Fire is a natural part of life, providing warmth, light, and energy. However, it can also be dangerous and destructive. Understanding essential firefighting knowledge can help you prevent fires and respond safely if one occurs. This article aims to provide a comprehensive guide to firefighting knowledge that is valuable for everyday safety.

Understanding Fire Behavior

Basic Fire Triangle

To understand fire, you need to know the basics of the fire triangle. The fire triangle consists of three components:

  1. Fuel: This can be anything that can burn, such as wood, paper, or gasoline.
  2. Heat: Fire needs heat to ignite fuel. This can come from a spark, flame, or high temperatures.
  3. Oxygen: Oxygen is the oxidizer that allows fuel to burn.

Fire Classes

There are different classes of fires, each requiring a specific type of extinguisher:

  • Class A: Ordinary combustible materials such as wood, paper, and cloth.
  • Class B: Flammable liquids and gases such as gasoline, oil, and grease.
