What is the first stage of fire called?

The first stage of fire is identified as the incipient stage. During this phase, the fire is just beginning, characterized by the presence of ignition sources and the startup of combustion reactions, typically resulting in small, limited flames. This stage is crucial because it represents the point at which fire can potentially grow and spread if not controlled.

In the incipient stage, the fire growth is primarily dependent on the available fuel and oxygen, and it does not yet pose a significant threat beyond its immediate vicinity. Effective firefighting techniques can interrupt this stage, preventing the fire from advancing to the growth stage, where it begins to develop more fully and can lead to rapid escalation. Understanding this stage is essential for firefighters to make decisive and timely interventions, ensuring safety and minimizing property damage.
