(Photo by Xinhua News Agency reporter Tang Yi) What does “fighting fire with fire” mean? Forest fire rescue personnel are here to popularize science👇 It looks like the fire is getting bigger? But it is actually putting out the fire! Firefighter: That's "reverse ignition" Participate in organizational guidance Chongqing Beibei District "fight fire with fire" tactics implemented Wang Lei, Director of the Operations Training Department of Yunnan Provincial Forest Fire Brigade Introducing to CCTV reporters Forest firefighters are fighting a forest fire According to the on-site situation Sometimes a special fire extinguishing method is used It is called "fighting fire with fire" △Commanders and fighters of Yunnan Provincial Forest Fire Brigade ignited the fire in accordance with operating procedures. Many netizens asked: 🔥VS🔥=🔥🔥 Wang Lei introduced In fact, the principle of using fire to extinguish fire is mainly Reverse ignition, fighting fire with fire In the brief moment when the two wildfires met Isolate the oxygen and combustibles needed for wildfires to burn Causes fire to extinguish As a fire spreads, it creates updrafts In this way, airflow from other directions will flow in to supplement Form a wind In the opposite direction of the fire (That is, the front where the fire spread) Artificially lit fire The two fires will run in one direction. Final Encounter Because of the two fires around There is no more material to burn. At the same time, the oxygen in the middle of the fire is used up. The fire went out Wang Lei introduced that this method is generally used in Use when wind force and direction are relatively stable If the wind is strong, the effect will be counterproductive. Attention should be paid to the distance between the ignition point and the fire zone. Too far is like setting fire, too close is like helping the burning Also pay special attention to the wind direction, all of which requires experience The summary is as follows 👇 Areas where fires are burning When the temperature is high, the airflow rises, creating low pressure. The surrounding airflow is concentrated towards the fire area. Ignite at the proper distance The fire will spread along the airflow to the fire area. Soon a circle formed in front of the fire. No burning zone This stopped the fire from spreading.
