What does Pyrolysis refer to?

Pyrolysis is a thermal decomposition process that occurs in the absence of oxygen, where organic materials, including both solid and liquid fuels, are subjected to heat. During this process, these materials break down into smaller molecules, leading to the release of gases. This off-gassing can produce flammable vapors and potentially combustible gases, which can ignite in the right conditions.

The choice identifying both solid and liquid fuels off-gassing encompasses the full scope of what pyrolysis entails. In particular, solid fuels such as wood can break down when heated, producing gases that contribute to combustion. Similarly, liquid fuels when heated can also produce flammable vapors. By recognizing that pyrolysis applies to both types of fuels, it highlights the comprehensive nature of the process and its significance in fire behavior and combustion. This understanding is crucial for firefighters when assessing fire dynamics and potential hazards at a fire scene.
