Today, CO2 fire extinguisher manufacturers take you to know about our CO2 fire extinguisher. The emergence of such fire extinguishers has a very long history.

This fire extinguisher was invented more than 100 years ago. It was originally a portable compressed gas container. Until now, it has developed into a technology that compresses liquid carbon dioxide in small steel cylinders by pressurization. Spray it out to cool down and isolate the air.

The working principle of this fire extinguisher is that according to the nature that carbon dioxide can neither burn nor support combustion, various carbon dioxide fire extinguishers have been developed, including foam fire extinguishers, dry powder fire extinguishers and liquid carbon dioxide fire extinguishers. With the continuous development of the times and the advancement of science and technology, more and more fire extinguishers for special fire causes have been developed.

At present, when this carbon dioxide fire extinguisher is in use, it is necessary to pay attention to the fire extinguisher to the fire location first, lower the fire extinguisher, pull out the safety pin, hold the handle of the root of the trumpet with one hand, and the pressure handle of the on-off valve . For a carbon dioxide fire extinguisher without a spray hose, the horn should be turned up 70-90 degrees. When in use, do not directly grasp the outer wall of the horn or the metal connection pipe to prevent frostbite. When using a carbon dioxide fire extinguisher, if it is used outdoors, it should be sprayed in the upwind direction; if it is used in a narrow space indoors, the operator should leave quickly after the fire to prevent suffocation.

You can carry the lifting ring on the upper part of the barrel to quickly go to the fire. At this time, care should be taken not to make the fire extinguisher excessively tilted, nor to hold it horizontally or upside down, so as to prevent the two agents from mixing and spraying in advance. When the distance from the ignition point is about 10 meters, the cylinder can be turned upside down. Hold the lifting ring firmly with one hand and hold the bottom circle of the cylinder with the other hand to align the jet with the burning object.

We need a clear understanding of the use of fire extinguishers in order to control the fire in time when a fire occurs.
