【摘要】：目的了解油库工作场所职业病危害因素种类和水平。方法对2013年河南省23家油库工作场所苯、甲苯、溶剂汽油和噪声等职业病危害因素进行采样分析,根据相关标准和规范进行评价。结果油库的铁路卸油栈桥和铁路卸油泵房工作岗位均有出现苯、甲苯和溶剂汽油短时间接触浓度(CSTEL)超标,超标率均为2.5%(1/40);公路收发油台、公路收发油泵房和油库化验室工作岗位均出现溶剂汽油CSTEL超标,超标率均为5.0%(2/40)。汽油泵房工和发电机工接触的8 h等效声级(LEx,8h)最大值分别为91.9和86.6 d B(A),均超标,超标率分别为12.5%(1/8)和6.2%(1/16);中转油泵工、收/发油泵工、铁路卸油工和消防泵工的LEx,8h最大值分别为84.5、84.3、83.6和83.5 d B(A),接近职业接触限值85.0 d B(A)。结论河南省油库工作场所主要职业病危害因素有苯、甲苯、溶剂汽油和噪声,应加强职业卫生管理,预防发生职业病。
[Abstract]:Objective to investigate the types and levels of occupational hazards in the workplace of oil depots.Methods the occupational hazard factors such as benzene, toluene, solvent gasoline and noise in 23 oil depots in Henan Province in 2013 were sampled and analyzed, and evaluated according to the relevant standards and specifications.Results benzene was found in the railway oil unloading trestle and the railway oil unloading pump room. The concentration of toluene and solvent gasoline in short time contact with CSTELs exceeded the standard, and the rate of exceeding the standard was 2.5% / 40%.In both the pump room and the laboratory of the oil depot, the solvent gasoline CSTEL exceeded the standard, and the rate of exceeding the standard was 5. 0% or 2 / 40%.The maximum values of LEx1 for railway oil unloader and fire pump were 84.5g / 84.3g / 83.6 and 83.5 d / 83.5 days, respectively, which were close to the occupational exposure limit of 85.0 d / s.Conclusion the main occupational hazard factors of Henan oil depot are benzene, toluene, solvent gasoline and noise. Occupational health management should be strengthened to prevent occupational diseases.
