Where is the deepest char likely to be found in a fire scene?

The deepest char at a fire scene is typically found near the area of origin. This is because the intensity and duration of heat are usually greatest at the source of the fire. As the fire develops, materials in the area of origin are subjected to prolonged exposure to flames and high temperatures, which results in more severe charring.

Near the area of origin, the combustion process is most active, leading to a greater depth of char on the surfaces of burned materials. The char itself is a product of incomplete combustion, and the depth increases as the heat and flames interact with the materials for longer periods.

In contrast, as one moves further away from the origin, the intensity of the heat diminishes, leading to shallower charring. Focusing on the specific characteristics of each fire scene reveals this pattern, making it clear why the area of origin is where the deepest char is most frequently encountered.
