Unit 10 Quiz: Suppression, Communication, and Mop-up | S-130 Firefighter Training (Online Component) 2008 v2

1. You’re trying to bring a wildland grass fire under control by removing one or more parts of the fire triangle. Identify THREE things you could remove from this scenario to break the fire triangle.
   
• Heat source
• Dry grass
• Oxygen
   
2. To control a fire, you need to break the fire triangle by removing one or more of the required elements. Select FOUR ways to remove heat energy from a fire.
• Cover with mineral soil
• Spray with water
• Apply retardant
• Expose hot materials to night air
   
3. Match each fire attack method with the situation you’ll employ it in.
• Used when avoiding an excessively long control line → Parallel attack
• When flame lengths exceed 8 feet (2.4 meters) → Indirect attack
• Moderately intense fires moving at a moderate rate of spread (ROS) → Flank attack
• Used when plenty of resources are available → Direct attack
   
4.  You and your crew arrive at a wildland fire scene and find flames 10 feet (3 m) high. The supervisor orders an indirect attack. Identify TWO characteristics of an indirect attack.
   
• Requires firefighters to build control lines
• Requires burnout or backfiring of fuels between control line and fire edge
  
  
5. Identify THREE commonly used applications for burning-out operations. Select one or more:
• Widen a control line
• Eliminate islands of unburned fuel
• Create escape routes and safety zones
  
  
6. Match each suppression technique with the correct description.
• Scratch line → Preliminary control line built to quickly check the fire’s spread
• Cup trench → Trench built on steep terrain to stop rolling debris
• Cold trailing → Feeling to detect fire
• extinguishing hot spots, lining live edges
• Backfiring  → Elimination of unburned fuel between a fire’s edge and a control line
• Hotspotting → Rapid attack on the hot-burning points of a fire’s edge
  
  
7.  The goal of burning out is to burn all fuels between the control line and the main fire in order to secure the control line and ensure firefighter safety. The activity used to fulfill this goal is called 
• blackening
  
  
8. Effective control lines all have
• an anchor point
  
  
9. Match each type of control line to the correct description.
• Control line on a slope below a fire → Underslung line
• Preliminary control line to quickly check the fire’s spread → Scratch line
• Portion of control line cleared completely to mineral soil → Fireline
• Temporary line made with water, foam, or retardants → Wet line
  
  
10. Identify THREE effective methods for control line construction. Select one or more:
    
• Throw all burned or charred material into the black
• Clear the line down to mineral soil
• Make the line wide enough to be effective, but no wider
  
  
11. You’ve just been told that an air tanker is going to drop retardant soon. How far away should you stand perpendicular from the drop?
• 200 feet (61 m)
  
  
12. Airdrops present opportunities and challenges. After an airdrop, you can often take advantage of the agent’s effects on the fire. Choose the set of words BEST completing the following sentence. After an airdrop, retardant can make the area 
• slick
  
  
13. Working safely around heavy equipment means staying visible and approaching the equipment from the right direction. Select THREE ways you can stay safe around heavy equipment.
• Approach mechanized equipment from the sides
• Post a lookout
• Wear proper personal protective equipment (PPE)
  
  
14. One of the most important safety practices to follow around mechanized equipment is to
• maintain effective communication between the equipment operator and the ground crews.
  
  
15. Identify FIVE communication methods firefighters can use with crew members. Select one or more:
• Whistles
• Runners
• Signal mirrors
• Signal flags
• Hand signals
  
  
16. Identify the THREE main classes of radios. Select one or more:
• Very high frequency (VHF)
• Ultra high frequency (UHF)
• Low-band
  
  
17. Very high frequency (VHF) is the type of radio class employed MOST often in wildland fire operations.
    
    
18. Very high frequency (VHF) is the type of radio class employed MOST often in wildland fire operations.
    
    
19. Use clear text terms when you are transmitting radio messages on large-scale operations. Match each example of an agency-specific radio code with an appropriate clear text equivalent.
• Pumper → Engine
• Wheeled tank vehicle → Water tender
• Tanker → Air tanker
• Mobile water supply apparatus → Tender
  
  
20. Generally, you’ll get prompt action when you use your radio properly. Identify THREE procedures to follow when receiving and transmitting a radio message.
• Hold the radio 2 to 4 inches (5 to 10 cm) from your mouth when speaking
• Close the call with the proper identifier only if you initiated the call
• When calling, first transmit the station name or unit number of the other person
  
  
21. Identify THREE things a patrol should do while searching for a spot fire.
• Select two reference points in your assigned area
• Patrol areas at intervals determined by fuel’s threat
• Patrol the area in a pattern parallel to the fireline
  
  
22. Match each mop-up situation to the appropriate action.
• Log on a slope → Turn to lie with the slope
• Snag burning at the top → Fell into the black
• Testing for heat    → Bare back of hand close, but not touching
• All smoldering material → Extinguished within a specified distance of the control line
• Snag burning at base → Peel off loose bark
• Hot material on a slope → Trench on downhill side
