Abstract: At 2:40 p.m. on May 5, 1985, just before the shift change, Employees #1 through #5 (three from the first shift and two from the second shift) were trying to break up a clog in a BD-2 crossover conveyer. The employees had opened the access plates on top of the 18-in. screw conveyor and were using aluminum rods and water hoses to break up the clog, which resulted when a chain drive on the conveyer broke. The clog broke up suddenly and a slurry of hot water and wood pulp gushed out the open access plates. Employees #1 through #5 sustained first-, second-, and third-degree burns over 35 to 70 percent of their bodies. Employee #1 was killed, and Employees #1 through #4 were hospitalized.
