Beetle-kill and green wood dust explosive: WorkSafeBC

Dust from green wood, as well as pine beetle wood, could have contributed to two fatal explosions at the Burns Lake and Prince George sawmills earlier this year, according to a scientific analysis commissioned by WorkSafeBC.

WorkSafeBC said that tests results from samples sent to a U.S. laboratory show that both types of wood dust pose a high risk of explosion under very dry conditions.

The tests were done following speculation that beetle-kill wood dust was a potential fuel source in one or both of the the explosions.
