When should fire pumps be tested?

• A. Daily by in-plant managers
• B. Monthly by maintenance staff
• C. Weekly by in-plant managers
• D. Quarterly by external contractor

Answer: (C)

Regular testing of fire pumps is essential to ensure the standby system will operate when needed. The weekly function test checks that the pump automatically starts when called and runs correctly, confirming the starting sequence, controller operation, and alarms are all working. On-site personnel are best suited for this task because they are familiar with the plant’s controls, can promptly record results, and can address any issues right away. This on-site weekly approach aligns with standard practice for keeping life-safety systems reliable.

Daily testing is too frequent and wear-inducing; monthly testing by maintenance staff may miss issues that a weekly check would catch; quarterly testing by an external contractor lacks the regularity and on-site oversight typical for these systems.
