基于LEC法的化工类高校实验室危险源辨识

Identification of Hazard Sources in University Laboratories Based on LEC Method

实验室人员复杂密集和流动性大等诸多因素和近年多起实验室安全事故使实验室危化品安全管理已成为社会广泛关注的重点。面对危险化学品事故频发的现状,对高校实验室化学品事故进行风险评估与分级显得尤为重要。危险化学品具有易燃易爆、腐蚀、毒害和放射性等特性会对人体造成直接伤害,处理不当还会引发安全事故。为提高高校实验室人员对风险的认识,提高其安全意识,通过对实验室危险源辨识,确定危险等级,采取相应的措施,防止或减少同类生产安全事故的发生。

Many factors such as complex laboratory personnel and many laboratory safety accidents in recent years have made the safety management of hazardous chemicals in laboratories become the focus of the society.In the face of the frequent occurrence of dangerous chemical accidents,it is particularly important to conduct risk assessment and grading of chemical accidents in university laboratories.Hazardous chemicals are flammable,explosive,corrosive,toxic and radioactive,which can cause direct harm to the human body.Improper handling can also cause safety accidents.In order to improve the awareness of risk among college laboratory personnel and improve their safety awareness,the hazard sources of the laboratory were identified,their hazard levels were determined,and corresponding measures to prevent or reduce the occurrence of similar production safety accidents were put forwrd.
