Pumping and Aerial Questions and
Answers 100% Pass
What is the primary function of a fire pump?
✔✔ To provide a continuous flow of water under pressure for firefighting operations.
Why is it essential to prime the pump before drafting water?
✔✔ To remove air and establish a vacuum to draw water into the pump.
What is the purpose of using a relief valve on a fire pump?
✔✔ To protect the pump and discharge hoses from over-pressurization.
How is water flow measured during pump operations?
✔✔ By using flow meters to determine gallons per minute (GPM).
Why must fire apparatus operators know the pump's rated capacity?
✔✔ To ensure it can meet the demands of the firefighting operation.
1
,What is cavitation, and why is it harmful to fire pumps?
✔✔ Cavitation occurs when water supply is insufficient, causing damage to pump components.
What is the role of a pressure governor in pump operation?
✔✔ To maintain a consistent discharge pressure automatically.
Why is it critical to understand the layout of the pump panel?
✔✔ To operate controls efficiently and make quick adjustments during firefighting.
What should be checked during a pump test?
✔✔ Water flow, pressure stability, and overall pump performance.
Why is hose friction loss an important consideration in pumping operations?
✔✔ It affects the pressure required to deliver water effectively to the nozzle.
What is the purpose of an intake strainer when drafting water?
✔✔ To prevent debris from entering and damaging the pump.
2
,Why must operators monitor water tank levels during operations?
✔✔ To ensure an uninterrupted water supply and avoid running the pump dry.
What should be done if the pump overheats during operation?
✔✔ Circulate water through the pump or discharge excess water to cool it.
Why is it important to know the height of an aerial apparatus?
✔✔ To safely position it without hitting overhead obstacles.
What is the function of outriggers on aerial apparatus?
✔✔ To stabilize the apparatus and ensure safe ladder operations.
How should an aerial ladder be positioned at a rescue scene?
✔✔ As close to the rescue point as possible, ensuring stability and safety.
Why is the weight capacity of an aerial ladder critical?
✔✔ To avoid overloading and prevent structural failure.
3
, What is the purpose of a turntable on an aerial apparatus?
✔✔ To allow the aerial ladder or platform to rotate for optimal positioning.
Why must aerial operators understand wind conditions?
✔✔ High winds can affect the stability and safety of aerial operations.
What is the proper procedure for bedding an aerial ladder after use?
✔✔ Lower and align it carefully, ensuring all components are secured.
Why is regular maintenance of pumps and aerial apparatus essential?
✔✔ To ensure reliability, prevent failures, and extend equipment lifespan.
What is the function of a waterway on an aerial device?
✔✔ To deliver water to the elevated nozzle for firefighting.
Why is training on pump and aerial operations critical for operators?
✔✔ To ensure skillful and safe use during emergency scenarios.
