近两年来,工厂企业因作业场所缺氧而造成的伤亡事故屡有发生。据不完全统计已死亡4人,15人入院抢救治疗,给国家和个人带来了不可弥补的损失。我们都知道氧气是空气中的重要组成部分,空气中的含氧量一般在21%左右,如果空气中的氧含量低于16%(即空气中氧的分压低于15.6KP),就会造成人的缺氧、由于缺氧的程度和每个人的体质的不同,所以出现的症状也有所不同,开始时可出现呼吸加深加快、心慌、反应迟钝、头痛、头晕等症状,如不及时脱离现场则很快就会发展为昏厥,窒息甚至死亡。
In the past two years, factories and enterprises due to workplace hypoxia caused casualties have occurred frequently. According to incomplete statistics, 4 people have died and 15 people have been admitted to the hospital for rescue and treatment, bringing irreparable damage to the country and the individual. We all know that oxygen is an important part of the air. The oxygen content of air is generally about 21%. If the oxygen content in the air is less than 16% (ie, the partial pressure of oxygen in the air is lower than 15.6KP), it will be caused Human hypoxia, due to the degree of hypoxia and the different constitution of each person, so the symptoms are also different, the beginning may be deepened breathing, palpitation, unresponsive, headache, dizziness and other symptoms, if not promptly from the scene It quickly develops into fainting, suffocation and even death.
