We can extinguish fire by :-a)removing non combustible substances from...
Removing non combustible substances from surroundings:
- Combustion requires fuel, oxygen, and heat. By removing non combustible substances from the surroundings, we ensure that there is less fuel available for the fire to feed on.
- This can help in preventing the fire from spreading and eventually extinguishing it.
Cutting the supply of oxygen:
- Oxygen is crucial for combustion to occur. By cutting off the supply of oxygen, we can effectively suffocate the fire and prevent it from continuing to burn.
- Methods such as using fire extinguishers, covering the fire with a blanket, or closing off vents can help in cutting off the oxygen supply.
Lowering temperature below ignition temperature:
- Every substance has an ignition temperature, which is the minimum temperature required for it to ignite. By lowering the temperature below this threshold, we can prevent the fire from sustaining itself.
- This can be achieved by using water, foam, or other cooling agents to bring down the temperature of the burning material.
Both cutting the supply of oxygen and lowering temperature below ignition temperature:
- By combining both these methods, we can effectively extinguish the fire. Cutting off the oxygen supply prevents the fire from getting the necessary element to burn, while lowering the temperature helps in reducing the heat energy required for combustion.
- Firefighters often use a combination of tactics to tackle fires, ensuring that both the oxygen supply is cut off and the temperature is reduced to successfully extinguish the flames.
In conclusion, by removing non combustible substances, cutting the oxygen supply, and lowering the temperature below ignition levels, we can effectively extinguish fires and prevent them from causing further damage.
