Description:In response to a confidential request, an investigation was begun into possible hazardous working conditions at the Little Blue Valley Sewer District wastewater treatment facility (SIC-4952), Independence, Missouri. Complaints received included gastrointestinal disturbances, sore throats, fatigue, headaches, eye irritation, and coughing among those working in the belt press room. Personal breathing zone samples for total particulate ranged from 0.03 to 0.28mg/m3. Measurements also indicated a range of 2.50 to 6.82 endotoxin units per cubic meter of air. Sludge samples containing 40% solids had the highest concentrations and largest variety of volatile organic compounds. Analysis indicated that the belt room workers were exposed to hydrogen-sulfide (7783064) at concentrations which exceeded the NIOSH 10-minute ceiling of 10 parts per million (ppm) in eight of 13 breathing zone samples
three also exceeded the OSHA limit of 20ppm. The author concludes that workers were overexposed to hydrogen-sulfide. The author recommends that continuous monitoring be provided for employees in or around the belt press room to evaluate hydrogen-sulfide exposure levels. Engineering controls should be used to reduce hydrogen-sulfide levels. Until the improvements are made, workers should use respiratory protection.
