Chapter Test 11 (IFSTA 7th Edition) Exam With Verified Questions and Answers

Chapter Test 11 (IFSTA 7th Edition) Exam With Verified Questions and Answers Tactical ventilation is performed during fire attack to: (493) [4.3.11, 4.3.12] quickly extinguish a fully developed fire. help control the fire. limit the need for LDH hose streams. minimize personnel needed on scene. - answerhelp control the fire. Why is ventilation used during overhaul and loss control? (493) [4.3.11, 4.3.12] To help control the fire Remove soot and odors from valuable contents Evacuate smoke from structures after a fire has been extinguished Eliminate the need for respiratory protection - answerEvacuate smoke from structures after a fire has been extinguished When performing tactical ventilation, what action has the most impact on successful ventilation? (494) [4.3.11, 4.3.12] Removing fuel sources Exposure protection Activating sprinkler systems Controlling oxygen availability - answerControlling oxygen availability Which action may improve visibility inside structures so that interior crews can work more effectively? (494) [4.3.11, 4.3.12] Cooling the exterior of the building ©EXAM STUDY MATERIAL 8/9/2024 11:50 AM Exposure protection Controlling exhaust openings Increasing the number of personnel - answerControlling exhaust openings As a fire within a compartment consumes oxygen, the amount of unburned fuel in combustion products: (494) [4.3.11] may either increase or decrease. increases. stays the same. decreases. - answerincreases. Why should ventilation be immediately followed with exterior or interior fire attack to cool gases and surfaces in the fire room? (494) [4.3.11, 4.3.12] The ventilation crew is already in position to perform fire attack. The greater the time between ventilation and application of water, the greater the fire's growth. Ventilation will cause the fire to go into decay, making it easy to extinguish. Fire will enter ventilation-limited decay when water is applied. - answerThe greater the time between ventilation and application of water, the greater the fire's growth. What disrupts the ventilation strategy and causes the fire to grow? (494) [4.3.11] Activating sprinkler systems Changing to a transitional attack Removing items from the structure Breaking windows unnecessarily - answerBreaking windows unnecessarily Before interior attack, what action will reduce oxygen available to the fire? (495) [4.3.11] Directing hose streams on the exterior of the structure Closing exterior doors and windows Directing hose streams to the interior of the structure Opening exterior doors and windows - answerClosing exterior doors and windows What occurs when fresh air (oxygen) from ventilation is introduced into a room, causing gases to reignite and rapid fire development to occur? (495) [4.3.11, 4.3.12] ©EXAM STUDY MATERIAL 8/9/2024 11:50 AM Burst Flashover Decay Vaporization - answerFlashover The primary mode of heat transfer from one compartment to another in a structure fire is: (497) [4.3.11, 4.3.12] radiation. direct burning. convection. conduction. - answerconvection Water application to a fire compartment begins to transition the fire from: (498) [4.3.11, 4.3.12] the growth stage to the fully-develop
