MWS EOC QUESTIONS AND ANSWERS GRADED A+

MWS EOC QUESTIONS AND ANSWERS GRADED A+ What is the main responsibility of the driver/operator during water supply operations? Ensure consistent and reliable delivery of water to the firefighting team. How should a low-pressure condition in the pump be addressed? Check for air leaks, clogged intakes, or improper valve settings and correct them. What is the function of a pressure relief valve on the pump? To protect the system from excessive pressure that could cause damage. What is the primary purpose of a primer on the pump? To create a vacuum that helps draft water into the pump. How should the tank vent system be maintained? Inspect for obstructions and ensure it allows proper air exchange during filling and draining. 2 What is the role of the intake relief valve during drafting? To prevent overloading the pump with high incoming water pressure. What safety step should be taken when connecting to a pressurized hydrant? Open the hydrant slowly to avoid sudden pressure surges. What is a critical task when transitioning from drafting to tank operations? Switch the pump intake source from the draft to the onboard tank without interrupting water flow. How should a portable pump be positioned when drafting from a shallow water source? Place the pump close to the water’s edge with the strainer fully submerged. What is the purpose of a pump panel gauge? To monitor pressure, water flow, and system performance during operations. How should the driver/operator handle steep grades during water transport? Use lower gears and controlled braking to maintain stability and control. 3 What is a common cause of cavitation in a pump? Inadequate water supply to meet the pump's demand. What should be done if the apparatus begins to overheat during prolonged operations? Reduce the workload and, if necessary, shut down the pump to cool the engine. What is the purpose of using a nurse tanker in water shuttle operations? To provide continuous water supply directly to the attack apparatus. How can tank capacity be maximized during transport? Fill the tank to its maximum level without overloading the vehicle’s weight limits. What should be checked before starting drafting operations? Ensure all connections are secure, the pump is primed, and the water source is adequate. How should valves be operated during fill or discharge operations? Open and close valves gradually to avoid water
