Abstract:Objective To investigate the cause of an outbreak that with fever, chest tightness, cough as the main symptoms in a production enterprise of solar cells, and to provide suggestrons for the on-site disposal and preventing of re-issued.Methods Clinical features and epidemiological characteristics of the cases were analyzed. The workplaces and treatment of industrial wastes were investigated. Legionella in the throat swab sample and residual water during the processes were detected. Simulation test for poisonous gas from waste incineration was performed using a portable GC-MS detector.Results 52 cases were found and the attack rate was 42.76%.The case distribution was consistent with the characteristics of the outbreak of a homologous exposure. Legionella test result was negative. Clinical symptoms of patients were similar to those of fume fever. In the 12 jobs, the higher the amount of compressed air used in the job, the higher the incidence rate was, and there were statistical correlation between the two (P<0.01).A large number of fluorine-containing solid waste was burned in the evening before the onset of the disease. The compressed air station was downwind from the location of waste incineration, and the simulation test showed that the concentrations of fluobenzene and two- fluobenzene were 435 and 513 mg/m3, respectively.Conclusion The toxic smoke produced by illegal incineration of fluorine-containing solid waste, from the compressed air station into the workshop, causing the workers exposed to organic fluoride poisoning, and then the fluoropolymer fume fever outbreak. Fortunately, we disposed it timely and effectively, and all cases quickly recovered and no secondary occurred.
