某气田甲醇污水处理工程职业病危害及防护对策

Gas field methanol wastewater treatment engineering occupational hazards and protection countermeasure

目的了解气田甲醇污水处理工程中职业病危害因素及其存在的主要环节,提出针对性的防护对策。方法采取现场职业卫生学调查,根据国家现行职业卫生标准进行职业病危害因素检测。结果甲醇污水处理工程存在的主要职业病危害因素为天然气、甲醇、氢氧化钠、一氧化碳、二氧化碳、C6～C25烃类,噪声、高温。该污水处理工程存在的主要职业病危害均未超出国家标准。有毒物质检测合格率为100%,有害物理因素检测合格率为100%。结论为防范发生职业中毒事故发生,应加强日常职业卫生管理和非正常作业情况下的应急防护。

Objective To understand the gas field methanol wastewater treatment engineering of occupational hazards and main link,puts forward the protective measures.Methods According to the current national occupation hygiene standards,occupational risk factors were detected with field investigation.Results The main occupational hazards included natural gas,methanol,sodium hydroxide,carbon monoxide,carbon dioxide,C6-C25 hydrocarbons,noise and high temperature.The main occupational risk factors accorded with the national standards.Qualified rate of toxic substances was 100%,the qualified rate of harmful physical factors was 100%.Conclusion In order to prevent occupation poisoning accident,it is suggested to strengthen the daily occupation health management and the normal operation of emergency protection.
