Study Notes
Fire Stream Management
- Fire stream management techniques are defined in this SOP
- Life safety is the top priority when deploying hose lines.
- Incident stabilization and property conservation follow life safety considerations.
- Hose lines should be advanced inside fire buildings to control access to halls, stairways, or other vertical and horizontal channels
- It is the responsibility of each engine company to ensure an uninterrupted, adequate supply of water
- Hose line effectiveness depends on size, placement, speed, mobility, and supply
Ventilation Considerations
- Ventilation decisions significantly impact fireground operations
- Fire growth and development are influenced by air entering and exiting the fire area
- Ventilation openings should be controlled and coordinated with the fire attack
- Uncontrolled forcible entry may lead to firefighter or civilian injury, death, and property loss
- Ventilation should be performed with a purpose, considering the impact of actions
Flow Path
- The flow path is the movement of fire through a structure, determined by inlet and exhaust vents for air
- Increasing ventilation openings can lead to fire growth and spread
- Limiting or controlling openings can limit fire growth
- Keeping doors closed helps limit oxygen and reduces fire temperature
- Each new ventilation opening creates a new flow path, potentially leading to dangerous conditions for firefighters
Horizontal Ventilation
- Forcing entry should be treated as ventilation
- Initial ventilation should involve assessing airflow for ventilation-limited fires.
- Each new opening can result in hazardous conditions if placed between the fire and its spread path
- Fire showing does not always indicate sufficient ventilation
- Horizontal ventilation should coincide with water application
- Commercial buildings may require horizontal openings for egress and ventilation, requiring consideration for their impact
Vertical Ventilation
- Vertical ventilation is a natural method for exhausting heated gases but can also create a potential for air uptake
- Vertical ventilation accelerates airflow and can spread fire along the flow path, increasing growth
- Coordination with the fire attack is crucial
- Avoid working over truss roof systems damaged by fire unless inspected and deemed safe
Wind-Driven Fires
- Wind can significantly impact the flow path
- Windward side ventilation can introduce massive amounts of oxygen into a fire, leading to rapid growth and flow path shifts
- Fire attack and ventilation should consider wind direction, keeping it at your back during attack, and limiting ventilation to the leeward side
Positive Pressure Ventilation
- Positive pressure ventilation is coordinated by the Incident Commander
- Positive pressure ventilation should never occur before the 'water on the fire' benchmark.
Vent, Enter, Isolate, Search (VEIS)
- VEIS is effective for potential victims accessible via windows
- When performing VEIS, minimize flow path creation and drawing fire towards victims
- Avoid venting the window with the ladder, and delay venting the entry window until entry
- Upon entrance
- Upon entry to the room, immediately control the door (flow path)
