What characterizes saddle burns in fire investigations?

Saddle burns are specifically characterized as U-shaped burns on floors and ceilings resulting from specific fire dynamics. This pattern typically occurs in situations where heat from a fire has been concentrated or funneled through a space. The U-shape happens when flames rise and hit a surface, leading heat to accumulate and leave a distinct burn mark in the shape of a U.

This pattern can often be found in corners or where surfaces converge, such as near walls, ceilings, or areas with obstructions that direct the flow of hot gases and smoke. The distinctive U-shaped nature of these burns clearly differentiates them from other burn patterns, making them an important aspect of fire investigation to determine the fire's origin and spread. Understanding saddle burns helps investigators analyze how the fire developed and the conditions that influenced its behavior during the incident.
