Status investigation on occupational disease hazards caused by chemical harmful substances in clean workshops of electronic enterprises

Taking four thin-film liquid crystal display（LCD） manufacturers as the research objects, investigates and analyses the occupational disease hazard status in typical workplaces by means of occupational health field surveys and occupational disease hazard factor detection. The results show that the concentrations of chemical harmful substances exposed to workers meet the requirements of occupational exposure limits, and the current adopted occupational disease prevention facilities have a good effect. However, there is no corresponding ventilation and detoxification facility for acetone and isopropanol used in the maintenance operation. According to the characteristics of occupational disease hazards, the related enterprises should formulate corresponding countermeasures for the prevention and control of occupational disease hazards.
