Study Notes
Fire Sprinkler Systems
- Over a century of successful history in protecting life and property from fire.
- Civilian fire fatalities in buildings with sprinkler systems are extremely rare.
Risk Management Focus
- Actions prioritize property protection when no people are trapped.
- Risk management strategies must align with property protection goals.
Challenges in Large-Space Buildings
- Firefighter challenges include dealing with cold smoke, which flows calmly and is extremely dangerous.
- Presence of cold smoke during initial assessment is significant, indicating potential fire.
- Small amounts of smoke can indicate a substantial fire in large-space buildings.
Fire Dynamics
- Storage configurations (height and type) affect fire behavior; materials can become heavier when wet and may cause collapses.
- Construction features, such as building size and fire-rated enclosures, influence fire containment.
- Large open spaces typically use truss construction, increasing risk of early structural collapse if fire spreads.
Structural and Incident Response
- Partial roof collapses indicate probable compromise of the fire sprinkler system.
- A significant fire incident often requires a first alarm response or greater.
- Presence of hazardous materials necessitates careful monitoring and assessment.
Fire Protection and Ventilation
- Importance of assessing fire detection and protection systems available.
- Ventilation methods include roof vents, skylights, doors, and exhaust systems to manage smoke and heat.
- Ensure adequate water supply for firefighting efforts.
Specific Hazards
- Warehouses storing rolled paper pose a significant fire hazard.
- Historical incident in 1978 where a fire in a paper storage warehouse resulted in the deaths of three Canadian firefighters due to unstable paper rolls during overhaul.
Defensive Operations
- If the fire sprinkler system fails to control a fire, it will escalate rapidly.
- Fire control may require defensive operations, including exterior suppression via master streams, particularly outside of the collapse zone.
