A simple model for understanding the cause and development of each fire, the fire triangle lists the essential elements of any fire. To understand how to stop combustion and put out a fire, it is crucial to comprehend the triangle’s three main principles.
The three components of the fire triangle—oxygen, heat, and fuel—simplify and define the elements for fire initiation and growth. Only when all three are present can the chemical interaction between each of the three components take place.
The basic principle behind the fire triangle is that each component is necessary for the initiation and spread of any fire, but it also shows how the loss of just one component can stop or completely put out a fire.
Always keep in mind the fire triangle while thinking about fire safety. A continuing fire can start to decrease if any one of the fire triangle’s components is removed. If you take away even one of these, the fire will stop burning.
Oxygen
Heat
Heat automatically comes to mind when you think about fire. One of the best ways to weaken and ultimately put out a fire is to reduce its heat. A good example of this would be to blow out the flame of a candle. The candle stops burning when the heat is removed from it by the swiftly moving air. Heat not only increases the likelihood that a fire will start but also helps keep one going by eliminating moisture from fuel sources and warming the surroundings, making it easier for the fire to spread.
Water effectively absorbs the heat from a fire, making it a helpful tool for eliminating a fire’s heat. However, water should never be used to put out electrical fires since doing so increases the risk of electric shock, or oil fires because doing so makes the fire worse since oil and water do not mix.
The combustion reaction requires oxygen because it combines with the burning fuel to produce heat and CO2. Because the Earth’s atmosphere contains 21% oxygen, there is ample available to start a fire if the other two components are present. When at all feasible, try to suffocate a fire by smothering it with the most suitable sort of fire extinguisher, water, or a covering substance like earth.
A carbon dioxide extinguisher or a fire blanket can be used to remove oxygen from the area around the fire. The carbon dioxide extinguisher pulls oxygen away from the fire and replaces it with non-flammable, denser-than-air carbon dioxide. Fire blankets create a barrier around the fire to keep it from getting extra oxygen. Another method of drawing away oxygen would be closing doors during an evacuation of a building. This stops a new supply of oxygen from entering.
Fuel
Any fire needs a fuel source—something that burns—to get going. Paper, wood, textiles, plastic, and various gases are common flammable materials. Fire-resistant materials are beneficial because they prevent potential fires from having a fuel source to support their spread.
The removal approach is not always the best way to put out a fire; rather, it only slows its growth and prevents it from spreading. A fire will burn until all the fuel is consumed or intervention measures, such as removing heat and/or oxygen, have been used.
This is a very successful way of fire protection because, by employing fire-resistant materials, any fire will not have enough of a fuel supply to keep burning. Clothing, furniture, and construction materials may all be made with fire-resistant materials. If the trees surrounding a fire can be cut down to stop it from spreading, forest fires can also be controlled more successfully. This strategy is called a firebreak.
Water effectively absorbs the heat from a fire, making it a helpful tool for eliminating a fire’s heat.

Extinguish Fires Effectively
By going through the fire triangle’s foundational principles, the necessary procedures for talking about fire safety are simplified. To put out a fire, you must remove one element from the fire triangle. The fire triangle’s guiding principles have played a significant role in the creation of fire extinguishers.
The fire triangle establishes what must be done in the event of a fire, as well as the essential preparation and procedures required to avoid the first lighting of the fire. All the principles should be considered in the revision or application of fire safety training and regulations.
