目的明确该港口存在或产生的职业病危害因素种类,分析危害程度、产生原因,结合接触水平和采取的防护措施,提出合理的改进措施和建议。方法采用职业卫生现场调查法、职业卫生检测法、职业健康检测法、检查表分析法和综合分析法对危害及防护措施效果进行综合评价。结果该项目在生产过程中可能产生的职业病危害因素主要有柴油、粉尘及噪声。检测结果显示:门机司机岗位、装卸岗位、运输司机岗位、装载机司机岗位、清扫工岗位柴油的时间加权平均浓度均低于最低检出浓度1.5 mg/m~3;装卸岗位、运输司机岗位、装载机司机岗位、清扫工岗位接触的粉尘时间加权平均浓度分别为0.5、0.4、0.4、0.3 mg/m~3,均低于国家规定的职业接触限值;门机司机岗位、运输司机岗位、装载机司机岗位接触的噪声声级分别为69.0、72.5、75.6 d B(A),未超过国家规定的职业接触限值;堆场整理工岗位接触的噪声声级为91.2 d B(A),超过了国家规定的职业接触限值。该项目的总体布局、职业病防护设施、个人使用的职业病防护用品、应急救援、职业健康监护等方面基本符合国家有关规定。结论该项目属于交通运输仓储业中的货运港口,职业病危害风险分类为较重,该港口的防护措施可行,防护效果符合《中华人民共和国职业病防治法》以及相关标准要求。
Aim To clarify the types of occupational hazards that exist or occur in this port, analyze the degree of harm and causes, and put forward reasonable improvement measures and suggestions based on the contact level and protective measures taken. Methods Occupational health field survey, occupational health test, occupational health test, checklist analysis and comprehensive analysis were used to evaluate the effects of the hazards and protective measures. Results The main risk factors of occupational diseases in the production process of the project are diesel oil, dust and noise. The test results showed that the time-weighted average concentrations of driver’s post, loading and unloading post, transportation driver’s post, loader driver’s post and sweeper’s post were all lower than the lowest detected concentration of 1.5 mg / m ~ 3; loading and unloading jobs, , And the time-weighted average concentrations of dust contacted by the post of loader driver and cleaner post were 0.5, 0.4, 0.4 and 0.3 mg / m ~ 3, respectively, which were lower than the occupational exposure limits stipulated by the state; door driver jobs and transportation driver jobs , And noise level of loader driver’s contact was 69.0, 72.5, 75.6 d B (A) respectively, which did not exceed the occupational exposure limits stipulated by the state. The sound level of contact with yard clerks was 91.2 d B (A) , Exceeding the national limit of occupational exposure. The overall layout of the project, occupational disease protection facilities, personal use of occupational disease protection supplies, emergency rescue, occupational health care and other aspects of the basic line with the relevant state regulations. Conclusion The project belongs to freight port in the transportation and warehousing industry. The risk of occupational disease is classified as heavy. The protective measures at this port are feasible and the protective effect conforms to the Law of the People’s Republic of China on Occupational Disease Prevention and Control and the relevant standards.
