Firefighter 1C Wildland Study Guide (Latest 2024/ 2025 Update) 100% Correct Questions and Verified Answers| Grade A Q: DRIP TORCH- What fuel it contains and how full they should be. Answer: Typically the fuel used is a mixture of *gasoline and diesel* with a ratio of *30% to 70%* respectively, although, the amounts may need to be adjusted according to fuel and weather conditions. Sometimes heavier oils are used to increase adhesion of the liquid fuel to the vegetation, and increase burn time and heat. -*3/4 FULL* Q: How long should a wildland firefighter be self-sufficient for? How many hours? Answer: A wildland firefighter should be able to be self-sufficient for *24-48 hours*, if needed. Q: What do you do with the materials of cutting line and how to construct a line. Answer: (Pg. 57-59 of 94) Toss burned material into the black Toss green material into the green. Line construction techniques: -Finish line: -Directly on fire's edge -*1 1/2 times wider than the fuel height* Techniques: - Clear fuels to mineral soil -Cut and remove roots -Not less than *18" wide* Q: What are the advantages of a direct attack? Answer: *Direct fire attack* is used for lighter fuels and for lower fire intensity—generally less than *4-foot* flame heights. *This strategy is preferred over indirect fire attack, because it allows direct and continuous observation of the fire.* *Parts of direct fire attack include:* -digging a fire line directly around the flames and -pulling burned fuel into the black; -using water; -smothering; and -removing an element from the fire triangle. Q: What are the advantage of an indirect attack? Answer: *Indirect fire attack* is used when you can't safely engage directly, because the fire rate of spread is significant. (Several factors can accelerate the fire rate and spread. Indirect attack takes advantage of *using natural and human-made barriers as fireline* and allows a choice of timing for backfiring. However, in general, flame height between *4-8 feet* and winds that are faster than 8 mph indicate a significant fire rate of spread. Q: 4 Types of Direct Attack Wild land Answer: 1) *Pincer*: 2 units simultaneous attacking the fire from both sides of the fire working towards the head. 2) *Flanking*: when more resources are applied on the hot flank of the fire. Resources will be working on both sides moving toward the head of the fire. Where the engine starts at an anchor point and essentially creates a wet line along one flank of the fire. The engine moves as fast as the fire is put out. 3) *Tandem*: when 2 units are deployed to one flank and work in tandem. The first unit knocks the fire down and the second unit mops up and extinguishes hot spots. 4) *Envelopment*: Involves suppression from many points on the fire. Q: Indirect Attack Methods (Wild land) Answer: 1) Using *natural fire breaks* to control fire. 2) *Topography*, fire behavior will dictate placement of man made fire line placement. 3) Firing out operations to *burn the unburned fuel* ahead of the fire. Q: What is the spacing when we are in hookline? Answer: *10 Feet* The entire line-up of firefighters is called a *"hook line"*. Make sure to leave at least *10'* between you and the next firefighter while working on and/or waling to your assignment. Q: How and where you should clamp your progressive hose lays Answer: *18" behind coupling* -Don't pinch hose -Lock clamp slowly -Release pressure
