When using a
Dry Powder Fire Extinguisher to extinguish flammable or flammable liquid fires, you should aim at the main part of the flame and spray. If the liquid fire being extinguished is flowing and burning, you should aim at the root of the flame from near to far, and spray from left to right until all the flames are extinguished. If a flammable liquid is burning in the container, users should aim at the root of the blaze and rock it to mow, so that the sprayed dry powder flow covers the entire container opening. When the blaze is driven out of the container, the user should continue to spray until the blaze is extinguished. . When extinguishing a flammable liquid fire in a container, care should be taken not to aim the nozzle directly at the liquid surface to prevent the impact of the jet from causing the flammable liquid to splash out and expand the fire, making it difficult to extinguish the fire. If a flammable liquid burns in a metal container for too long and the wall temperature of the container is higher than the self-ignition point of the flammable liquid, it will easily cause re-ignition after extinguishing the fire. If used in conjunction with a
Foam Fire Extinguisher, the fire will be extinguished. Better results.
When a portable dry
Powder Fire Extinguisher is suitable for extinguishing a fire, you can quickly rush to the fire scene with the
Fire Extinguisher in your hand or on your shoulder, and put down the fire extinguisher about 5 meters away from the burning place. If you are outdoors, you should choose to spray in the upwind direction. If the dry powder fire extinguisher used is an external pressure storage type, the operator should hold the spray gun firmly with one hand and lift the opening handle on the gas storage bottle with the other hand. If the gas storage bottle is opened by a hand wheel, turn it counterclockwise, rotate it to the highest position, and then lift the fire extinguisher. When the dry powder is sprayed out, quickly aim at the root of the flame and sweep. If the dry powder fire extinguisher used has a built-in gas storage bottle or a pressure storage type, the operator should first remove the safety pin on the opening handle, then hold the nozzle at the front end of the spray hose, and use the other hand to open the pressure handle Press down and open the fire extinguisher to put out the fire. When using a fire extinguisher with a spray hose or a pressure-storage fire extinguisher, the handle should always be depressed with one hand and cannot be released, otherwise the spray will be interrupted. When using a portable dry powder fire extinguisher to extinguish a solid combustible fire, the spray should be aimed at the most violent burning point and sweep up, down, left and right. If conditions permit, the user can hold the fire extinguisher and spray it while walking around the burning object, so that the dry powder fire extinguishing agent can be sprayed evenly on the surface of the burning object until the flame is completely extinguished.
The barrel of the portable dry powder fire extinguisher is made of high-quality carbon steel and processed with special technology.
