Combustion Basics - How a Fire Breaks Out Streaming Video on Demand

Fire is a force of nature we often fear, but rarely stop to understand. To the untrained eye, it appears as a chaotic burst of heat and light. But to a safety professional, fire is a predictable, rapid chemical reaction with specific requirements and behaviors. This course, "Combustion Basics," strips away the mystery and takes you into the molecular heart of how a fire breaks out.

We begin by defining the event itself. Fire is not an object; it is a chemical process. Specifically, it is a rapid reaction between oxygen and a combustible material, resulting in the release of energy in the form of heat and light—what we know as "flames." However, the flames are only part of the story. You will learn about the often-overlooked byproducts of this reaction, including water vapor and, more dangerously, smoke. We delve into the composition of smoke, explaining why it is often more lethal than the fire itself due to the presence of deadly particulates and harmful chemicals that can incapacitate a person in seconds.

Central to this training is the concept of the "Fire Triangle." Just as a stool needs three legs to stand, a fire needs three specific elements present simultaneously to exist: Oxygen, a Heat Source, and a Combustible Material (Fuel). For the "motorheads" among us, you might know this better as "spark, air, and fuel." We will break down each leg of this triangle in detail. You will learn how oxygen acts as the oxidizer, how fuel provides the material for the reaction, and how heat brings the fuel to its ignition temperature.

Crucially, we explore how these elements interact to sustain a fire. It is not enough to simply have the elements present; they must be available in high enough quantities to maintain the chemical chain reaction. This concept is the key to all fire safety and suppression.

Finally, we translate this theory into practice. You will discover that every fire extinguisher, sprinkler system, and fire blanket works on the same simple principle: removing one leg of the Fire Triangle. Whether it is a blanket blocking the oxygen or water cooling the heat source, if you break the triangle, you kill the fire. By the end of this course, you will not just see a fire; you will see a chemical equation that you have the power to solve.
