast on Christmas Eve could be heard around the city.
There is no timeline for when the investigation will be completed.
