What does pyrolysis refer to?

• A. The process of combining oxygen with combustible materials
• B. The chemical reaction that produces gas
• C. The decomposition of solid organic matter by heat
• D. The oxidation of materials in a fire

Answer: (C)

Pyrolysis refers to the thermal decomposition of solid organic materials through the application of heat. This process occurs in the absence of oxygen, leading to the breakdown of complex organic molecules into simpler compounds, including gases, liquids, and char. Pyrolysis is a crucial concept in understanding fire behavior because it is one of the initial stages of combustion. It occurs before ignition, where the material breaks down and releases flammable gases that can ignite when exposed to a spark or flame. This process is relevant to firefighters as it impacts how materials behave in a fire, influencing the fire's growth and potential hazards. Recognizing pyrolysis helps in predicting fire development and implementing appropriate firefighting strategies.
