What is your idea about 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..
How many classes of fire are there?
five classesFire 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 is the fire triangle and how do we use it?
The fire triangle is a symbol that shows the three things that are required for a fire to burn, namely: oxygen….Removing fuel.RemovalMethodType of FireOxygenFire blanket, CO 2 extinguisherOil fires, chip-pan fires, electrical firesHeatWaterHouse fires, wood fires, paper firesFuelFirebreakForest fires
What is the most important element of fire?
3 Things a Fire Needs. The 3 things a fire needs are heat, fuel and oxygen. These three elements work together to help a fire start and take over. … 3 Things a Fire Needs. Heat. Heat is the first and most essential element that a fire needs.
What is the best defense against fires?
Fire Extinguishers: Your First Line of Defense Against Fires.
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 are the essential requirements for producing fire?
Three essential requirements are: Fuel. Air. Heat to acquire the ignition temperature.
What are the 5 stages of fire?
These stages are incipient, growth, fully developed, and decay. The following is a brief overview of each stage.
What is the importance 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.
How significant are the 3 elements of fire triangle?
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 role of oxygen in the fire triangle?
Oxygen. … Ambient air is made up of approximately 21% oxygen and, as most fires only require at least 16% oxygen to burn, it acts as the oxidising agent in the chemical reaction. This means that when the fuel burns, it reacts with the oxygen to release heat and generate combustion.
What are the 4 types of fire extinguishers?
There are four classes of fire extinguishers – A, B, C and D – and each class can put out a different type of fire. Multipurpose extinguishers can be used on different types of fires and will be labeled with more than one class, like A-B, B-C or A-B-C.
What is the first rule in fire safety?
When it comes to fire safety, the number one rule is that everyone goes home. Ensuring this starts the moment you drive up on scene with a good scene size up. Assessing the structure, looking for hazards, and calculating the best means of fire attack are some of the first steps to ensuring scene and firefighter safety.
What causes a fire to start?
Fires start when a flammable or a combustible material, in combination with a sufficient quantity of an oxidizer such as oxygen gas or another oxygen-rich compound (though non-oxygen oxidizers exist), is exposed to a source of heat or ambient temperature above the flash point for the fuel/oxidizer mix, and is able to …
What are the five main principles of fire?
Fire Extinguishment PrinciplesCooling of Flame.Reduction of Flame by cooling of the liquid; dilution of the liquid; or blanketing of the liquid.Reduction of oxygen.Interference with Combustion Reaction.Apr 14, 2015
What is a Class C fire?
A class C fire is one in which an energized electrical element is the cause of the fire. “Energized” means that the electrical component (whether electrical appliance, wiring, device, etc.) is connected to a power source.
What will you do in case of fire?
Immediately pull the nearest fire alarm pull station as you exit the building. When evacuating the building, be sure to feel doors for heat before opening them to be sure there is no fire danger on the other side. If there is smoke in the air, stay low to the ground, especially your head, to reduce inhalation exposure.
Why is the fire tetrahedron important?
Essentially all four elements must be present for fire to occur, fuel, heat, oxygen, and a chemical chain reaction. … Each of the four sides of the fire tetrahedron symbolise the Fuel, Heat, Oxygen and Chemical Chain Reaction.
How do you break a fire triangle?
Breaking the Fire Triangle There are various methods to remove one of the elements from the fire triangle such as: applying water to remove heat; smothering with mineral soil to remove oxygen; or constructing a fuel break ahead of the fire to remove fuels.
What makes a fire worse?
Lack of Water: Since water is one way to put a fire out, the lack of water can be a serious problem. … Dust: No one ever thinks about dust making a fire worse, but dust is very dry. If there is enough dust, it can make a fire stronger. Dust burns very fast, making it much harder to contain if the dust is widespread.
