Definition & Operational Usage
The fire triangle is a foundational concept in fire science that illustrates the three essential elements required for combustion: heat, fuel, and oxygen. Each component plays a critical role in the fire's behavior and sustainability. Not to be confused with the fire tetrahedron, which includes a fourth element—chemical chain reaction—the fire triangle is integral to strategies such as START and ICS for effective fireground operations. Understanding this model aids in the tactical decision-making process during suppression efforts.
