Abstract: On February 10, 1989, Employees #1, #2, and #3, were working in the 40 ft by 25 ft paint room of MBC Wood Products in Edwardsburg, MI. At least twenty 55-gallon drums of flammable lacquer, wood stains, etc., were stored in the room. Wood fixtures were being sprayed pneumatically and parts were being dried. Mechanical ventilation was provided by a 36 in. diameter wall-mounted propeller fan which distributed the air poorly because there was no inlet for fresh air supply. A fire ignited at the natural gas furnace adjacent to the mill room and flashed back along a flammable vapor trail to the paint room. Employees #1, #2, and #3 were burned to death in the intense fire that resulted, which totally destroyed the MBC Wood Products facility along with the bakery goods manufacturing facility next door.
