秋天已经过去,寒冬即将来临,此刻在广大农村和乡镇企业中,煤气中毒事件屡有发生,造成人身伤亡,给个人,家庭和社会带来灾难和损失。为什么煤气会造成如此重大的中毒危害呢?又怎样预防煤气中毒呢?我们通常所说的煤气中毒实际上就是一氧化碳中毒。一氧化碳是一种无味、无嗅、无色的气体,燃烧的一氧化碳在空气中呈兰色火焰。当含碳物质,如煤,在空气中燃烧时如缺少氧气,就可产生一氧化碳而使人中毒。中毒的程度与空气中一氧化碳的浓度有一定的关系,据文献报导:当吸入浓度为每升0.43毫克的一氧化碳4小时,可引起头痛、头晕;吸入浓度为每升0.46毫克2小时头痛剧烈;
Autumn has passed and the winter is approaching. In the vast majority of rural areas and township and village enterprises, gas poisoning accidents have occurred frequently, causing personal injury and death, bringing disasters and losses to individuals, families and the community. Why gas will cause such a major poisoning hazard? How to prevent gas poisoning? We usually say that gas poisoning is actually carbon monoxide poisoning. Carbon monoxide is a tasteless, odorless, colorless gas that burns with a blue flame in the air. When carbonaceous material, such as coal, is burned in the air, such as lack of oxygen, it can produce carbon monoxide poisoning. The degree of poisoning and the concentration of carbon monoxide in the air has a certain relationship, according to the literature: when inhaled concentration of 0.43 mg per liter of carbon monoxide for 4 hours, can cause headache, dizziness; inhalation concentration of 0.46 mg per liter for 2 hours severe headache;
