Study Notes
Combination Attack Method
- Utilizes hose stream to cool combustible gases at ceiling level, facilitating the advance of the nozzle team.
- Effective for confined residential fires, typically around 10x12 ft, allowing for attacks from the doorway.
- For larger fires, a continuous attack while advancing is necessary to address all involved surfaces.
Advanced Firefighting Strategy
- Initially, apply water at ceiling level for 5-10 seconds, then sweep the contents of the room until fire darkens.
- Use the straight stream setting to engage the next room and cool the floor to mitigate risks from embers and debris.
- A "Z" pattern is recommended for sweeping the ceiling, followed by sweeping the floor to extinguish flames effectively.
Risks and Tactical Errors
- Firefighters entering involved structures face considerable risk; due diligence is crucial to ensure safety.
- Common errors include:
- Using a wide fog pattern on the fire, which can produce steam, potentially forcing the team out of the area.
- Leaving the stream on the ceiling too long without addressing the actual burning fuel in the room, hindering extinguishment efforts.
Understanding Fire Stages
- The smoldering stage occurs when a fire hasn’t visibly burned but can still produce toxic gases and heat, posing backdraft risks.
- This dangerous condition can arise from energy conservation methods that create airtight buildings, trapping heat and gases inside.
Backdraft Prevention Techniques
- Suspected backdraft conditions require venting the highest portions of the area, typically through the roof.
- Cutting proper ventilation openings can be challenging, and alternative methods may need to be employed in time-critical situations.
Indirect Attack Strategy
- If traditional ventilation is impractical, the indirect attack can be employed, especially effective during third-stage fires.
- Small openings should be created for water application, utilizing a 30° fog pattern that vaporizes instantly, absorbing heat and generating steam to create an inert atmosphere.
Post-Attack Strategies
- After using the indirect method, if conditions allow, shift to a combination attack to eliminate remaining fires.
- Allow steam to soak the area for several minutes to prevent reignition, especially critical in multistory buildings where robust follow-up resources are unavailable.
