Definition & Operational Usage
Hydraulic Ventilation involves utilizing a fog stream from a hose line directed through an opening to effectively remove smoke and heat from a structure. This method generates a negative pressure effect, facilitating the expulsion of contaminated air and enhancing visibility and conditions for firefighters operating within the Hot Zone. Not to be confused with traditional ventilation techniques, hydraulic ventilation is particularly advantageous in scenarios where rapid deployment is essential, such as during initial fire suppression efforts under the Incident Command System (ICS).
