Pouring water on it . This is because water is an insulator of fire. This is done by an device called fire extinguisher. He can also pour sand.
The second way is to cut the supply of oxygen. Due to cutting the supply of the oxygen, combustion will not be possible.
Step 1: Pull the pin. Most fire extinguishers have a unique safety seal. Our safety seal is the yellow tag which also acts as the locking mechanism to prevent any accidental discharge.
Step 2: Aim at the base of the fire. Upon unlocking the safety pin, aim the nozzle at approximately 1.5 meters to the base of the fire. The biggest mistake people make is not aiming at the base of the fire. It is important, the goal is the kill the source of the fire - in this case, it's the base of the fire.
Step 3: Squeeze the lever. Once you’ve got your aim, gently squeeze the lever to release the extinguishing agent. Be wary when squeezing it as there’s a limited amount of extinguishing agents so control it wisely.
Step 4: Sweep from side to side. Upon squeezing, while still focusing at the base of the fire, adjust your position to sweep the fire extinguisher left and right to cover as much area as possible. Do take note of the wind direction if you're outdoors as that will determine where the fire will spread. Always stand against the wind direction so you are away from the direction of the fire.
