目的识别、分析与评价某双酚A优化改造拟建项目可能产生的职业病危害因素,并提出可行性的防护补充措施。方法采用检查表法、类比法相结合的原则,对拟建工程可能产生的职业病危害及防护措施进行定性及定量评价。结果该拟建项目正常生产过程中识别的职业病危害因素有化学毒物、粉尘和物理因素。其中类比检测化学毒物、粉尘、高温等均符合接触限值要求,2个检测点噪声超标8 h等效噪声强度分别为91.2和95.3 dB(A)。结论该项目为职业病危害一般的建设项目,在正常生产运行过程中可能存在的职业病危害因素可以预防和控制,从职业病防护角度分析,该拟建项目是可行的。
Objective To identify, analyze and evaluate the potential hazards of occupational diseases caused by the proposed project for the optimization and reconstruction of a bisphenol A and to provide feasible protective and complementary measures. Methods The principle of combination of checklist and analogy was used to evaluate the potential hazards of occupational diseases and protective measures in the proposed project. Results The occupational hazards identified in the normal production of the proposed project were chemical poisons, dusts and physical factors. Among them, the analog detection of chemical poisons, dust and high temperature met the contact limit requirements. The equivalent noise intensities of the two detection points exceeding 8 h were 91.2 and 95.3 dB (A) respectively. Conclusion This project is a general construction project with occupational hazards. The occupational hazards that may exist during normal production and operation can be prevented and controlled. From the perspective of occupational disease protection, the proposed project is feasible.
