The fire triangle is a simple way of understanding the elements of fire. The sides of the triangle represent the interdependent ingredients needed for fire: heat, fuel and oxygen .
How significant are the 3 elements of fire triangle?
The fire triangle, or combustion triangle, is the three components needed to ignite and sustain a fire. The three ingredients of a fire triangle are; heat, fuel and oxygen . ... If just one of these components is removed, the fire triangle will collapse and the fire will be extinguished.
What are the elements of fire triangle?
Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
What is the fire triangle and its composition?
Something usually taught in school, the fire triangle (which is also known as the combustion triangle) is a simple model for understanding the chemical reaction which must occur to create a fire. It is composed of three elements – fuel, heat and oxygen – which must all be present for a fire to ignite.
How many elements are in the fire triangle?
The combustion triangle or fire triangle is the three components required for igniting and sustaining a fire. Oxygen, fuel, and heat are the three ingredients of a fire triangle.
What are the 3 components of fire triangle?
Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
What is the most important element of fire?
The first element in the fire triangle is heat , which is perhaps the most essential of fire elements. A fire cannot ignite unless it has a certain amount of heat, and it cannot grow without heat. The fire triangle’s three sides represent heat, fuel and oxidization.
What is the best Defence against fire?

- Fire alarm and fire fighting equipment signs.
How do you explain the fire triangle?
The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen) .
How many classes of fire are there?
Fire is divided into five classes (A, B, C, D, and K) that are primarily based on the fuel that is burning. This classification system helps to assess hazards and determine the most effective type of extinguishing agent.
What are the 4 stages of a fire?
Compartment fire development can be described as being comprised of four stages: incipient, growth, fully developed and decay (see Figure 1).
What is a Type C fire?
Class C. Class C fires involve energized electrical equipment . Extinguishers with a C rating are designed for use with fires involving energized electrical equipment.
What is man made fire?
Man made causes – Fire is caused when a source of fire like naked flame , cigarette or bidi, electric spark or any source of ignition comes into contact with inflammable material.
How can you prevent a fire?
- Create and practice a fire escape plan. Include two ways out of every room. Pick a spot to meet outside. ...
