The concentration and nature of smoke produced during a fire is significantly influenced by whether the materials are flaming or undergoing pyrolysis.

When materials are flaming, they typically burn at a higher temperature and produce a more efficient combustion process, which can generate different smoke characteristics, including reduced particulate matter and more complete combustion byproducts like carbon dioxide and water vapor. In contrast, pyrolysis involves the thermal decomposition of materials in the absence of sufficient oxygen, often resulting in more complex and hazardous smoke components such as tar, soot, and volatile organic compounds.

The physical state of combustion (flaming versus pyrolizing) dictates the chemical reactions that occur and, consequently, the types of gases and particulate matter produced in the smoke. This relationship is critical in fire safety and smoke management, influencing smoke control strategies and the design of effective fire protection systems. Understanding this dynamic helps fire protection specialists predict the behavior of smoke during a fire event, ultimately guiding responses and mitigating risks to life and property.

While the other factors mentioned, such as the time duration of the fire, material age, and fire suppression measures, can affect the overall fire dynamics and smoke production, the immediate nature of the combustion process (whether it is flaming or pyrolyzing) fundamentally shapes the characteristics
