摘要
通过研究毒物伤害准则进而界定有毒气体危害浓度,对有毒气体泄漏扩散后的危害区域进行分级划分,以采取相应的防护措施,最大限度的即时有效的减轻有毒气体对人员的伤害。最后,以氯为例,对比其在不同伤害准则下危害区域划分临界浓度标准值,数值差别较大,因此在使用时应根据实际情况加以判断,选择最适当的标准来划分危害区域。
According to study on the toxicant harm criteria, hazardous concentration of toxic gas can be confirmed. Under these criteria, hazardous zones can also be graded, so as to take the corresponding protective measures, and maximize the injury and harm to human timely and effectively. The comparison of the critical concentration of chlorine hazardous zones under different criteria shows that values are different. So the most appropriate criteria to determine the hazardous zone should be judged in accordance with the practical situation.
