An accident in a plant for solvent recovery from solvent-contaminated wastes was examined. An experimental investigation of the accident was carried out using calorimetric and thermogravimetric techniques. The immediate cause of the accident was an unforeseen exothermic decomposition reaction. The main underlying cause of the accident was the absence of safety culture in the plant management, that resulted in the lack of a testing procedure to evaluate the thermal stability of the process feed. A simplified screening procedure based on differential scanning calorimetry was used in order to test the thermal stability of the nonvolatile fraction of the solvent-contaminated wastes present on the plant in order to be processed. More than 75% of the samples examined showed exothermal decomposition phenomena starting at temperatures higher than 100 degrees C. These phenomena were common to solvent wastes that originated from a number of different industrial activities. Thus, the thermal instability of the process feed is one of the main problems in solvent recovery operations. Our analysis of the accident suggested that the safe operation of waste solvent recovery processes requires an accurate characterization of the thermal stability of the process feed. Process safety is also increased by an adequate emergency vent and an accurate control of operating temperature, that may be reduced operating under vacuum. Safety devices may also include a water supply for emergency quench.
Agriculture is one of the most hazardous industries in the United States, with the second highest work-related fatality rate during 1992-1996 (21.9 deaths per 100,000 workers). During 1992-1995, 155 deaths were reported among agricultural workers aged < or =19 years; 64 (41%) of these youths were working in their family's business . In Minnesota during 1992-1996, agriculture had the highest fatality rate of any industry (21.3 per 100,000 workers). To characterize agriculture work-related deaths among youths in Minnesota during 1994-1997, the Minnesota Department of Health (MDH) analyzed data from the state's Fatality Assessment and Control Evaluation (FACE) program. This report presents five cases of agriculture work-related fatalities among youths in Minnesota.
First, the paper presents a brief summary of the French actual regulation on installations registered for the protection of the environment and covered by the Seveso I Directive. Then the paper discusses research and development needs for a sound implementation of the Directive, and for the new requirements on safety reports established by the Seveso II Directive. Further, it discusses issues connected with coverage of hazardous activities, learning from accidents, technical and organisational measures (safety management systems and emergency response) and human factors. The conclusions stress the need for networking and dissemination of accident investigations, development of safety management systems, and research on cognitive ergonomics and psychology related to the decision making and interventions of the operator.
