The chemical reaction between each of the three elements can only occur when all three are present. The fundamental principle of the fire triangle is that each element is dependent on the other in the creation and growth of any fire, whilst also demonstrating the complete removal of just one element can prevent a fire or extinguish it entirely.
Fire blankets and certain fire extinguishers remove the oxygen ‘side’ of the triangle by removing it or displacing it, causing suffocation and thereby ceasing the combustion reaction. Fire Triangle Facts. Normal air …
How do fire extinguishers work? – Explain that Stuff
Artwork: The four main types of extinguishers and how they break the fire triangle. 1) Water extinguishers work mainly by cooling (removing heat), but a dense spray of water droplets also helps to cut off oxygen.
The fire triangle illustrates the three elements a fire needs to ignite. These elements include: Heat. Fuel. Oxygen. A fire occurs when these elements are present and combined in the right mixture. The combination of these elements results in an exothermic reaction, or release of heat. Fires can be classified into five different types:

What is a 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. See if Fire Action can help your business. Get in touch with our team to find out more.
How does a dry fire extinguisher work?
Dry chemical extinguishers are tanks of foam or dry powder with compressed nitrogen as the propellant. They work by smothering the fire: when you put a layer of powder or foam on the fire, you cut the fuel off from the oxygen around it, and the fire goes out.
How important is the design of a fire extinguisher?
One thing to note is that the design of a fire extinguisher‘s nozzle is as important as (often more important than) the rest of the mechanism, because how the extinguishing chemicals arrive at the fire is critical. That’s why a lot of patents focus on the specifics of the nozzle.
What does a fire extinguisher look like?
Most of the extinguisher is filled with water (blue). A tube runs right up the inside of the tube to a nozzle outside (gray). The nozzle often ends in a piece of bendy plastic so you can easily direct it toward the base of a fire. To operate the extinguisher, you pull the ring and press the handle.
