How to use a simple fire extinguisher (1)
Portable: When in use, the handle of the portable fire extinguisher or the fire extinguisher should be carried on the shoulder to the fire scene. At about 5 meters away from the burning place, put down the fire extinguisher, pull out the safety pin first, hold the open handle with one hand, and hold the nozzle at the front end of the spray hose with the other hand. If the fire extinguisher has no spray hose, you can hold the opening pressure handle with one hand, and hold the bottom ring part of the bottom of the fire extinguisher with the other hand. First, aim the nozzle at the burning place, and firmly hold the opening pressure handle to make the fire extinguisher spray. When the extinguished combustible liquid is burning in a flowing state, the user should aim at the root of the flame from near to far and sweep left and right, and move forward quickly until the flame is completely extinguished. If the flammable liquid is burning in the container, it should aim at the flame and shake it left and right to mow. When the flame is driven out of the container, the jet stream will mow along with the flame until the flame is completely extinguished. However, it should be noted that the jet cannot be directly sprayed on the surface of the burning liquid, so as to prevent the impulsive force of the fire extinguishing agent from rushing the combustible liquid out of the container and expanding the fire, making it difficult to extinguish the fire. When extinguishing the initial fire of flammable solid materials, the jet should be directed at the most violent burning place. When the flame is extinguished, measures should be taken in time to prevent it from re-igniting. When using the 1211 fire extinguisher, it cannot be turned upside down or lying on its side, otherwise the fire extinguishing agent will not be sprayed out. In addition, when using it outdoors, you should choose to spray in the upwind direction; when extinguishing a fire in a narrow room, the operator should evacuate quickly after extinguishing the fire, because the 1211 fire extinguishing agent also has certain toxicity to prevent harm to the human body.

Trolley type: when extinguishing a fire, it is generally operated by two people. First, push or pull the fire extinguisher to the fire site, stop at about 10 meters away from the burning place, one person quickly releases the spray hose, holds the spray gun tightly, and aims at the burning place; the other Then quickly open the fire extinguisher valve. The fire extinguishing method is the same as the portable 1211 fire extinguisher.
