Which action is part of post-run checks after shutting down the pump?

• A. Increase RPM.
• B. Immediately refill tank.
• C. Drain hoses.
• D. Observe gauges for stability and verify systems secured.

Answer: (D)

After you’ve shut the pump down, you want to confirm the system is in a safe, stable state. Observing the gauges for stability is essential because it shows whether pressure holds steady or if there’s a slow bleed, a potential leak, or an improperly seated valve after shutdown. Verifying that the systems are secured means making sure all valves, connections, and equipment are secured and no components are left loose or under unexpected stress. This combination confirms the pump isn’t harboring hidden issues and is safely secured for the next use.

The other actions don’t fit post-run checks. Increasing RPM is something you do while the pump is running, not after shutdown. Refill the tank immediately isn’t a standard post-run check and depends on fuel management procedures. Draining hoses isn’t a routine post-run check and could unnecessarily depressurize or delay securing the scene.
