Study Notes
Fire Triangle
- Represents the fundamental elements required for combustion: fuel, oxygen, and heat.
- Removing any single element from the triangle will extinguish the fire.
- Considered the oldest and simplest model of fire behavior.
Fire Tetrahedron
- Expands upon the fire triangle by adding a fourth element: the chemical chain reaction.
- Emphasizes the necessity of a continuous chemical reaction for flaming or gas-phase combustion.
- Highlights that fire serves as an example of gas-phase combustion, illustrating the complexity of fire dynamics.
