1. Types of fire extinguishers and types of fires that can be extinguished


Dry powder fire extinguisher (ABC fire extinguisher): The most common fire extinguisher on the market today. Types of fires that can be extinguished: ABCEF, dry powder fire extinguishers can be used for most home fires (the effect of Class F fires is not very good)

Advantages: cheap, easy to operate, adaptable to various extreme weather (-20℃~55℃)


Disadvantages: It is easy to affect the line of sight during use, it will pollute the furniture, it is inconvenient to clean up, and it cannot prevent re-ignition


Water-based fire extinguisher: It is an environmentally friendly fire extinguisher, and the type of fire that can be extinguished: ABEF.

Advantages: easy to operate, less pollution, fast fire extinguishing, flame retardant, can spray on people (some cannot)


Disadvantages: The service life is relatively short, only about 6 years, the price is slightly expensive, and the temperature requirements are higher


In domestic use, remember that it cannot be used to extinguish a gas fire. If the kitchen uses natural gas, it is best not to put a water-based fire extinguisher.


There are two types of water-based fire extinguishers that can extinguish electric fires and those that cannot extinguish electric fires. When buying a family, it is best to buy a water-based fire extinguisher that can extinguish electric fires.


Carbon dioxide fire extinguisher: It mainly extinguishes the fire by reducing the oxygen in the air and cooling. It can extinguish: BCE fire.


Advantages: no pollution, no damage to precision equipment


Disadvantages: Improper operation, easy to frostbite, suffocation, carbon dioxide poisoning, very expensive


Aerosol Fire Extinguisher: Can extinguish ABCEF fires (partly BCEF)

Advantages: light and easy to carry, non-toxic and non-destructive, no pressure, explosion-proof, no maintenance, easy to operate, strong fire extinguishing power, and can adapt to the temperature of -30 ℃ ~ 70 ℃.


Disadvantages: expensive, generally used in small places


Pure aerosol has no residue at all and cannot extinguish Class A fires; aerosol fire extinguishers with dry powder particles will have a small amount of powder, which can extinguish Class A fires


Heptafluoropropane Fire Extinguisher: Can extinguish ABCE fires

Advantages: colorless, odorless, non-conductive, no secondary pollution, in line with environmental protection requirements, high fire extinguishing efficiency, no pollution to equipment, good electrical insulation performance


Cons: Really expensive!


The biggest advantage of heptafluoropropane fire extinguisher is its non-conductive properties. For precision electrical equipment, it is ideal to use heptafluoropropane as a fire extinguisher, because it does not contain particulate oil after it is released, it will not damage the environment, and when it reaches a certain concentration, there are still The effect of suppressing explosions.


Generally speaking, families seldom buy this fire extinguisher because it is really expensive, but its efficient fire extinguishing ability and the advantages of clean fire extinguishing without cleaning, many families choose to buy it, especially in the home with valuables room, library, precision instruments while waiting for items.
