How to use different fire equipment

There are more types of fire equipment, and each fire equipment has different uses, of which the fire extinguisher is the most common kind of fire equipment. The fire extinguisher is a light fire extinguishing apparatus that can be moved by human power, it can be used to put out fires by spraying out the filled fire extinguishing agent under its internal pressure. There are many fire extinguishers and their scope of application varies. Only by choosing the right type of fire extinguisher can you effectively fight different types of fires and achieve the desired results. In this article, we will talk about how different fire extinguishers should be used.

Here is the list of contents

The use of a portable 1211 fire extinguisher

The use of a 35kg trolley type dry powder fire extinguisher

The use of foam fire extinguishers

The use of carbon tetrachloride fire extinguisher

The use of carbon dioxide fire extinguisher

The use of a portable 1211 fire extinguisher

Remove the safety pin first, then open the pressure handle with one hand, hold the handle of the horn spray barrel with the other hand, and spray it by holding the pressure handle. Because of the halogenated alkane pollution to the atmosphere, harmful to humans, so the use of 1211 fire extinguishers less and less. Carbon dioxide fire extinguishers are gradually replacing the 1211 fire extinguishers, carbon dioxide fire extinguishers are used in the same way as the 1211 fire extinguishers. But in the use of carbon dioxide must be careful not to hold the hand nozzle or touch the mouth to prevent frostbite.

The use of a 35kg trolley type dry powder fire extinguisher

Two people operate, one person removes the gun, unfolds the hose, and then holds the trigger by hand; the other person pulls out the safety pin of the opening mechanism and quickly opens the fire extinguisher opening mechanism.  

The use of foam fire extinguishers

The extinguishing liquid of foam fire extinguisher is composed of aluminum sulfate, sodium bicarbonate, and licorice essence. When extinguishing the fire, the foam extinguisher is inverted and the foam can be sprayed out to cover the fire and achieve the purpose of extinguishing the fire. Foam extinguishers are suitable for extinguishing fires in barrels of oil, pipelines, and floors, but not for fires in electrical equipment and precision metal products.

The use of carbon tetrachloride fire extinguisher

Carbon tetrachloride is colorless, transparent, non-conductive, and denser than air gas after vaporization. To extinguish a fire, turn the body upside down with the nozzle down and turn the hand valve to spray the flame to extinguish it. Carbon tetrachloride fire extinguishers are suitable for extinguishing fires in electrical equipment and valuable instruments and equipment. Carbon tetrachloride is highly toxic, so users should stand upwind. Indoors, ventilate promptly after extinguishing the fire.

The use of carbon dioxide fire extinguisher

Carbon dioxide is a non-conductive gas, denser than air, and is liquid under high pressure in the cylinder. When extinguishing the fire, you only need to toggle the switch, carbon dioxide is sprayed on the fire in the state of airflow, isolating the air, so that the flame is extinguished. A carbon dioxide fire extinguisher is suitable for small area fires in places such as precision instruments, electrical equipment, and oil laboratories. When carbon dioxide changes from liquid to a gaseous state, it absorbs a lot of heat and the temperature is extremely low (can reach -80℃), so avoid frostbite. Meanwhile, although carbon dioxide is non-toxic, it has an asphyxiating effect and should be avoided by inhalation as much as possible.
