S-130 - Basic Wildland Firefighting; Exam Qs &As Origin The area where the fire started. It is also the point from which the fire spreads, depending on the fuels present and the effects of wind and slope. Head The part of a wildland fire with the greatest forward rate of spread (ROS). The head of a fire often burns intensely and may move with alarming speed. Some large fires may have multiple heads. Fingers long, narrow strips of fire that extend from the main body of a fire. They f...

The Black - correct answerArea already burned by a wildland fire. Also called Burn. Rate of Speed (ROS) - correct answerFire spread is simply the movement of the fire. 1 ft. (0.3 m)/minute = 1 chain/hour 10 ft. (3 m)/minute = 10 chains/hour Chain - correct answerA surveying term and equals 66 ft. Mop-Up - correct answerExtinguishing or removing burning material near control lines, felling snags, and trenching logs to prevent rolling after an area has burned, to make a fire safe, or to...

S-290 Unit 1: The Fire Environment Questions and Answers Already Passed What are the three components of the wildland fire environment? Weather, Topography, Fuels What are the three methods of heat transfer? Conduction, Convection, Radiation Conduction Direct transfer of heat from one molecule of matter to another. Example: Cast iron pan handle too hot to touch. (Wood is a poor conductor of heat) Convection The transfer of heat resulting from the motion of air or fluid. Example: Column of smo...

Basic concepts of wild land fire latest update with verified solutions origin -️️The origin is the area where the fire started. It is also the point from which the fire spreads, depending on the fuels present and the effects of wind and slope. When the fire is human-caused, you often find the origin next to a trail, road, or highway, but a lightning strike or campfire can result in a very inaccessible point of origin. Protect the area of origin for subsequent investigation of fire cause wh...

List the three methods of mass transport of firebrands - wind, convection In an unstable atmosphere - Smoke will continue to rise long as it remains warmer than the surrounding atmosphere & Air parcels both rise and sink. Describe how convection influences transport of firebrands - throws the fire brands straight up to allow them to travel further. the primary factors that affect rate of spread are - changes in fuel type, wind speed, and steepness of slope. Which of the following cha...
