What are the types of fire extinguishers?

1. Dry powder fire extinguisher: The dry powder fire extinguisher is filled with dry powder fire extinguishing agent. Dry powder fire extinguishing agent is a dry and easy-to-flow fine powder used for fire extinguishing, which is composed of inorganic salts with fire extinguishing effect and a small amount of additives that are dried, crushed and mixed into fine solid powder.

Compressed carbon dioxide is used to blow out a dry powder (mainly containing sodium bicarbonate) to extinguish the fire.

2. Foam fire extinguisher: There are two containers in the foam fire extinguisher, which contain two liquids, which are aluminum sulfate and sodium bicarbonate solutions, and the two solutions do not contact each other and do not have any chemical reaction. When a foam fire extinguisher is needed, turn the fire extinguisher upside down and mix the two solutions together, which will produce a large amount of carbon dioxide gas.

3. Carbon dioxide fire extinguisher: the liquid carbon dioxide is stored in the bottle of the fire extinguisher, and when working, when the pressure handle of the bottle valve is pressed, the internal carbon dioxide fire extinguishing agent will be sprayed out from the siphon through the bottle valve to the nozzle, so that the concentration of oxygen in the combustion area will drop rapidly, and the flame will be suffocated and extinguished when the carbon dioxide reaches a sufficient concentration, and at the same time, because the liquid carbon dioxide will be rapidly vaporized, it will absorb a large amount of heat in a short time, so it will play a certain cooling role in the combustibles, and also help to extinguish the fire.
