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
