The Four Stages Of A Fire

3/4/2020 (Permalink)

When a fire breaks out, it actually occurs in four different stages, from incipient to decay.  This takes the fire from ignition to when it is extinguished. Each stage can cause different types of damage that SERVPRO of Trumbull, Monroe & Northern Bridgeport can remediate.

Incipient

This stage starts when heat, oxygen and a fuel source undergo a chemical reaction, which results in the ignition of a fire.  This is a small flame that does have the chance to go out by itself. Catching a fire in this stage gives people the best chance to either put out the fire, or get out of the building.

Growth

This stage is when a fire begins to build.  Factors that affect the rate of growth include the amount of oxygen in the environment, nearby combustible items, and ceiling height. This stage of the fire is the shortest in duration, but is the stage when a flashover can occur.  A flashover is when combustible items in the environment will ignite without warning. 

Fully Developed

This is the hottest stage of the fire.  At this point, the fire has consumed most, if not all of the combustible materials in the environment.  This can include furniture, clothing, wood, and flammable liquids. For inhabitants on a home or business, this is the most dangerous stage, due to the high heat and the potential for smoke inhalation.

Decay

This stage begins when the fire has no more source of fuel, whether that be oxygen or flammable materials.  The decay stage is usually the longest, especially if no external efforts are made to extinguish the blaze. If the fire is not fully put out, an influx of oxygen can reignite the fire.
