确定有机蒸气滤毒盒更换时间的方法概述
|
摘要
有机蒸气是有机溶剂作业场所中一类很常见的职业危害因素,作业者往往需要使用自吸过滤式防毒面具对有机蒸气进行防护。有机蒸气滤毒盒是防毒面具的主要组成部分,确定滤毒盒的有效防护时间并在滤毒盒失效前更换,对保护现场使用者的健康至关重要。本文介绍了影响有机蒸气滤毒盒使用寿命的若干因素,并介绍了目前可用于滤毒盒使用寿命估算的相关技术和方法。使用者应依据使用寿命的估算结果,建立科学合理的有机蒸气滤毒盒更换时间表。
Organic vapor(OV) is a common occupational hazard in workplace where organic solvents are used.Air-purifying respirator is widely used to protect workers from OV vapors. OV cartridge is a major component of the air-purifying respirator, and how to determine its service life and replace it before ineffectiveness is an important assurance of workers' health. In this article, factors that affect the OV cartridge's service life are introduced, as well as technologies and methods that are widely used to determine the service life. Base on the calculation result of service life, a scientific exchange schedule must be built before the use of air-purifying respirator equipped with OV cartridge.
