在面对火灾的时候，我们要懂得判断火灾引起的原因以及怎么处理，这样才能更好的选择相对应的灭火器来进行灭火。那么，你知道泡沫灭火器主要用于扑灭什么火灾吗？

When facing a fire, we should know how to judge the cause of the fire and how to deal with it, so that we can better choose the corresponding fire extinguisher to put out the fire. Then, do you know what kind of fires foam extinguishers are mainly used to extinguish?

泡沫灭火器主要用来扑灭A类火灾，如木材、棉布等固体物质燃烧引起的失火；适宜扑救B类火灾，如汽油、柴油等液体火灾；不能扑救水溶性可燃、易燃液体的火灾（如：醇、酯、醚、酮等物质）和E类（带电）火灾。

Foam fire extinguishers are mainly used to extinguish class a fires, such as fires caused by the burning of solid substances such as wood and cotton cloth; Suitable for extinguishing class B fires, such as gasoline, diesel and other liquid fires; The fire of water-soluble flammable and combustible liquids (such as alcohols, esters, ethers, ketones and other substances) and class E (charged) fires cannot be extinguished.

此类灭火器是通过筒体内酸性溶液与碱性溶液混合发生化学反应，将生成的泡沫压出喷嘴，喷射出去进行灭火的。它除了用于扑救一般固体物质火灾外，还能扑救油类等可燃液体火灾，但不能扑救带电设备和醇、酮、酯、醚等有机溶剂发生的火灾。

This kind of fire extinguisher is mixed with acidic solution and alkaline solution in the cylinder to produce chemical reaction, and the generated foam is pressed out of the nozzle and sprayed out to extinguish the fire. It is not only used to put out fires of general solid substances, but also can put out fires of flammable liquids such as oils, but it cannot put out fires of live equipment and organic solvents such as alcohols, ketones, esters, ethers, etc.

川消泡沫灭火器的原理十分简单，就是在使用泡沫灭火器的时候，灭火器能够喷射出大量的二氧化碳。泡沫灭火器的内部装有两个容器，一个容器盛有硫酸铝，另一个容器装有碳酸氢钠溶液。这两个容器是分别独立的，因此这两种化学物品互不接触，不会发生任何化学反应。

The principle of Chuanxiao foam fire extinguisher is very simple, that is, when using foam fire extinguisher, the fire extinguisher can eject a large amount of carbon dioxide. There are two containers inside the foam extinguisher, one containing aluminum sulfate and the other containing sodium bicarbonate solution. The two containers are independent, so the two chemicals do not contact each other and no chemical reaction will occur.

当要使用泡沫灭火器时，就把灭火器倒立，使得两种溶液相互接触并且混合在一起，发生化学反应，产生大量的二氧化碳。不仅如此，在灭火器里还有一些发泡剂用来产生泡沫。在使用泡沫灭火器的时候打开开关，泡沫会从开口处喷出，覆盖在物品上，隔绝氧气并且降低燃烧物品的温度，因而达到灭火的目的。而且喷出的泡沫里还含有大量的水分，不会产生任何污染物。

When you want to use a foam fire extinguisher, stand the extinguisher upside down, so that the two solutions contact each other and mix together to produce a chemical reaction and produce a large amount of carbon dioxide. Not only that, there are also some foaming agents in fire extinguishers to produce foam. When using the foam fire extinguisher, turn on the switch, and the foam will be sprayed from the opening to cover the items, isolate oxygen and reduce the temperature of the burning items, so as to achieve the purpose of extinguishing the fire. And the foam also contains a lot of water, which will not produce any pollutants.

由于泡沫灭火器喷出的泡沫中含有大量水分，它不如二氧化碳液体灭火器，灭火后不污染物质，不留痕迹。可用来扑灭木材，棉布等燃烧引起的失火，还能扑救油类等可燃液体火灾。

Because the foam emitted by the foam extinguisher contains a lot of water, it is not as good as the carbon dioxide liquid extinguisher, which does not pollute substances and leave no traces after extinguishing. It can be used to put out fires caused by the burning of wood, cotton cloth, etc., and also to put out fires caused by flammable liquids such as oil.
