某天然气井站地面集输工程职业病危害预评价

Pre evaluation of occupational hazards in surface gathering and transportation engineering of a natural gas station

目的分析、识别拟建项目可能产生的职业病危害因素及防护措施,提出合理可行的职业病防护补充措施及建议。方法选择与该项目类似的工程进行类比调查,采取检查表法、类比法、定量分析法进行定性和定量评价。结果类比检测结果显示:噪声共检测3个点,均低于85.0 dB(A);化学毒物主要检测项目为硫化氢,共检测2个点,均符合要求。结论拟建项目存在的主要职业病危害因素为甲烷、硫化氢等,属于职业病危害较重建设项目,企业应按照补充措施及建议进行完善。

Objective To analyze the possible occupational hazards and protective measures of the proposed project,to identify and put forward reasonable and feasible supplementary measures for occupational disease prevention,and put forward some suggestions.Methods Similar project was selected to carry out the analogy investigation,check table method,analogy method,quantitative analysis method were applied for qualitative and quantitative evaluation.Results The results of the simulation showed that the noise was detected at 3 points,which were lower than 85.0 dB（A）,and the main test items of chemical toxicants were hydrogen sulfide,which were detected at 2 points.Conclusion The main occupational hazard factors of the proposed project are methane,hydrogen sulfide and so on,which belong to the construction project with serious occupational hazards.It should be improved by enteprises according to the supplementary measures and suggestions.
