Smoke Damage Mitigation
- Hot smoke from a fire spreads throughout the structure unless controlled.
- Positive Pressure Ventilation (PPV) is used during active firefighting to clear smoke.
- Post-fire measures include managing door openings to reduce smoke damage while ventilating.
- Roof ventilation (cutting a hole) is recommended to facilitate smoke removal.
- Quick smoke removal enhances firefighter effectiveness in search, rescue, and salvage operations.
- After extinguishing the fire, it is critical to remove remaining smoke to prevent further contamination.
- Avoid redistributing smoke throughout the building; maintain ventilation during overhaul procedures.
- Smoldering items, like couches, should be taken outside for safe disposal during cleanup.
- In certain situations, it is important to turn off the building's ventilation system to prevent air contamination.
- Air Conditioning (AC) systems can spread smoke and contaminants, posing risks to the air handling system, which may necessitate its replacement.
