LectureNotes said the fire tetrahedron has four elements, these are oxygen, fuel, heat, and what else?

The fire tetrahedron is a model that represents the four essential components required for a fire to ignite and sustain. These components are:

  1. Oxygen: This is a necessary element for combustion. Without sufficient oxygen, a fire cannot start or continue to burn.
  2. Fuel: This is any material that can combust, such as wood, gasoline, or coal. The fuel provides the necessary material for the fire to consume.
  3. Heat: This is the energy required to raise the fuel to its ignition temperature. Without adequate heat, the fuel will not ignite.
  4. Chemical Chain Reaction: This is the fourth element that differentiates the fire tetrahedron from the simpler fire triangle. The chemical chain reaction sustains the fire once it has started, allowing the fire to continue burning and spreading.

The inclusion of the chemical chain reaction acknowledges that fire is not just a simple combination of heat, fuel, and oxygen, but also involves complex chemical processes that maintain the combustion process.

In summary, the four elements of the fire tetrahedron are:

  1. Oxygen
  2. Fuel
  3. Heat
  4. Chemical Chain Reaction
