Fire is a fascinating and dangerous phenomenon that plays an essential role in our daily lives. Whether used for heating, cooking, or powering engines, fire has proven to be a vital tool for human advancement. However, when uncontrolled, it can pose a severe threat, causing destruction and loss of life. In this article, we will explore the essence of fire, the principles that enable it, and how to stay safer by understanding fire classifications.
Fire is a chemical reaction known as combustion, which occurs when fuel and oxygen combine with sufficient heat to cause ignition.
In simple terms, three components are necessary to ignite a fire: fuel, oxygen, and heat. These three components are commonly referred to as the fire triangle. If any one of these three components is missing, there will be no fire.
Fire Triangle
Fuel
A combustible material consumed during the combustion process. In a typical workplace, fuels may include paper, cardboard, wooden furniture, gasoline, diesel, butane, acetylene, and other gases, solvents, and chemicals.
Oxygen
In sufficient amounts to support combustion. Oxygen is present in the air at a concentration of 21%. During a fire, oxygen may also come from other sources, including oxygen-rich chemicals (commonly referred to as oxidizing agents), such as ammonium nitrate.
Ignition Source (Heat)
Sufficient to raise the temperature of the fuel to its ignition point.
