Ignition Source Theory

Ignition Source Theory explains how fires start by identifying the initial spark or heat that ignites a combustible material. It suggests that for a fire to begin, there must be a source of energy—such as a spark, open flame, hot surface, or electrical fault—that raises the temperature of fuel to its ignition point. Essentially, it highlights that fires originate from a specific energy source interacting with combustible materials, emphasizing the importance of controlling or eliminating these sources to prevent fires. This theory underpins fire prevention strategies by focusing on identifying and managing potential ignition risks.
