Dust explosions and the Burns Lake mill

Concerns are being raised that wood dust could have been the cause of the giant explosion and fire at a Burns Lake sawmill late last week.

Several workers have said pine dust regularly clouded the air in the mill; A WorkSafe BC report showed 10 samples taken at the mill in November found unacceptably high dust levels in the basement cleanup area -- citing respirtory concerns.
