What are the primary products of combustion?

The primary products of combustion are smoke, flame, heat, and light. When a material burns in the presence of oxygen, the chemical reactions that occur produce these observable effects and materials.

Smoke is generated from the incomplete combustion of fuels, containing particulate matter and various gases. Flame represents the visible part of the fire, showcasing the energy released from the combustion process. Heat is a byproduct of combustion that is essential for sustaining the fire and can have a significant impact on surrounding materials. Light emanates from the combustion reaction, primarily due to the excitation of gas molecules and particulates.

Understanding these products is crucial for fire investigators as they provide insights into the combustion process, the behavior of fire, and the potential hazards involved in fire situations.
