On March 27, 1998, an explosion occurred in a wood dust collection system. Employees #1 and #2 sustained multiple contusions, but did not require hospitalization. Apparently a fire had started in the metal shell containing a suction booster/blower, and sent sparks into the dust collection system through a mating flange gasket. The flange of the booster was square, with eight bolt holes equally spaced around the flange. Four of the bolt holes were used to hold the flange and transition duct together; the other four holes were covered by the mating gasket. Apparently, the external fire burned through the gasket material and was drawn into duct #17 and then into the plenum. A second possibility is that the external heat from the fire transferred to the internal surfaces of the blower and this sent sparks into the dust collection system.
