WHAT IS THE FIRE TETRAHEDRON?
To understand how to prevent fires, it is important to know how a fire can occur. Four elements must be present at the same time for a fire to take place:- Fuel or combustible material - something to burn, such as paper or wood.
- Heat - to raise the material to its ignition (burning) temperature.
- Oxygen - to sustain combustion (the fire).
- Chemical reaction - the process of burning.
