In this module, we will learn more about the essential elements of fire. We will discuss the fire tetrahedron in more detail and find out how the four essential elements relate to concepts such as heat of combustion and combustion efficiency.

We will learn how different interactions between the elements of the fire tetrahedron can lead to different types of flames and also how these four elements play a role in determining the structure of fire plumes and how fires might spread.
