摘要
目的了解某集装箱运输港区工作场所存在的主要职业病危害因素水平与分布,提出预防措施及关键岗位操作时的注意事项。方法依据《工作场所空气中有害物质监测的采样规范》《建设项目职业病危害控制效果评价技术导则》等相关规范和标准,通过现场调查和检测对某集装箱运输港区工程项目的职业病危害进行分析与评价。结果存在的主要职业病危害因素为一氧化碳、二氧化碳、工频电场、噪声和高温;该港区码头、堆场工作场所中一氧化碳、二氧化碳的时间加权平均容许浓度分别为1.0 mg/m3、1.3 mg/m3,短时间接触浓度分别为1 125 mg/m3、1 080 mg/m3,均远低于国家卫生接触限值的要求。各个监测点工频电场、噪声、高温合格率均达100%。结论该项目属于职业病危害较重的建设项目,采取的职业病危害因素防护措施可行,有效。但仍应加强危险品装卸区、锅炉房、污水处理站的日常维护,防止职业病的发生。
Objective To understand the level and distribution of occupational hazards in the workplace of container trans- porting port and provide preventive measures and points for attention at work. Methods According to Specifications of Air Sampling for Hazardous Substances Monitoring in the Workplace（ GBZ 159 -2004） and Technical Guidelines for Effect As- sessment for Occupational Hazard Control in Construction Project（ GBZ/T 197 -2007 ）, occupational hazards in the work- place of container transporting port were evaluated and assessed by means of surveillance. Results The main occupational risk factors were carbon monoxide, carbon dioxide, power frequency electric field, noise and high temperature. The time weighed average concentrations of carbon monoxide and carbon dioxide were 1.0 mg,/m^3 and 1.3 mg/m^3, and the short - term exposure concentrations of carbon monoxide and carbon dioxide were 1 125 mg/m^3 and 1 080 mg/m^3 , respectively, which were in accord with the requirements of relative standards. Qualified rate of power frequency electric field, noise, heat stress accorded with the requirements of relative standards was 100% in the monitoring points. Conclusion This construc- tion project was ranked as a serious project. The protective measures on occupational hazards in the project are feasible and effective. But daily maintenance in the workplace of loading area of hazardous material, boiler room and waste water treat- ment plant should be strengthened to prevent occupation disease.
