Types of fire extinguishers commonly used in hotels

The types of fire extinguishers commonly used in hotels include foam fire extinguishers, dry powder fire extinguishers, carbon dioxide fire extinguishers, water fire extinguishers, haloalkane fire extinguishers, clean gas fire extinguishers, etc.

1. Foam fire extinguisher

The foam fire extinguisher is filled with sodium bicarbonate and aluminum sulfate water respectively. When using the foam fire extinguisher, turn it upside down so that the two solvents in the fire extinguisher are fully combined. Create carbon dioxide bubbles. The carbon dioxide foam sprayed by the fire extinguisher has a small specific gravity and can adhere to combustible materials, thereby isolating the air and extinguishing the fire. This type of fire extinguisher can extinguish Class A and B fires.

2. Dry powder fire extinguisher

Dry powder fire extinguisher refers to a fire extinguisher bottle filled with dry powder fire extinguishing agents such as ammonium phosphate and sodium chloride. These fire extinguishing agents and fuels will produce chemical inhibition and other effects, thereby interrupting combustion. Moreover, dry powder fire extinguishing agents will form a covering layer on the surface of combustible materials to isolate oxygen. ABC dry powder fire extinguishers can generally extinguish Class A, B, C, and E fires. Bc dry powder fire extinguisher can extinguish B, C and E fires.

3. Carbon dioxide fire extinguisher

This type of fire extinguisher bottle is generally filled with liquid carbon dioxide. When a carbon dioxide fire extinguisher is used to extinguish a fire, the liquid carbon dioxide will vaporize immediately, absorb heat from the surroundings, and Cooling effect. Carbon dioxide gas will be distributed on the surface of combustible materials and play a fire-extinguishing effect by reducing the oxygen concentration. It can be used to extinguish Class B, Class C, and Class E fires.

4. Clean water fire extinguishers

Clear water fire extinguishers are filled with clean water and added with additives such as antifreeze. This type of fire extinguisher extinguishes fires through the principles of cooling and suffocation. Clean water can absorb sensible heat and latent heat and have a significant cooling effect. Clean water forms steam when heated, which can reduce the oxygen solubility in the fuel area and so on. Water fire extinguishers are mainly used to extinguish Class A fires.

5. Halonated alkyl fire extinguishers

This type of fire extinguisher is filled with haloalkane fire extinguishing agents, such as difluorodibromomethane, trifluorobromomethane, etc. This type of fire extinguisher can extinguish flammable gas, liquid fires, solid fires, electrical fires, and thermoplastic fires. At present, 1211 haloalkyl fire extinguisher and 1301 haloalkyl fire extinguisher have been eliminated.

6. Clean gas fire extinguisher

Clean gas fire extinguisher is an inert gas fire extinguishing system, including heptafluoropropane gas fire extinguishing system, IG-541 fire extinguishing system, etc. The inert gas filled in this type of fire extinguisher is a non-toxic, odorless, inert, non-conductive compressed gas. It has high fire extinguishing efficiency and strong environmental protection, and can be used to extinguish Class A, B, C, and E fires.
