How to use a dry powder fire extinguisher

1. In case of emergency, the dry powder fire extinguisher cannot be used directly after being brought back. It should be held in your hand and shaken up and down and left and right several times, at least three times, to loosen the dry powder inside, and then you can pull the safety pin on the dry powder fire extinguisher.

2. After the safety pin of the dry powder fire extinguisher is pulled out, hold its leather coil with your hand and aim the tube mouth at the fire point. Then you can use your other hand to press the pressure bar on the dry powder fire extinguisher to spray the dry powder onto the fire point. As long as you follow these steps, you can extinguish the fire quickly and make the dry powder fire extinguisher play the best role.

The correct way to use dry powder fire extinguisher

1. When using a dry powder fire extinguisher, you must understand its structure. In addition to the tank body, the dry powder fire extinguisher also has a pan, a pressure plate, and a lead seal on it. Only after removing the lead seal can the dry powder fire extinguisher be used normally.

2. Before using a dry powder fire extinguisher, you should shake the tank a few times to loosen the dry powder inside, and then remove the lead seal on it. After removing it, hold the nozzle with your left hand, and then stand upwind, 4 to 5 meters away from the fire point, and then press the pressure handle hard with your right hand to aim the nozzle at the fire point, and then swing it left and right to let the dry powder climb on the fire point as much as possible, so that the fire can be extinguished quickly.

3. Use a dry powder fire extinguisher to extinguish the fire at the root of the flame. After the flame is extinguished, use cold water to remove the smoke. Only in this way can you prevent the fire from rekindling and completely extinguish it.
