Fire extinguishers are essential devices that can help you stop small fires before they become uncontrollable. But do you know how to choose the right fire extinguisher for the type of fire you are facing? In this video, we will explain the fire extinguisher ratings, which are designed to help you understand the class and size of a fire that an extinguisher can put out. We will also show you some examples of different types of fires and the best extinguishers to use for them. Types of fire extinguisher and their uses | In Hindi : https://youtu.be/AH-hustLoYA

Fire extinguisher ratings are indicated by a letter and a number, such as 13A or 55B. The letter corresponds to the class of fire, which are:

- Class A: Fires involving ordinary combustible materials, such as wood, paper, cloth, rubber, and plastics.
- Class B: Fires involving flammable liquids, such as petrol, diesel, oil, paint, and solvents.
- Class C: Fires involving flammable gases, such as propane, butane, methane, and acetylene.
- Class D: Fires involving combustible metals, such as magnesium, lithium, titanium, and potassium.
- Class F: Fires involving cooking oils and fats.

The number indicates the size of fire that the extinguisher can put out under test conditions. The higher the number, the larger the fire it can extinguish. For example, a 13A extinguisher can put out a fire made of 144 pieces of wood stacked in a crib, while a 55B extinguisher can put out a fire made of 55 liters of flammable liquid in a tray.

To choose the right #fire extinguisher for your situation, you need to consider both the class and the size of the fire. For example, if you have a small fire in your kitchen involving cooking oil, you should use a class F #extinguisher  with a high rating. If you have a large fire in your garage involving petrol or paint, you should use a class B extinguisher with a high rating. If you have a small fire in your office involving paper or wood, you should use a class A extinguisher with a low rating.  

It is important to note that some fire extinguishers can be used for more than one class of fire. For example, water-based extinguishers can be used for class A and F fires, while dry powder extinguishers can be used for class A, B, C and D fires. However, you should always check the label of the extinguisher before using it to make sure it is suitable for the type of fire you are dealing with.

In this video, we will demonstrate how to use different types of fire extinguishers on different types of fires. We will also give you some tips on how to prevent fires from starting and spreading in your home or workplace. Stay tuned and don't forget to subscribe to our channel for more videos on fire safety.
