摘要
密闭空间是一种通风不良、有毒有害物质极易堆积的空间。由于石油化工行业的特殊性,日常要进行众多的密闭空间作业。密闭空间的环境复杂,危险因素众多,且一旦发生危险,施救难度大,因而在作业前对密闭空间有毒有害物质分析是十分有必要的。本文首先介绍了密闭空间及其典型有害物质,然后详细叙述了对其的采样和分析方法,以期提供借鉴作用。
A confined space is a space with poor ventilation and easy accumulation of toxic and harmful substances.Due to the particularity of petrochemical industry,many confined space operations are needed daily.The environment of confined space is complex,there are many dangerous factors,and once danger occurs,it is difficult to rescue,so it is very necessary to analyze toxic and harmful substances in confined space before operation.This paper first introduces the confined space and its typical harmful substances,and then describes its sampling and analysis methods in detail,hoping to provide reference.
