A sawmill was destroyed in an explosion, killing two and injuring 19. A welder said several days of very cold weather meant workers had to thaw pipes with torches and some of those pipes contained various gasses. Another worker said he was concerned about the build up of sawdust in the mill. And the chief of the Babine Lake Nation noted that the mill didn’t have a JHSC. The RCMP, WorkSafeBC and the BC Safety Authority are investigating.
