5家采油厂油区联合站工作场所职业病危害因素分析

Actual analysis of occupational hazards in united stations of oil extraction plants

目的分析和评价采油厂油区联合站职业病危害因素程度,加强职业病危害因素关键岗位的控制及预防措施。方法依据《中华人民共和国职业病防治法》、GBZ 159-2004《工作场所空气中有害物质监测的采样规范》、GBZ/T 160.40-2004《工作场所空气中混合烃类化合物的测定方法》、GBZ/T 160.29-2004《工作场所空气中无机含氮化合物的测定方法》、GBZ/T 189.8-2007《工作场所物理因素测量第8部分:噪声》,对5家联合站工作场所危害因素进行检测。结果在分析检测的5家联合站中,绝大多数工种接触的职业病危害因素都符合职业接触限值的要求。1家联合站收油工非甲烷总烃的时间加权平均浓度(CTWA)测定结果超过职业接触限值,不合格率占统计工种的20%,占统计岗位的12%。结论采油厂联合站多数在空旷偏远的山区,居住人群少,对周边环境影响不大,但对企业从业人员重点岗位的职业病危害因素仍需加强管理和控制。

Objective To analyze, evaluate the occupational hazard factors potentially in the united stations of oil extrac- tion plants, identify the critical control points and protective measures. Methods According to Code of Occupational Dis- ease Prevention of PRC, Specifications of Air Sampling for Hazardous Substances Monitoring in the Workplace（ GBZ/T 159 - 2004） ,Methods for Determination of Mixed Hydrocarbons in the Air of Workplace （ GBZ/T 160.40 - 2004）, Methods for Determination of Inorganic Nitrogen Compounds in the Air of Workplace（ GBZ/T 160. 29 - 2004 ） ,Measurement of Physical Factors in the Workplace, Part 8 ： Noise（ GBZ/T 189. 1 - 2007 ）, the evaluation was carried out. Results A majority of oc- cupational risk factors were accorded with the requirements of occupational exposure limits in the 5 plants. The exceeding rate of CTWA for total hydrocarbons was 20% for workers and 12% for work posts. Conclusion Most united stations of oil extraction plants are in the remote mountainous area, they have a little effect on the environment. But the occupational health surveillance of the workers contracted with the key work posts should be strengthened to prevent occupational disea- ses.
