Brandpatroon

Brandpatroon, also known as a burn pattern, refers to the characteristic shape and distribution of fire damage at a fire scene. Fire investigators analyze brandpatronen to determine the origin and spread of a fire. These patterns are created by the way heat, flames, and smoke interact with combustible materials.

The most common type of brandpatroon is the "V" pattern. This pattern forms as flames rise and spread outwards from a single point of origin, resembling an inverted V. A narrow "V" often indicates a low-intensity fire, while a wider "V" suggests a more intense or prolonged burn. Another significant pattern is the "U" pattern, which can indicate a fire that has burned in a corner or around an obstruction.

Other brandpatronen include pooled patterns, which occur when a liquid accelerant burns on a horizontal surface, leaving a distinctive, often circular or irregular shape. Stair-step patterns can reveal the path of fire as it ascends or descends a structure. The depth of charring on materials also provides clues about the duration and intensity of the fire in a specific area.

The analysis of brandpatronen is a crucial element in fire investigation, helping to distinguish between accidental fires and those that may have been intentionally set. By understanding the physics of fire behavior and how it interacts with different materials, investigators can reconstruct the events that led to a fire and determine its cause. Environmental factors such as ventilation, fuel load, and the presence of fire suppression systems can all influence the appearance of brandpatronen.
