如今使用煤气当燃料的家用设备越来越多,有煤气灶具、煤气取暖器和煤气热水器等,它们具有使用方便、热效率高和干净等优点,但也存在易燃、易爆、有毒的缺点,弄不好就会引起事故,甚至招来杀身之祸。 近年来,据消防部门统计分析,煤气引发的事故大致可分为两大类:一类是人身中毒,由于煤气成份里含有约10％的一氧化碳气体,一旦泄漏出来,在空气中一氧化碳含量达0.1—0.12％时,被人体吸入肺部,就会进入血液循环系统,使人的肌体组织严重缺氧,导致窒息死亡,所以煤气中毒确切地说是一氧化碳中毒。
Nowadays, there are more and more household appliances that use gas as fuel, such as gas cooker, gas heater and gas water heater, which are easy to use, high in thermal efficiency and clean, but flammable, explosive and toxic. If you do not get it well, it will cause accidents and even lead to the disaster of killing yourself. In recent years, according to the fire department statistical analysis, gas-induced accidents can be broadly divided into two categories: one is personal poisoning, as the gas composition contains about 10% of the carbon monoxide gas, once leaked, the carbon monoxide content in the air up to 0.1 -0.12%, the body inhaled into the lungs, it will enter the blood circulation system, making the human body tissue hypoxia, leading to suffocation, so gas poisoning is exactly carbon monoxide poisoning.
