What are the three elements of the fire triangle?

Heat, Fuel, and Oxygen

A flame needs three elements to keep burning: heat to reach ignition, fuel to burn, and oxygen to sustain the chemical reaction. If any one of these is removed, the fire can’t continue. The other options introduce elements that aren’t required parts of combustion: pressure isn’t a fundamental factor for a typical fire; water is a means to remove heat, not a sustaining element; smoke is just a byproduct of burning, not one of the things that must be present. Understanding this helps you see how extinguishing works—cool the heat, remove the fuel, or reduce the oxygen—and why those tactics stop the fire.
