4 Structure Triage Types (IRPG)
- Defensible-Prep and Hold
- Defensible-Standalone
- Non-Defensible-Prep and Leave
- Non-Defensible-Rescue Drive By
Rates of Spread
Slow (very little)
Moderate (< 1 MPH)
Dangerous (1-3 MPH)
Critical (> 3 MPH)
3 structure triage categories
Not Threatened
Threatened Defensible
Threatened Non-Defensible
5 Assessment Items for the Vegetation Management Survey

- Weeds
- Trees
- Dead Palm Fronds
- Combustibles on Property
Structure Defense Tactical Actions
Check and Go Prep and Go Prep and Defend Fire Front Following Bump and Run Anchor and Hold Tactical Patrol

DRAW-D (levels of engagement for wildland firefighting)
Levels of engagement in wildland firefighting
D-Defense: holding actions, defending priority areas
R-Reinforce: bring more resources to bear. Add more resources to defend or advance.
A-Advance: Anchor and Flank. Direct or Indirect attack. Burnout operations.
W-Withdraw: cease current activities until conditions modify
D-Delay: wait until the situation has modified sufficiently to allow a different level of engagement. Wait for conditions to meet identified triggers
Wildland Fire Size Up
Unit Location Vegetation fire size Fuel type Rate of spread Direction of spread Potential size Life or structure threat Actions taken (progressive hoselay) Identify divisions Additional resource request Establish IC
- BR133 is onscene at 1234 Main Street of an approximate 1 acre vegetation fire in medium fuels with a moderate rate of spread to the south-southeast with a potential for 5-10 acres. We currently have structures immediately threatened, BR133 is anchoring and starting a progressive hoselay along the hot flank which will be division Alpha. Start me a full Calfire Response including air and BR133 is establishing Main IC

Resource availability
On high or red flag days the company officer can…
- limit outside activities
- defer routine vehicle/equipment maintenance
- pay attention to hydration and fatigue factors
2 slope aspects that have higher fuel temps

Fire attack strategies
Direct
Indirect
Parallel
Combination of any of these
Fire attack tactics
Wet line
Hand line
Back burning
Burning out
Guidelines using wet line
More water needed for heavier fuels
Minimum 1.5” hose with 50 GPM nozzle for fast moving, high intensity, and/or threatening high-dollar exposures
Progressive hoselay require 1.5” hose
Never rely on hose line for FF safety
Burning out
Clean up a line with fire of residual fuel between control line and fire’s edge
