氧气报警器报警范围是多少?
氧气作为人体的必须元素,空气中氧气的含量对人体非常重要。在一般环境中,人们吸进的空气,按照体积计算,氧气占20.93%,二氧化碳占0.03%;呼出的气体中,二氧化碳上升约占3.5%,氧气下降约占17%。虽然,氧气是空气的重要组成部分,但并不是说它是无毒的,氧气含量过低过高都会导致一定的危害,因此,我们需要安装氧气报警器。那么您知道氧气报警器报警范围是多少吗?下面逸云天小编为您介绍:

正常人体只需要一定浓度的氧,氧的浓度过高或过低都对人体有害:
氧气浓度(%体积) ---征兆(大气压力下)
>23.5%---富氧,有强烈爆炸危险
20.9%---氧气浓度正常
19.5%---氧气最小允许浓度
15-19%---降低工作效率,并可导致头部、肺部和循环系统问题
10-12%---呼吸急促,判断力丧失,嘴唇发紫
8-10%---智力丧失,昏厥,无意识,脸色苍白,嘴唇发紫,恶心呕吐
6-8%---8分钟致命;
4-6%---40秒内抽搐,呼吸停止,死亡
100%---致命/6分钟
50%---致命/4-5分钟经治疗可痊愈
因此,在一般情况下,氧气报警器报警范围一般是19.5%vol和23%vol,低于19.5%vol和高于23%都会报警,氧气浓度数值测量范围一般是0-30%vol,一般在19.5%vol-23%vol之间都算正常。在氧气使用场所可以配置氧气报警器,实时对现场氧气浓度进行检测,保证现场人员安全。
