✗ The myth everyone repeats
Fire is a simple process requiring only three ingredients: oxygen, heat, and fuel (the fire triangle).
✓ What is actually true
The fire triangle is an oversimplification. Modern chemistry describes combustion as a chain reaction requiring not just the three components, but an ongoing chemical reaction. The fire tetrahedron (adding chain reaction) is more accurate. Oxygen alone doesn't cause fire without sufficient heat and fuel combining properly. Some fires burn without oxygen using other oxidizers.
