There are four main types currently on the market? 

 

The fire extinguishing agent stored in the tank is carbon dioxide gas. It will not leave traces on the scene after the fire is extinguished. Therefore, it is widely used for fire extinguishing in archives, computer rooms and other places. It can also be used to extinguish and rescue valuable instruments and equipment, as well as extinguish initial fires caused by electrical equipment below 600 volts. When using, pressurize first and then start spraying. 

 

The fire extinguishing agent stored in the tank is dry powder. It needs to be blown with nitrogen when used. It can be used to extinguish fires caused by paint, petroleum products, organic solvents, etc. It can also be used to extinguish electrical fires, liquid fires, gas fires, solid fires, etc. 

 

The fire extinguishing agent stored in the tank is a chemical foam mixed with aluminum sulfate and sodium bicarbonate. When foam is sprayed on the surface of the burning material, air cannot enter the inside of the burning material. When using, the fire extinguisher should be turned upside down to allow the two components to mix thoroughly to form foam. This kind of fire extinguisher can be widely used to extinguish liquid fires, but it is not suitable for extinguishing fires caused by electrical equipment, nor is it suitable for extinguishing fires caused by flammable liquids. 

 

The fire extinguishing agent stored in the tank is water, which uses cold cutting and suffocation to extinguish fires. However, due to the poor fire extinguishing effect, wetting agents, Kang Dongji, etc. are often added during use to extinguish fires caused by solid stains.

 

1. When spraying, you must keep a distance of about 1.5-2 meters from the fire source. 

2. It should be noted that spraying must be aimed at the fire source to effectively extinguish the fire. 

3. Be sure to stand upwind of the fire source when spraying.

 

The five steps are: observe, mention, pull, aim, and release pressure.

Refers to whether the fire extinguisher is still effective and whether the pressure gauge pointer is in the green area. 

Refers to the hands that pick up the fire extinguisher.
