Work Safety in Waste Treatment

Abstract

Accident risks in waste treatment were studied at five sanitary landfills, two plants using mainly manual sorting and one incineration plant in southern Finland. Work hazards were detected by means of safety analysis. In addition, accident statistics were used. Work safety problems were found at all work stages. At the sanitary landfills, the major safety problems were posed by operation of the compactor or other machinery and by hazardous wastes. In waste sorting, common problems are odour and dust, lacerations and back injuries. Falling into the waste compactor or paper silos may cause fatal injury and its probability was also high. The highest noise level measured was 97 dB(A). In waste incineration, the most serious hazards were caused by fires, clogging of the funnels and cleaning of the grate. Most deficiencies in work safety can be remedied at a moderate price. The corrective measures involve technical solutions, working methods, supervision, training and occupational health services. The accident rates for workers in the four waste treatment plants were slightly lower than the average for industry.
