    Study Notes

    Ventilation Operations Equipment

    • Full PPE including SCBA is required for Ventilation Sector crews
    • Forcible entry tools:
      • Large bolt cutters
      • 30” Halligan bar
      • Flat Head Axe or Sledgehammer
    • Aerial Fall Protection Belt is needed to connect the Firefighter to a ladder while forcing a roof hatch

    Ventilation Operation Phases

    • Two phases: Smoke Containment and Smoke Removal
    • Smoke Containment: prevent smoke from entering hallways and stairwells during extinguishment of the fire
    • Smoke Removal: remove smoke after extinguishment of the fire

    Smoke Containment Steps

    • Immediately pressurize a stairwell using the HVAC system or PPV to:
      • Provide a safe egress for occupants
      • Provide a safe egress for firefighters
      • Prevent smoke movement into the stairwell
    • Do not open roof hatches in uncontaminated stairwells to prevent a chimney effect

    Smoke Removal Steps

    • Hydraulic Ventilation is not recommended in High Rise buildings due to debris being dislodged
    • Fire in Unit and Smoke Contained to Floor of Origin:
      • Use pressure established in the stairwell to open the applicable stairwell door
      • Direct air flow down the corridor and through the unit of origin using the failed or removed window(s) as exhaust opening(s)
    • Fire in a Hallway and Smoke Contained to Floor of Origin:
      • Open the stairwell door and push smoke from the contaminated hallway into the opposite stairwell and out the corresponding roof hatch
      • This must be done in a well communicated and coordinated manner
    • Smoke on Multiple Floors:
      • Use pressure established in the stairwell and start at the lowest contaminated level
      • Open appropriate doors and push smoke from contaminated corridors into the opposite stairwell and out the corresponding roof hatch
      • This must be done in a well communicated and coordinated manner
