Study Notes
Private Dwellings and Fire Risks
- Over 425,000 fires occur annually in one- and two-family homes in the U.S.
- Private dwellings account for over 70% of civilian fire deaths each year.
- Most residential fires begin below the second story, typically in cellars or on the first floor where heating, electrical, and cooking appliances are located.
- High rates of smoking in living rooms contribute to fire risks.
Firefighting Activities
- Victims inside homes are often found in bedrooms, necessitating focused firefighting tactics.
- Steps for firefighting include securing water supply, positioning charged hoselines to protect exits, and conducting Vent, Enter, Isolate, and Search (VEIS) of occupied areas.
Issues in Design and Construction
- Open stairways, common in two- and three-story homes, act like chimneys, enabling fire and gases to rapidly rise.
- Building codes often lack provisions for fire-resistant interior finishes, leading to faster fire spread due to weak construction.
- Modern open floor plans create larger fire areas, increasing the need for higher water flow for effective firefighting.
Modern Home Design Challenges
- Contemporary homes often feature open-concept living spaces, making fires more challenging to contain.
- Older homes typically had smaller, compartmentalized rooms, facilitating easier fire containment.
- Floor areas in luxury homes can exceed 8,000 sq ft, similar to older commercial buildings.
Initial Response by Fire Officers
- First arriving fire officers must assess structure size and age to formulate appropriate tactical responses.
- Unusual features (e.g., home theaters, indoor pools) may require commercial firefighting approaches.
Tactical Approach to Suppression
- Immediate water flow onto the main body of fire is critical and should target areas between the fire and potential occupants.
- Backup hoselines should be deployed to ensure effective coverage and response to unexpected fire spread.
- Planning for at least three hoselines is advisable to prepare for intense or spread-out fires.
Water Supply Considerations
- A water supply should support three lines flowing about 400-600 gallons per minute, with additional flow for exposure protection.
- Efficient water supply may involve large-diameter hoses from hydrants directly to the fire scene.
Firefighting Operations
- Firefighters must prioritize search and rescue to ensure occupant safety during operations.
- Teams of firefighters should allocate tasks effectively based on personnel availability to address both suppression and search duties.
- The initial attacking hoseline should protect stairways and facilitate access to occupied areas.
Search and Rescue Protocol
- All team members must engage in both search and attack tactics, particularly if separate search teams are unavailable.
- Unaccounted occupants necessitate dedicated search efforts on every floor, especially upper levels.
- Quick response and efficient allocation of resources are crucial for maximizing safety during firefighting operations.
