目的对某陶瓷洁具生产项目进行现状评价,确定职业病危害因素关键控制点,制定职业病危害预防控制的有效对策。方法采取职业卫生学调查、检查表法、检测分析、定量分级相结合的方法对该项目进行现状评价。结果在生产过程各个环节中产生的主要职业病危害因素有粉尘、噪声、高温、一氧化碳、二氧化碳等。总尘检测显示球浆、注浆、施釉和球釉TWA分别为1.48、1.24、1.34、1.01 mg/m3,不符合职业卫生限值要求,其危害等级均为Ⅰ级。噪声检测显示球浆、施釉和球釉的LEX,8 h分别为86.9、89.5、93.2 dB(A),不符合职业接触限值要求,其危害等级分别为Ⅰ级、Ⅰ级、Ⅱ级。球浆、注浆、施釉及球釉作业岗位为职业病危害因素关键控制点。结论该项目属职业危害严重项目,且需要整改。
Objective To evaluate the status quo of a ceramic sanitary ware production project, determine the key control points of occupational hazards and formulate effective countermeasures for the prevention and control of occupational hazards. Methods Occupational hygiene survey, checklist method, detection and analysis, quantitative grading were used to evaluate the status of the project. Results The main occupational hazards in the production process are dust, noise, high temperature, carbon monoxide, carbon dioxide and so on. Total dust test showed that the plasma, grouting, glazing and glaze TWA were 1.48, 1.24, 1.34, 1.01 mg / m3, respectively, which did not meet the occupational health limit requirements. The noise test showed that the LEX of glazing, glazing and glaze were 86.9, 89.5 and 93.2 dB (A) for 8 h respectively, which did not meet the requirements of occupational exposure limits. The hazard classes were Grade I, Grade I and Grade II, respectively. Spherical, grouting, glazing and glaze jobs occupational hazards as a key control point. Conclusion This project is a serious occupational hazard project and needs rectification.
