WorkSafeBC cautions mills to be 'vigilant'

British Columbia sawmills were warned Thursday that dust from both green wood and beetle-killed pine poses a high risk of explosion under the right conditions.

WorkSafeBC officials said it was already known that dust from beetle-killed timber had an explosive capacity, but recent test results from a U.S. lab showed dust from trees that were alive when they were felled also posed an explosion risk.

The findings are part of WorkSafeBC's investigation into two sawmill explosions in northern B.C. that killed four workers and injured dozens of others.
