What is the correct order to search for the area of origin in a fire scene?

The correct order to search for the area of origin in a fire scene is to start from the area of least damage to the area of most damage. This approach is crucial because the area that has sustained the least amount of damage is likely to provide important clues about the fire's origin and how it spread. Investigators can better identify potential ignition sources and other relevant evidence when they begin their search in areas where the fire likely started, rather than moving directly toward the most damaged areas, which may obscure important details and make it more challenging to unravel the fire's cause.

Investigators aim to gather data about how the fire progressed and any available evidence that might indicate its source. By starting in the less charred areas, they can ascertain the conditions present before the fire's spread, which is essential for understanding the dynamics of the fire.
