Study Notes
Building Construction Overview
- Type I construction buildings are highly collapse resistant compared to others; they are often made with noncombustible materials.
- Multi-story buildings with flat roofs commonly use the same structural system for both roof and floors, enhancing uniform support.
- The sill is the lowest horizontal member of a window frame that supports the window hardware.
Fire Doors and Safety Features
- Fusible links on swinging fire doors rely on heat to close, potentially allowing significant smoke to pass before closure.
- Rain roofs conceal fires by creating void spaces, making detection and suppression difficult.
- Lightweight truss components are particularly vulnerable to early failure when exposed to fire.
Firefighter Operations and Building Design
- Overhead rolling steel fire doors typically close by gravity when the fusible link melts.
- Proper maintenance of fire doors is crucial; they effectively limit fire spread when functioning correctly.
- Green roofs can complicate ventilation operations and hinder fire detection efforts.
Types of Windows and Fire Hazards
- Jalousie windows consist of multiple sections that swing outward for ventilation.
- Prefabricated wood truss systems in Type III buildings are prone to quick failure under fire conditions.
- Solid-core doors offer the best fire barrier protection due to their construction materials.
Roof and Structural Considerations
- Roof security features like wired glass complicate ventilation efforts during firefighting.
- Unprotected stairs can serve as pathways for smoke and fire gases, increasing risks.
- Photovoltaic cells on roofs maintain electrical output even when damaged by fire, requiring caution during ventilation.
Fire Construction Types
- Type IV construction is often seen in churches and helps prevent unseen fire travel due to a lack of voids.
- Type V buildings typically feature exterior load-bearing walls made entirely of wood, impacting fire spread dynamics.
- Fire separation walls serve crucial roles by extending from foundations to above the roof, protecting adjacent structures.
Ventilation Challenges
- When performing vertical ventilation, be cautious of decking material applied over rafters that may hinder accessibility.
- Fires in basements pose unique hazards, primarily due to limited ingress/egress compared to above-ground locations.
- Parapet walls on roofs can obstruct firefighters' view, complicating operational assessments.
Door Mechanics and Regulations
- Sliding doors are not suitable for egress pathways as they can impede fast movement during emergencies.
- Folding doors, often classified as horizontal fire doors, are designed to compartmentalize spaces effectively.
- Glass doors must be constructed of tempered glass as per building codes for added safety.
Key Structural Elements
- Arched roofs derive their weight support mainly from exterior walls, influencing firefighting techniques and strategies.
- The type of material used in door construction significantly influences its effectiveness as a fire barrier.
- Understanding window types, such as single-hung windows, helps in identifying escape routes and ventilation strategies during emergencies.
