How does a file extinguisher work?
Ans: All of you might have seen fire extinguisher cylinders. How it works and how it is operated, we will discuss here.
At the top of the cylinder, there is a small cylindrical container filled with compressed gas. The release valve acts as a locking mechanism and prevents this gas from avoiding. When you pull the safety pin and pull the liver, the liver pushes a stick which opens the path of the nozzle to suppress the valve. Compressed gas has been released, low pressure is used on fire extinguishing material, and exits the nozzle under tremendous strength.
CO2 firefighters are commonly used. Carbon dioxide is a non-flammable gas. As we know that CO2 is heavier than oxygen and is very cold, it removes oxygen from the surrounding area or cools the fuel.
How to operate these- See the figure below for this. The keyword here is PASS. Each letter of this word is explained in the figure.
