What is the result of ventilation-generated patterns in fire investigation?

The presence of holes in floors as a result of ventilation-generated patterns in fire investigation is indicative of the fire's behavior influenced by ventilation. When a fire is subject to ventilation, such as through open windows or doors, it can alter the fire's intensity and movement. As more oxygen is introduced, the fire may burn hotter and create hotspots, causing damage that can result in holes being burned through floors.

This phenomenon occurs because the areas receiving direct ventilation may become over-ventilated, leading to more intense burning in specific locations. The resulting holes can be crucial in fire investigations, as they provide valuable information regarding fire spread, the origin of the fire, and how the fire was influenced by the building's ventilation layout. Understanding these patterns helps investigators determine the cause and progression of the fire, making the identification of holes in floors a critical indicator in fire analysis.
