Explanation of the use of fire extinguishers and fire fighting equipment

How to use a fire extinguisher?

1. Dry powder fire extinguisher.

Dry chemical fire extinguishers are easy to use and have a long validity period. It is suitable for extinguishing all kinds of flammable, combustible liquid and flammable and combustible gas fires, as well as electrical equipment fires.

How to use: Drag the pressure handle with your right hand, drag the bottom of the fire extinguisher with your left hand, gently remove the fire extinguisher, remove the lead seal, pull out the safety pin, then hold the nozzle with your left hand, hold the pressure handle with your right hand, stand two meters away from the flame, press down the pressure handle with your right hand, swing from side to side with the nozzle in your left hand, and spray dry powder to cover the entire burning area.

2. Foam fire extinguisher.

Foam fire extinguishers are suitable for extinguishing all kinds of oil fires and solid combustible fires such as wood, fiber, and rubber.

How to use: When using a foam fire extinguisher, you should pay attention to the person standing upwind and try to get as close to the fire source as possible, because its spray distance is only 2-3 meters, spray from the side where the fire is most dangerous, and then move gradually, being careful not to leave sparks. Hold the wooden handle of the nozzle in your hand to avoid frostbite.

Because the amount of carbon dioxide in the air is too much, it is also bad for the human body, so in the occasion of poor air flow, it should be ventilated immediately after spraying.

3. Carbon dioxide fire extinguisher.

The carbon dioxide fire extinguisher has high fire extinguishing performance, low toxicity, low corrosiveness, and does not leave traces after extinguishing the fire, making it easy to use. It is suitable for all kinds of flammable, combustible liquid and combustible gas fires, and can also extinguish instruments, books and archives and low-voltage electrical equipment, as well as electrical appliances below 600 volts.

Proper use of fire extinguishers to extinguish fires:1. Pick it up with your hands first, shake it a few times, and shake the dry powder inside loosely.

2. Pull the ring outward by hand to pull the safety pin apart.

3. Hold the pressure handle with one hand and grasp the nozzle with the other hand, and place the fire extinguisher upright on the ground.

4. Press down hard to dry the powder and it will spray out, aim at the root of the fire, and stand upwind, about three meters away from the fire point.

Precautions for using fire extinguishers:1. Before using, remember to understand each type first, because the scope of application is different depending on the type. In this case, only dry powder fire extinguishers can be used, and foam fire extinguishers must not be used, which will only increase the fire, and will also pose a great threat to the personal safety of the fire extinguisher, and there may be electric shock.

2. If it is a large public place, it is necessary to place a few more fire extinguishers, to meet the corresponding requirements, and to put it in an obvious place, so that after the fire, people can find it in the first time, and the fire extinguisher needs to be checked regularly to see whether its bottle pressure is normal.

Education Introduction] Extinguishing fires with water. Wood, paper, etc. can be extinguished with water. Sprinkle water directly on the combustible material to extinguish the flames.

Fire extinguishers are commonly used.

1. Dry powder fire extinguisher. This type of fire extinguisher gets its name from the fact that the cartridge is filled with dry chemical extinguishing agent. It is mainly suitable for fighting liquid fires, live equipment fires, especially for gas fires, and is not suitable for fighting precision instrument fires;

2. Foam fire extinguisher. The fire extinguisher that uses spray foam to extinguish the fire is mainly suitable for extinguishing oil fires, such as gasoline, kerosene, vegetable oil and other initial disasters; It can also be used to extinguish general solid material fires, such as wood, cotton, hemp, bamboo and other fires and fires caused by aircraft and automobile accidents; It is not suitable for extinguishing live equipment fires and gas fires;

3. Carbon dioxide fire extinguisher. Vaporized carbon dioxide gas is used to extinguish fires. It is suitable for extinguishing fires of books and archives, precision instruments and valuable equipment. Because it is non-conductive, it can extinguish live equipment fires.

How to use a fire extinguisher - how to use a fire extinguisher in common ways.

Fire extinguishers can be seen everywhere in our daily life, there are many types of fire extinguishers, and the use of various fire extinguishers is different, so we should pay attention to which fire extinguisher to use and how to use it when using the stall. Below, I will share with you the operation and use of commonly used fire extinguishers, I hope it will be helpful to you!

Fire is one of the most common and common disasters, and its occurrence often causes countless irreparable tragedies and poses a huge threat to the life and property safety of the public. Therefore, we should not only be cautious when using fire to avoid fire, but also learn a series of escape methods in a fire, and master how to extinguish fire. Next, we will lead you to learn how to use fire extinguishing equipment and related precautions.

Dry chemical fire extinguishers

There are two types of dry chemical fire extinguishers: BC type and ABC, the former can be used to extinguish the fire of flammable liquids and electrical equipment, and the latter can also be used for the fire of solid flammable materials. How to use: You can use the hand or shoulder resistance to hold the fire extinguisher, unplug the safety pin on the fire extinguisher, aim the sprinkler pipe of the fire extinguisher at the fire source (when used outdoors, it should be in the upwind direction of the downwind), and then press down the opening handle to open the fire extinguisher to extinguish the fire.

CO2 fire extinguisher

In terms of design, there are two types of carbon dioxide fire extinguishers, one is with a spray hose, which is similar to the use of dry fire extinguishers. The other does not have a sprinkler pipe, and we should break the horn barrel up about 80 degrees to open the fire extinguisher to extinguish the fire. Carbon dioxide fire extinguishers can be used to extinguish fires in flammable liquids as well as electrical equipment.

When using, you should pay attention not to directly touch the metal tube or horn barrel with your hands to avoid frostbite, and at the same time, you should leave in time after use to prevent hypoxic suffocation.

Foam fire extinguisher

Hold the upper ring of the fire extinguisher with one hand and pick up the fire extinguisher, taking care not to tilt the foam fire extinguisher too much, let alone turn it upside down. At a distance of about 10 from the point of fire, turn the fire extinguisher upside down, hold the bottom ring of the fire extinguisher with the other hand, and spray foam from near to far to extinguish the fire. Foam fire extinguishers are usually used for fires of combustible solids and liquids, and if an electrical appliance is on fire, it can only be used after the power is cut off.

In general, no matter what kind of fire extinguisher is used to extinguish a fire, there are a few things we must pay attention to:1When extinguishing the fire, aim at the bottom of the flame in order to quickly and thoroughly cut off the source of the fire; 2.

Generally, we have to stand upwind and spray downwind to avoid the projectile in the fire extinguisher being blown to ourselves by the wind; 3.If it is an oil surface**, we cannot spray directly into the oil surface, so as not to burn ourselves by splashing oil droplets; 4.When electrical equipment is on fire, it is best to cut off the power supply in time to prevent electric shock.

The preservation and utilization of fire is a great progress in the history of human civilization, but while using fire as a tool, we should always be vigilant about the safety of fire. I hope that you will have a good grasp of the knowledge mentioned above, take precautions in your daily life, and respond calmly when facing fires.
