Which of the following is NOT a type of fire pattern on walls and ceilings?

The concept of fire patterns is critical in fire investigation as it helps to determine the origin and spread of a fire. Each of the types listed involves specific mechanisms and behaviors that occur as a result of heat and smoke movement during a fire.

Plume generated patterns refer to the markings left by the movement of hot gases and flames as they rise from the fire source, creating a distinctive pattern on walls and ceilings. Ventilation generated patterns are associated with how airflow affects the fire's behavior, including how smoke and heat move through a structure, often influenced by windows, doors, and other openings. Hot gas layer patterns are formed due to the stratification of heat and smoke gases above the fire in a room, which can create observable patterns on horizontal surfaces.

In contrast, smoke generated patterns, while indicative of smoke movement and behavior, are not recognized as a specific type of fire pattern in the same manner as the other three options. Therefore, this term does not specifically align with the established categories of fire patterns that investigators use to analyze fire behavior and identify the fire's origin.
