DOD ARFF CDC QUESTIONS AND ANSWERS ALREADY PASSED

DOD ARFF CDC QUESTIONS AND ANSWERS ALREADY PASSED What are the two types of fire suppression agents commonly used in ARFF operations? Aqueous Film-Forming Foam (AFFF) and dry chemical agents. What is the primary consideration when positioning ARFF vehicles at an aircraft crash scene? Position the vehicles upwind and at a safe distance, ensuring access to the aircraft while maintaining safety. What are the key components of an ARFF vehicle’s fire suppression system? Water tank, foam tank, pump, hose lines, and nozzles. Why is foam used in ARFF operations? Foam helps to suppress fires by smothering the flames and preventing re-ignition, especially in fuel-based fires. What safety equipment should ARFF personnel wear during an emergency response? 2 Full personal protective equipment (PPE), including helmet, gloves, fire-resistant clothing, and self-contained breathing apparatus (SCBA). What is the primary role of the ARFF firefighter during a plane crash response? To rescue victims, extinguish fires, and prevent secondary hazards such as fuel leaks or explosions. What are the major hazards ARFF personnel should be aware of when approaching an aircraft crash scene? Explosions, toxic fumes, electrical hazards, and unstable wreckage. What is the purpose of a crash axe in ARFF operations? A crash axe is used to access the aircraft, cut through materials, and rescue trapped individuals. What is the recommended foam concentration for an aircraft fire? A foam concentration of 3-6% is typically used for Class B fires, depending on the type of foam and the severity of the fire. 3 What should ARFF personnel do if the aircraft has an onboard fire that’s inaccessible? Establish a fire suppression perimeter and wait for additional support while monitoring the situation. What is the first step when responding to a fire involving an aircraft in-flight? The first step is to assess the situation, determine the type of fire, and prepare the appropriate fire suppression strategy. How should ARFF crews prepare for a potential aircraft emergency on the ground? Conduct regular training, ensure equipment is ready and operational, and familiarize themselves with the layout of the airport and aircraft. How can ARFF personnel mitigate the risks of hazardous materials during an aircraft crash response? Identify hazardous materials, contain spills, and implement proper decontamination procedures. What is the importance of communication between ARFF units and the incident command during an emergency? 4 Communication ensures a coordinated response, safety, and effective management of resources at the scene. What is the primary function of a foam proportioning system on an ARFF vehicle? To mix foam concentrate with water in the correct ratio for effective fire suppression. What is the correct procedure when responding to a jet fuel fire? Use foam to suppress the fire, ensuring complete coverage of the fuel source, and avoid using water directly on burning jet fuel. How can ARFF personnel recognize and handle an aircraft’s
