What type of pattern would you expect to find in a fire that burns primarily upwards and outwards?

The V-pattern is commonly associated with fires that burn primarily upwards and outwards. This pattern forms as the heat from the fire causes the flames to rise, creating an upward point where the intensity is highest. As the fire spreads, it often moves outward from that point, which can result in the characteristic “V” shape that is observed when analyzing burn patterns on walls or ceilings.

In fire investigation, the V-pattern is significant because it helps technicians and investigators determine the origin of the fire. By understanding the behavior of flames and smoke, investigators can trace back to where the fire started, as the narrow tip of the “V” generally points toward the ignition source.

Other patterns, like the inverted pattern or conical pattern, would indicate different types of fire behavior that do not correlate with a fire moving primarily upwards and outwards. The radial pattern, on the other hand, may suggest a more uniform spread from a central point, which does not align with the described scenario of upward and outward movement. Focusing on the V-pattern allows for a clearer understanding of the fire’s progression and origin, which is crucial in fire investigation.
