S190 Task Sheet Study Guide | High-Score Study Material What are some of the purposes of the S-190 course? (there are 4) - answer - 1. To provide the student with wildland fire behavior knowledge applicable for safe and effective fire management activities (wildfires, prescribed fire, and fire use). 2. This course introduces students to characteristics and interactions of the wildland fire environment (fuels, weather, and topography) that affect wildland fire behavior for safety purposes. 3. The materials in this course are elements of the wildland fire behavior curriculum. 4. This is the first formal wildand fire behavior training course the students will receive. What are some of the objectives of the S-190 course? (there are 3) - answer - 1. Identify and discuss the three sides of the fire triangle. 2. Identify the environmental factors of fuels, weather, and topography that affect the start and spread of wildland fire. 3. Describe the contributing factors that indicate the potential for increased fire behavior that may compromise safety. Upon completion of this unit, students will be able to... - answer - 1. Define basic terminology used in wildland fire. 2. Identify the elements of the fire triangle. 3. Describe three methods of heat transfer. Name the 9 parts of a Wildland Fire - answer - 1. Point of Origin 2. Head of a fire 3. Flank of a fire 4. Rear of a fire 5. Fire Perimeter 6. Fingers of a fire 7. Pockets of a fire 8. Island 9. Spot fire The precise location where a competent ignition source came into contact with the material first ignited and sustained combustion occurred. - answer - Point of Origin The side of the fire having the fastest rate of spread. - answer - Head of a fire The part of a fire's perimeter that is roughly parallel to the main direction of spread. - answer - Flank of a fire - That portion of a fire spreading directly into the wind or down slope - That portion of a fire edge opposite the head. - Slowest spreading portion of a fire edge. - answer - Rear of a fire (Heel of a fire) The entire outer edge or boundary of a fire. - answer - Fire Perimeter The long, narrow extensions of a fire projecting from the main body - answer - Fingers of a fire Unburned indentations in the fire edge formed by fingers or slow burning areas. - answer - Pockets of a fire Area of unburned fuel inside the fire perimeter - answer - Island Fire ignited outside the perimeter of the main fire by a firebrand. - answer - Spot fire 1. Point of Origin 2. Head of a fire 3. Flank of a fire 4. Rear of a fire 5. Fire Perimeter 6. Fingers of a fire 7. Pockets of a fire 8. Island 9. Spot fire - answer - What are the different Fire Behavior terms? (there are 10) - answer - 1. Smoldering 2. Creeping Fire 3. Running Fire 4. Spotting 5. Torching 6. Crown Fire 7. Flare Up 8. Firewhirl 9. Backing Fire 10. Flaming Front Fire burning without flame and barely spreading - answer - Smoldering Fire burning with a low flame and spreading slowly - answer - Creeping Fire Behavior of a fire spreading rapidly with a well defined head. - answer - Running Fire Behavior of a fire producing sparks or embers that are carried by the wind and which start new fires beyond the zone of direct ignition by the main fire. - answer - Spotting The burning of the foliage of a single tree or a small group of trees, from the bottom up. - answer - Torching A fire that advances from top to top of trees or shrubs more or less independent of a surface fire. Crown fires are sometimes classed as running or dependent to distinguish the degree of independence from the surface fire. - answer - Crown Fire Any sudden acceleration in the rate of spread or intensification of the fire. Unlike blowup, a flare-up is of relatively short duration and does not change existing control plans. - answer - Flare Up Spinning vortex column of ascending hot air and gases rising from a fire and carrying aloft smoke, debris, and flame. Fire whirls range in size from less
