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.
