Can a fire extinguisher put out any fire?

Can a fire extinguisher put out any fire?

Class A extinguishers can put out fires from “ordinary combustibles” such as wood, plastic or paper. Class B can put out burning liquids such as gasoline or grease. Class C can put out electrical fires. Extinguishers marked A, B and C can put out all types.

How does fire extinguisher put out fire?

Most fire extinguishers work by separating the fuel from the oxygen. The oxygen comes from the air. It is the same oxygen we breathe. Since the oxygen has to be in contact with the fuel, if you can coat the fuel with something that keeps the oxygen away, the fire will go out.

What frequency puts out fire?

The acoustic fire extinguisher puts out flames using low frequency bass (30 to 60Hz) without relying on water or chemicals.

Why does co2 put out fire?

Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well.

Which fire extinguisher can put out most fires?

multipurpose dry chemical
The most widely used type of fire extinguisher is the multipurpose dry chemical that is effective on Class A, B, and C fires. This agent also works by creating a barrier between the oxygen element and the fuel element on Class A fires. Ordinary dry chemical is for Class B and C fires only.

Can frequency put out fire?

Since sound waves can move oxygen and fire through pressure from their vibrations, this specific frequency of sound wave works to separate the flame molecules from the surrounding oxygen, effectively starving the fire and snuffing out the flame.

Can we put out fire with sound?

Because sound is a pressure wave that oscillates between regions of high and low pressure, the oscillation can be exploited to create a vacuum that separates air molecules from the sounds of the flame, putting out the fire. Rather, low-frequency bass sounds between 30 and 60Hz were the most effective.
