Study Notes

Property Conservation

TFD prioritizes property conservation alongside life safety and fire control efforts.
Resources are committed to minimize property loss; actions must be proactive and aggressive.
Fire streams should be ceased when the fire is under control to prevent water damage.
Recognizing when fire progress stops is crucial for reducing losses.
Personnel assigned to rescue or fire control should be evaluated for fatigue before reassigning to loss control duties.
Early salvage operations play a critical role in minimizing loss during incidents.
Simultaneous fire attack and loss control may require additional resources for effective execution.
Loss control activities should be integrated into the cause and determination phase of the incident.
Non-essential companies should withdraw once fire control is achieved to allow investigations to proceed.
Scene control is necessary to preserve evidence for investigations.
Customer Service Group should engage with occupants or owners to address immediate needs post-incident.

Support Activities

Support activities enhance fire control and rescue operations, including:
- Ventilation
- Utility control
- Scene lighting

Ventilation

Structures should be vented prior to firefighter entry when feasible.
For example, venting a window before interior attack in residential fires can improve safety and effectiveness.

Utility Control

The Incident Commander (IC) is responsible for notifying utility companies and controlling utilities where feasible by TFD.

Scene Lighting

Adequate fireground lighting enhances safety and should be established early during incidents.

Assignment of Support Functions

Traditionally, ventilation, utility control, and lighting are managed by ladder companies, but roles may shift due to operational conditions.
Companies responsible for ventilation must ensure lighting and utility control are also executed or alert the IC if unable to complete tasks.

Fire Streams/Water Supply

Fire stream selection is influenced by fire size, location, strategy, and available water supply; multiple types of streams may be necessary.
Quick fire control is essential for offensive attacks; failure to do so warrants a defensive strategy.
Master streams can serve both offensive and defensive roles; effective application includes short bursts to gain control followed by handline advances.
Do not combine exterior and interior fire stream operations.
Use solid bore nozzles for effective penetration and distance when deploying master streams; be cautious with fog streams in confined spaces to avoid steam hazards.

Specific Equipment Guidelines

1 ¾” Preconnects equipped with SM-20F Fog Nozzle deliver ~100 gpm at 110 psi, sufficient for 600 to 1000 square feet of coverage.
SM-30F fog nozzles primarily utilized on 3" handlines can also be adapted for 1 ¾” lines, offering a potential flow increase of 25% when used in the latter context.
