How to use a dry powder fire extinguisher

1. Before using a dry powder fire extinguisher, be sure to check whether the pressure of the dry powder fire extinguisher is within the normal range. There is a special pressure gauge on all dry powder fire extinguishers. If the pointer is in the yellow area of ​​the pressure gauge, it means that the pressure is sufficient. If it is in the green area, it means that the pressure is normal. If it is in the red area, it means that the dry powder fire extinguisher is under-pressurized and cannot be used normally. It must be sent to the relevant department for stamping before it can be used again.

2. Before using a dry powder fire extinguisher, do not rush to use it. You should shake it vigorously for a few times first. Only in this way can the dry powder in the fire extinguisher be loosened and sprayed out as soon as possible when used. Put the dry powder fire extinguisher away, hold the pull ring with your hand, and pull out the lead seal on it. You must use force, otherwise it will be difficult to pull it out.

3. After removing the safety of the fire extinguisher, hold the pressure handle with one hand and hold the nozzle with the other hand, and grasp the direction. Place the fire extinguisher in the correct position and place it vertically, then press the pressure handle hard, and the dry powder inside will spray out from the nozzle.

4. When using a dry powder fire extinguisher to put out a fire, the dry powder should be sprayed at the root of the flame, and you should stand upwind about three meters away from the flame until the flame is completely extinguished before you stop spraying. If the fire is large and the dry powder fire extinguisher in your hand is small, you need several people to spray the dry powder at the fire point on the dry powder fire extinguisher at the same time, so that the fire can be extinguished quickly. In addition, when using a dry powder fire extinguisher to put out a fire, you must stand upwind and keep the dry powder away from your mouth and nose to prevent yourself from absorbing the dry powder during the spraying process.
