职业性接触毒物危害程度分类方法的探讨

ON CLASSIFICATION METHODS FOR HAZ-ARDS OF OCCUPATIONAL EXPOSURE TO TOXICANT

石油化工装置涉及的化学介质种类繁多,这些化学介质除了存在易燃易爆特性外,还可能对人体造成不同程度的毒性损伤。为了减少并避免人员因中毒引起的伤害,首先需要了解不同化学介质对人体的健康危害,了解混合介质毒物危害程度相关的判别方法,并根据这些职业性接触毒物的危害程度完善相关设计。简要阐述了国内对化学介质毒物危害程度分类的相关标准,并探讨了混合介质毒物危害程度分类方法,以供参考。

There are many kinds of chemical media in-volved in petrochemical plants.These chemical media not only have flammable and explosive characteristics,but also may cause different degrees of toxic damage to human body.In order to reduce and avoid injuries caused by toxicant,it is necessary to understand the health hazards of different chemical media to human body and the classification methods for hazards of mixed media,and improve the relevant design accord-ing to the hazards of these occupational exposure to toxicant.This paper briefly introduces the relevant stan-dards for the classification of occupational exposure to toxicant in China and discusses the classification meth-ods for hazards of occupational exposure to toxicant in mixed media,which may provide some reference.
