灭火器使用不当的话会存在爆炸危险，所以在使用的时候应正确使用。下面川消小编就来从几个方面为您介绍该灭火器的用法吧。

Improper use of fire extinguishers may cause explosion hazard, so they should be used correctly. Let's introduce the use of the fire extinguisher from several aspects.

灭火器的使用应避免以下三种情况：

The use of fire extinguishers should avoid the following three situations:

一：将过期灭火器放在潮湿环境中，导致灭火器瓶体表面腐蚀，受不起压力，从而导致爆炸；

1： Put the expired fire extinguisher in a humid environment, which will cause the surface of the fire extinguisher to corrode and not bear pressure, thus causing explosion;

二：将灭火器放置在高温环境里，导致受热膨胀爆炸；

2： Place the fire extinguisher in a high temperature environment, resulting in thermal expansion and explosion;

三：灭火器属于小型压力容器，因猛烈撞击变形后可能发生爆炸。

3： The fire extinguisher is a small pressure vessel, which may explode after being deformed due to violent impact.

加强灭火器的维护保养应注意三个方面：

The maintenance of fire extinguishers should be strengthened in three aspects:

一：对灭火器必须进行定期检查、换药、试压。凡机壳损坏，受压能力不足的灭火器坚决淘汰；

1： Fire extinguishers must be regularly inspected, changed and pressure tested. Extinguishers with damaged casing and insufficient pressure capacity shall be eliminated;

二：灭火器换药时，要将筒内锈渣清洗干净，药液要用纱布过滤。平时灭火器喷嘴可套上纸套，以防灰尘等侵入堵塞喷嘴。灭火器药渡喷完后，不要马上找开机盖，防止剩余气压伤人。

2： When the fire extinguisher is changed, the rust residue in the cylinder shall be cleaned, and the solution shall be filtered with gauze. At ordinary times, the fire extinguisher nozzle can be covered with a paper sleeve to prevent dust and other intrusion from blocking the nozzle. After the fire extinguisher is sprayed, do not look for the cover immediately to prevent the residual air pressure from hurting people.

三：灭火器喷不出药剂，可用铁丝疏通喷嘴，千万不要往火里抛，否则，机壳在高温下易变形，药液受势膨胀，使灭火器内压力大大增加，也会引起消防事故。

3： If the fire extinguisher can not spray chemicals, the nozzle can be dredged with iron wire. Never throw it into the fire. Otherwise, the casing is easy to deform under high temperature, and the liquid medicine is subject to potential expansion, which will greatly increase the pressure in the fire extinguisher and also cause fire accidents.

此外要注意，过期的灭火器不能卖给废品回收站，因为罐内会残存惰性气体，容易发生爆炸。为上，使用要正确，更多消防设备的使用就来我们网站http://www.cx-fire.com咨询吧！

In addition, it should be noted that expired fire extinguishers cannot be sold to the waste recycling station because inert gas will remain in the tank, which is prone to explosion. Safety first, use correctly, and use more fire-fighting equipment on our website http://www.cx-fire.com Ask!
