2019 Q38 — Fire Pump Auto Start and Shutdown

⚠️ DRAFT
Q38 — Fire Pump Auto Start and Shutdown 086 FPS-A1.05 (2.9)
Given:

• Firefighting activities are in progress
• Fire Water Header pressure had lowered to a MINIMUM of 80 psig and it is now slowly rising.

Which ONE of the following completes the statements below?

Fire Pump #1 _(1)_ is/are running.

After firefighting activities are complete, the running Fire Pump(s) can be shutdown LOCALLY _(2)_.

(1)(2)
A. (1) ONLY — (2) or REMOTELY
B. (1) ONLY — (2) ONLY
C. (1) and Fire Pump #2 — (2) or REMOTELY
D. (1) and Fire Pump #2 — (2) ONLY
▶ Show Answer & Explanation
✓ B. Correct. For Part 1, Fire Pump #1 starts when Fire Water Header pressure lowers to 85 psig. Fire Pump #2 will start when Fire Water Header pressure lowers to 75 psig (following a time delay). Consequently, ONLY Fire Pump #1 is running. For Part 2, After firefighting activities are complete, the running Fire Pump(s) can be shutdown LOCALLY ONLY.
✗ A. Incorrect but plausible. Part 1 is correct. For Part 2, since the fire water pumps can be started locally or remotely, the candidate could incorrectly conclude that the running Fire Pump(s) can be shutdown locally or remotely.
✗ C. Incorrect but plausible. For Part 1, the candidate could incorrectly conclude that BOTH Fire Water Pumps start when fire water header pressure falls below 85 psig.
✗ D. Incorrect but plausible. For Part 1, the candidate could incorrectly conclude that BOTH Fire Water Pumps start when fire water header pressure falls below 85 psig.
