fireground flow path

Fireground flow path refers to the movement of heat and smoke from higher pressure areas inside a burning structure toward lower pressure openings such as doors, windows, or ventilation points. This flow path significantly influences fire behavior and firefighter safety by directing the movement of flames, smoke, and hot gases. Not to be confused with water flow path, which relates to hose line deployment and water application, fireground flow path is critical in understanding ventilation tactics and risk assessment during interior firefighting operations under the Incident Command System (ICS).
