WILDLAND URBAN INTERFACE

Structure Defense and SafetyStructure Defense and Safety

With the increased firefighting activities in the urban interface, wildland firefighter must become aware of a new fire environment.

Fire fighters tend to place themselves at greater risk when battling wildland fires in an effort to save homes.

REMEMBER…Safety of life is most important and must be adhered to by the use of the “fire Orders”, “Watch Out Situations”, and the use of “LCES”.

Safety While Protecting Safety While Protecting Structures From Wildland Fire Structures From Wildland Fire “ Structures exposed to wildland fires in

the urban interface can and should be considered as another fuel type. Sizeup and tactics should be based upon fuels, weather and topography, just as those criteria would be applied to a wildland fire”.

(Fireline Handbook Chapter4- Firefighter Safety)

Wildland/Urban Interface Wildland/Urban Interface ConsiderationsConsiderationsEngine crews are commonly utilized to

protect structures during wildfires.

Crew that are not familiar with operations in the wildland/urban interface should not be assigned structural protection duties.

Triage ?Triage ?

The process of evaluating and setting priorities for structures requiring protection from approaching wildfires.

What are factors that affect triage decisions?

Five Triage FactorsFive Triage Factors

Firefighter Safety Type and Structural Condition Surrounding Fuels Fire Behavior Available Resources

Reference: IRPG page 14-17

Triage CategoriesTriage Categories

1. Needing “LITTLE OR NO” protection for now.

2. Needing “PROTECTION” but “SAVEABLE”.

3. “INDEFENSIBLE”

Always Remember...Always Remember... Back your engine in. Keep one line for engine

protection. Keep 100 gallons in reserve. Continually re-assess L.C.E.S. Adhere to electrical power line

safety recommendations. Wear appropriate PPE for the

assignment. Don’t exceed your training!

Group Exercise ScenarioGroup Exercise Scenario

Two houses are adjacent, 50 feet apart. House #1 has wooden walls, a wood-shake roof, and is surrounded on three sides by brush. House # 2 has better clearance, grass around the house, and a composition shingle roof.

50’

House #1 House #2

Case 1: The fire is burning only the leaf litter, moving progres-sively past the two houses. You have a full 500 gallon tank of water and are the only engine available. What would you do?

House #1House #2

500 gal.

Group Exercise ScenarioGroup Exercise Scenario

Case 1 Solution: Control the fire at the first house it reaches and lead it past the second. Save both houses.

Case 2: The fire is burning the brush, hitting broad-side and threatening both houses at the same time. You have 250 gallons of water left and are the only engine available. House #1 will receive direct flame impingement; house #2 will receive only firebrands. What would you do?

House #1House #2

250 gal.

Group Exercise Scenario

Case 2 Solution : Forget house #1, it cannot be saved. Use your limited water to defend house #2. At least you will save one house. With only 50 feet between you must consider the exposure problems created by a fully burning structure (house #1). Now you are not only defending house #2 from a wildfire, but from a fully involved structure next door.

Case 3: As in Case 2, the fire is burning the brush and threatening both houses at the same time. This time you have a full tank of water, 500 gallons. You can protect house #1 as the fire hits it and in the process will significantly diminish the intensity at the head of the fire. A second engine will be there in 5 minutes. What would you do?

House #1House #2

500 gal.5 min. away

Group Exercise Scenario

Case 3 Solution: Take house #1 and do everything you can to save it. You might be able to simultaneously deploy a hose line to the second house and to have a firefighter spend at least some time on spot fires. House #2 will last until the other engine arrives. The second engine can handle house #2 and perhaps even give you a little help too. Save both houses.

Decision-making ExerciseDecision-making Exercise

You are sent into an area with four houses. Burning conditions are so severe that you can expect the standing live fuels to burn readily. You have a full tank of water, but no other resources will be available until well after the fire is past.

# 2 # 3

# 4

The most threatened house (#1) is in heavy fuels. It would require all your water to save, and the other houses would be involved by the time you could be free again.

Houses 3 and 4 are threatened only by firebrands on the roof. What would you do?

Houses 3 and 4 are threatened only by firebrands on the roof. What would you do?

500 gal.

Decision Making Exercise

Solution: First, consider taking on the most threatened house. You will save it, but with no time or water left you will lose the other three.

Next, consider taking on the second house. You will save it, and there is a good chance you will have time and water to deal with spot fires on the last two houses. You could save three.

Finally, consider taking on the easiest two houses. You can save them easily, but you will lose the other two.

The second alternative will buy you the most; three houses saved.
