What is the significance of identifying products of combustion?

Identifying products of combustion is crucial in understanding the fire's spreading pattern. When fire investigators analyze the specific gases and particles produced during combustion, they can ascertain how the fire evolved and moved through the structure. Different materials produce distinct combustion products, which can indicate the temperature and conditions of the fire. For instance, certain materials might emit smoke that carries different chemicals depending on their composition, which can give valuable clues about how the fire spread and affected various locations within a space.

Understanding the byproducts also enriches the investigation by revealing the potential pathways for fire spread, whether through direct contact with materials or via the movement of smoke. This knowledge is essential for accurately depicting the fire dynamics at play during an incident, ultimately providing insights for reconstruction and analysis of fire behavior.
