During a service test, what is the required duration and pressure for the second step?

The correct answer indicates that during a service test, the second step requires a duration of 10 minutes at 200 psi. This is aligned with the standards outlined for performance testing of fire apparatus. Specifically, this second step typically tests the pump's ability to operate at an elevated pressure, which is crucial for ensuring that the pump can deliver adequate water supply under pressure during an emergency response.

The specified pressure of 200 psi is significant because it reflects standard operational pressures used in firefighting, allowing firefighters to assess whether the apparatus can maintain adequate flow rates while withstanding the pressure required for effective operation. By maintaining this pressure for 10 minutes, it simulates realistic conditions the apparatus may face during service, ensuring reliability and safety in actual firefighting situations.

The other options do not meet the established requirements set forth in testing protocols and regulations typically followed in the fire service. Instead, they either utilize incorrect pressures or durations that do not conform to standards established for testing fire apparatus performance. This reinforces the importance of adhering to prescribed testing criteria in order to maintain operational readiness and ensure safety.
