目的了解江西省油库职业病危害因素的分布情况,为制定防控措施提供依据。方法通过现场职业卫生学调查对职业病危害因素进行识别,依照国家标准方法对职业病危害因素进行采样和检测,并依据《工作场所有害因素职业接触限值》(GBZ 2-2007)对检测结果进行评价和分析。结果油库作业环境中存在的主要职业病危害因素为汽油、苯、甲苯、二甲苯等烃类化合物、盐酸以及噪声等。油库汽油浓度最高为52.4 mg/m3,低于国家标准限值;苯浓度最高可达9.07 mg/m3,接近国家标准限值10 mg/m3;油库消防泵房作业工人接触噪声强度最高可达84.13 d B(A),发电机房作业工人高达84.99 d B(A),接近国家标准限值85 d B(A);其他职业病危害因素的浓度均符合国家标准限值要求。结论苯和噪声是油库职业病危害关键控制点,应采取相应的防控措施。
Objective To understand the distribution of occupational hazards in Jiangxi oil depots and provide the basis for the development of prevention and control measures. Methods Through occupational health survey on the spot, occupational hazards were identified, the occupational hazards were sampled and tested in accordance with the national standard method, and the test results were evaluated according to “Occupational Exposure Limit of Hazardous Locations in the Workplace” (GBZ 2-2007) And analysis. Results The main occupational hazards that exist in the operation environment of oil depot are hydrocarbon, benzene, toluene, xylene and other hydrocarbons, hydrochloric acid and noise. The gasoline concentration in oil depot was 52.4 mg / m3, which was lower than the national standard. The benzene concentration was up to 9.07 mg / m3, close to the national standard limit of 10 mg / m3. The contact noise intensity of workers in depot fire pump reached 84.13 d B (A). The number of workers in generator room was as high as 84.99 d B (A), close to the national standard limit of 85 d B (A). Other concentrations of occupational hazard factors all met the national standard limits. Conclusion Benzene and noise are the key control points of occupational hazards in oil depots. Corresponding control measures should be taken.
