• Description:
  In response to a request from the Stone Container Corporation located in Missoula, Montana, an investigation was made of possible hazardous working conditions at that site. The facility produced paper products for use in cardboard containers. Workers were experiencing headaches and light headedness when they were inside the color removal unit. The unit clarified up to 10 million gallons per day of wastewater before it was discharged into an adjacent river. Thickened sludge was burned in the recovery boilers as a supplemental fuel. The major exposures were to hydrogen-sulfide (7783064) (H2S). Dust exposures were below any occupational health evaluation criteria. The authors recommend that outside air in the color removal unit should be kept to a maximum, whenever weather permits, to prevent the accumulation of H2S. A confined entry procedure should be used when the tanks are drained, and workers are entering them for repair work. A stationary monitor for H2S should be considered on the catwalk adjacent to the tank which is the major source of H2S. An alternative method for cleanup in the warehouse should be considered as the use of compressed air for blowing down equipment should be discontinued.
