Unit 12 Quiz: Wildland Urban Interface | S-130 Firefighter Training (Online Component) 2008 v2

1. Safety concerns and hazards while working in the wildland/urban interface are
• different from hazards on a normal wildland fire.
  
  
2. Identify THREE key foundational principles to follow, especially during incidents in the wildland/urban interface.
• Establish good communications with all involved agencies
• Understand your safety is first priority
• Determine your place in the chain of command
  
  
3. Identify FOUR “Watch-Out!” situations that apply specifically to fighting fires in the wildland/urban interface.
• Poor roads
• Inadequate water supply
• Natural fuels 30 feet (9 m) or closer to structures
• Panic during evacuation
  
  
4. Structure defense adds a whole new dimension to wildland fire fighting. Match each wildland/urban interface “Watch-out!” with the MOST appropriate caution.
• Can be complicated by power outages → Inadequate water supply
• Can push flame angle closer fuels → Strong winds
• Requires mobility and flexibility in the fire fighting effort → Extreme fire behavior
• Don’t apply a straight water stream near it → Downed power lines
• Can be complicated by lack of training → Panic during an evacuation
  
  
5. Roads and traffic management can become a critical issue when fighting fires in the interface. Identify FOUR road and traffic related problems you are likely to encounter.
• Private roads and driveways with only one way in
• Steep roads that are poor barriers to a spreading fire
• Roads with washouts, washboards, and large potholes
• Fire vehicles exceeding the bridge weight limits
  
  
6. Identify TWO ways to reduce a structure’s vulnerability to ignition and limit potential fire spread.
• Check eaves, roof, roof vents, and decks for smoldering or flames
• Remove combustible furniture from decks and place them inside structure
  
  
7. Structure fires can be deadly, but there are tell-tale signs pointing to trouble. Identify THREE structure situations you should avoid at ALL times. 
• Bulging windows with an unventilated roof
• Smoked-over or blackened windows
• Roofs that are over 25 percent enflamed during windy conditions
  
  
8. In the wildland/urban interface, hazardous materials pose a threat to your safety because of their flammability or toxicity. Identify FOUR precautions to take when you suspect hazardous materials are present at an incident.  
• Mark off area with flagging material or other warning devices
• Post a lookout
• Keep your supervisor informed of hazards
• Avoid breathing toxic fumes
  
  
9. Extreme fire behavior has caused major losses of life and property in the interface. Identify THREE contributing factors to extreme fire behavior.
• Dry and plentiful fuels
• Unstable atmosphere
• Eye level wind speed greater than 15 miles per hour (24 km/hour)
  
  
10. For threatened structures in the wildland/urban interface, certain assessments have to be made. Match each assessment criteria with a PRIMARY factor it attempts to determine.
• Fire fighting tactics → Whether to attack directly, indirectly, or not at all
• Structure distribution  → What structures might be saved
• Estimated time the will hit → When to escape to safety zone
  
  
11. Match each tactic you may use in protecting structures in the interface with the proper description.
    
• Hopeless situation → Abandoning fire fighting efforts and retreating to safety zone
• Direct attack → Attacking the fire at the burning edge before it arrives
• Indirect attack → Controlling the fire with a fireline
  
  
12. There are three tactical modes for fires in the wildland/urban interface. Match each category with an appropriate tactic.
• Offensive mode → Fight the fire before it reaches the structure
• Combined mode → Hold the fire to reduce number of structures threatened
• Defensive mode → Keep the structure from burning
