Study Notes

Tender Operations

Second tender automatically assigned for supplemental water requests or specific call types.
Consider appointing a Water Supply Officer for efficient resource management.

Offensive Mode

Involves firefighters advancing into the fire building with hoses or extinguishing agents to overpower the fire.
All personnel must adhere to Personal Accountability and Two In-Two Out Rule.
Initial Attack Strategy:
- After ensuring no rescue profile, choose Offensive Mode when fire is controllable and structural failure is unlikely.
- Tactical priority order for hose line placement:
  - Rescue (best chance of saving lives and protecting egress).
  - Exposures (protect nearby structures).
  - Confinement (contain the fire).
  - Extinguishment (put out the fire).
Extinguishment tactics typically involve using a solid or straight water stream directed at the ceiling.

Hose Line Types

Pre-connected Hose Lines:
- Notable types include 1¾” Cross lay(s), Front bumper line, and 2½” Blitz-line.
Static Hose Packs are used for longer stretches and allow rapid deployment.
Back-Up hose lines should match Fire Attack lines in size and capability, primarily for firefighter protection.

Flow Path Awareness

Defined as the volume between inlet and exhaust that allows heat and smoke movement.
Operations in the flow path increase firefighter risk; limiting flow paths is crucial until water can be applied.

Incident Action Plan (IAP) Evaluation

Incident Commander must continuously assess the IAP and predict fire behavior to position crews effectively.
Reevaluation necessary based on Fire Conditions and Progress Reports.

Defensive Mode

Engaged when:
- Life cannot be saved.
- Little potential for property preservation exists.
- Resources are insufficient for Offensive operations.
Firefighters must stay outside the collapse zone, which is 1½ times the building height.

Exposure Control in Defensive Mode

Utilize large-capacity streams (min 200 GPM with a 2½” hose line).
Ground monitors and mounted deck guns are preferred for safety and effectiveness; they can operate unattended if in a collapse zone.

Control Zones

Control Zones exist even without visible markings; understanding them remains critical.
Defined as:
- Exclusion Zone: Extremely dangerous area; no entry allowed.
- Hot Zone: High-risk area near the fire.
- Warm Zone: Area with lower risk, away from immediate fire.
- Cold Zone: No risk area, ideally located uphill and upwind from the fire.

Overhaul Operations

Focus on exposing hidden fires and ensuring complete extinguishment post-incident.
Follow priorities of Life Safety, Incident Stabilization, Property Conservation, and Evidence Preservation.
Utilize tools like Thermal Imaging Cameras for effective hazard identification.
Blown-in cellulose insulation is a significant rekindle hazard requiring precaution.
