How do you explain the fire triangle?
The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen). A fire naturally occurs when the elements are present and combined in the right mixture. A fire can be prevented or extinguished by removing any one of the elements in the fire triangle.
Why is the fire triangle important?
It is composed of three elements – fuel, heat and oxygen – which must all be present for a fire to ignite. It also demonstrates the interdependence of these ingredients in creating and sustaining a fire and teaches us that removing any one of these elements would prevent or extinguish the fire.
What is the new idea of the fire triangle?
The fire triangle was changed to a fire tetrahedron to reflect this fourth element. A tetrahedron can be described as a pyramid which is a solid having four plane faces. Essentially all four elements must be present for fire to occur, fuel, heat, oxygen, and a chemical chain reaction.
How do you stop the fire triangle?
The fire triangle is a symbol that shows the three things that are required for a fire to burn, namely: oxygen….Removing fuel.
|Removal||Method||Type of Fire|
|Oxygen||Fire blanket, CO 2 extinguisher||Oil fires, chip-pan fires, electrical fires|
What happens when 3 elements of fire triangle combine?
The fire triangle's three sides illustrate the three elements of fire: heat, fuel and oxidization. The three elements must be combined in the right proportions for a fire to occur. If any of the three elements are removed, the fire is 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 oxygen in fire triangle?
Oxygen. To sustain the combustion reaction, oxygen (or an oxidising agent) is needed, as it reacts with the burning fuel to release heat and CO2. Earth's atmosphere consists of 21% oxygen, so there is plenty available to trigger a fire if the other two components are present.
What are the 4 main stages of fire?
Compartment fire development can be described as being comprised of four stages: incipient, growth, fully developed and decay (see Figure 1).
What is called fire?
Fire is a chemical reaction that converts a fuel and oxygen into carbon dioxide and water. It is an exothermic reaction, in other words, one that produces heat.
What are the 3 goals of fire prevention?
The goals of fire-prevention programs include preventing loss of life, property damage, and downtime in use of a building.
How do you calculate FIRE?
How to Calculate Your FIRE Number
- Annual Expenses x 25 = FIRE number.
- Annual Expenses ÷ 0.03 = FIRE number.
- Household expenses: mortgage/rent, utilities, cable, internet, general maintenance, household supplies, property tax & insurance, credit card payments.
- Meals: groceries, beverages, dining out.
What does FIRE stand for?
Financial Independence, Retire Early movement
FIRE is an acronym for the Financial Independence, Retire Early movement. The goal of the FIRE movement is to work hard, live below your means and retire early while maintaining a reasonable lifestyle.
What are the 3 elements of FIRE?
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.
