The commonly used fire extinguisher shared with you the scope of the common fire extinguisher


Scope of application of fire extinguishers

Carbon dioxide fire extinguisher


Carbon dioxide fire extinguishers, the main internal installation is

Liquid carbon dioxide


, Consisting of bottle valves, jet systems, etc.

Carbon dioxide fire extinguishers are mainly applicable

, Specifically, it can be used for saving

The initial fires of all kinds of flammable liquids, the initial fire of combustible gas. At the same time, for books, archives, and power -based equipment (below 600V), precise electronic instruments, valuable equipment fire can also be used by carbon dioxide, and the extinguishing effect of refrigeration. Use in a narrow and closed space. Remember to evacuate personnel after use and ventilate in time.

Dry powder fire extinguisher

The inside of the dry powder fire extinguisher is equipped with a dry powder fire extinguishing agent such as phosphoric acid salt, and the internal carbon dioxide gas or nitrogen gas is used as power to spray the dry powder to extinguish the fire

These subtle dry powder have easy flowing, dry adsorption, and easy to spray characteristics.

The use range of dry powder fire extinguishers is relatively wide,

The general fire is more applicable, and it can also be used to extinguish the fire caused by combustion such as oil, organic solvents, and combustible gas. It can also be saved with cheaper electrical equipment in the early stages of fire.

Foam fire extinguisher

Inside the foam fire extinguisher, the main is the mixed solution of sodium bicarbonate and the foaming agent. In addition, there is a glass inner tendon, which is equipped with aluminum sulfate aqueous solution. When used, the two liquid was mixed. The bubble of carbon dioxide gas in it


The volume expands sharply, and the spray distance is relatively far. On the one hand, it can reduce the temperature, and on the other hand, it also plays a role in isolation of air fire extinguishing.

Scope of application of foam fire extinguishers:

Mainly used for category A fire and Class B fire.

For example, for cotton cloth, wood, dry plant, fire caused by these items,

For the fire caused by the flammable liquid that is insoluble in water, the foam fire extinguisher can also be competent, but for liquid fires like ethanol like water, the foam fire extinguisher is not applicable.
