二氧化碳灭火器的生物范围也是有限的，假如说出现不一样的火灾，往往采用的灭火器也要有不同的规定。家庭主人如果不了解这些问题，可以多关心二氧化碳灭火器可以扑救钾钠镁金属火灾，看看二氧化碳灭火器使用须知，掌握正确的使用方案，从而发挥更好的使用效果，就能减少各种使用的问题。

The biological range of carbon dioxide fire extinguishers is also limited. If there is a different fire, the fire extinguishers often used should also have different regulations. If the home owner does not understand these problems, he can pay more attention to the carbon dioxide fire extinguisher, which can put out potassium sodium magnesium metal fires. Look at the instructions for the use of carbon dioxide fire extinguishers, master the correct use plan, so as to play a better use effect, and reduce various use problems.

二氧化碳灭火器不可以扑救钾，钠，镁金属火灾。二氧化碳灭火器适用范围：有流动性好、喷射率高、不腐蚀容器和不易变质等优良性能，用来扑灭图书，档案，贵重设备，精密仪器、600伏以下电气设备及油类的初起火灾设计。

Carbon dioxide fire extinguishers cannot extinguish potassium, sodium, magnesium metal fires. Scope of application of carbon dioxide fire extinguisher: it has excellent properties such as good fluidity, high spray rate, non corrosive containers and not easy to deteriorate. It is used to extinguish the initial fire design of books, archives, valuable equipment, precision instruments, electrical equipment below 600 volts and oils.

川消二氧化碳灭火器利用所充装的液态二氧化碳喷出灭火的灭火器。由筒体、瓶阀、喷射系统等部件构成。分为：

Chuanxiao carbon dioxide fire extinguisher is a fire extinguisher that uses the filled liquid carbon dioxide to extinguish the fire. It is composed of cylinder, bottle valve, injection system and other components. Divided into:

（1）手提式二氧化碳灭火器。总重量小于或等于28kg，其规格有2kg、3kg、5kg、7kg四种；

(1) Portable carbon dioxide fire extinguisher. The total weight is less than or equal to 28KG, and its specifications include 2kg, 3kg, 5kg and 7kg;

（2）推车式二氧化碳灭火器。总重量大于28kg，其规格有20kg、25kg两种。二氧化碳灭火器适用于扑救各种可燃液体和可燃气体的初起火灾。以及带电设备和精密电子仪器、贵重设备的火灾。但不宜在室外刮大风时使用，在窄小和密闭的空间使用后，要及时通风或人员撤离现场，以防窒息。

(2) Wheeled carbon dioxide fire extinguisher. The total weight is more than 28KG, and its specifications are 20kg and 25kg. Carbon dioxide fire extinguishers are suitable for extinguishing initial fires of various flammable liquids and gases. As well as fires of live equipment, precision electronic instruments and valuable equipment. However, it is not suitable to use it outdoors when there is a strong wind. After using it in a narrow and closed space, ventilation or personnel shall be evacuated from the site in time to prevent suffocation.

市民生活中常接触到的，就是水基型灭火器和干粉灭火器。前者适用于扑救易燃固体或非水溶性液体的初起火灾，还可扑救带电设备火灾。而后者适用范围广，适宜扑灭油类、可燃气体、电器设备等初起火灾。

People often come into contact with water-based fire extinguishers and dry powder fire extinguishers in their daily life. The former is suitable for extinguishing the initial fire of flammable solid or non water soluble liquid, and also for extinguishing the fire of live equipment. The latter has a wide range of applications and is suitable for extinguishing initial fires of oils, combustible gases, electrical equipment, etc.
