Study Notes
Transitional Attack
- Transitional attack involves applying water directly to burning areas from outside a building before transitioning to interior attack.
- Critical to assess the fire's location and potential threats to life or exposures before deciding on the first hoseline's position.
- Place hoselines between the fire and any occupants, or aim to protect exposures when necessary.
Factors for Decision-Making
- Consider if the volume of fire is too large for initial hoseline extinguishment, requiring a holding position for exposure protection.
- If fire is on upper floors, hoselines should be stretched to the location of the fire rather than taking longer routes through the structure.
- Knowledge of how quickly additional hoselines can be deployed informs strategy selection.
Firefighting Considerations
- Using exterior streams is beneficial for quick knockdown but is unlikely to achieve complete extinguishment.
- Initial water application should be brief (15-20 seconds) to avoid trapping firefighters in smoke and heat.
- Attack the fire immediately in areas that threaten egress, especially when there's arson suspected or in hazardous locations.
- Avoid attacking from the unburned side in the presence of wind, as this can lead to dangerous conditions for firefighters.
Exposure Protection Strategies
- Protecting the most severe exposure is crucial when life hazards are not present.
- Evaluate the extent of the fire and the attack capability of firefighting units to decide on hoseline placement.
Hoseline Selection and Positioning
- Firefighters with limited hose diameter may focus on exposure protection rather than interior attacks.
- Large diameter lines and master streams significantly enhance firefighting capabilities against major threats.
Factors Impacting Exposure Threats
- Size and proximity of window openings amplify fire energy; targeting windows with effective techniques can help manage threats.
- Radiant heat poses a significant risk, necessitating adequate distancing from the fire source to protect exposures.
- Fire behavior varies depending on building construction; frame structures are particularly susceptible to rapid fire spread.
Prioritize Rescues and Fire Control
- Employ a systematic approach of rescue, confinement, and extinguishment during firefighting operations.
- Be vigilant of radiant heat and properly direct water streams to mitigate risks from unseen ignition sources.
Nozzle Functionality and Management
- Nozzles facilitate water management, allowing regulation of flow and pressure during firefighting efforts.
- Proper use of nozzles can enhance fire control and ensure adequate application to threatened surfaces.
