A facility manager wants to reduce lighting energy costs without a capital investment. The BEST immediate action is to:
Answer: Implement an occupancy-based lighting schedule
Implementing a lighting schedule that turns off lights in unoccupied areas requires no capital outlay and yields immediate savings.
Which type of maintenance is performed based on equipment condition data rather than fixed time intervals?
Answer: Condition-based maintenance
Condition-based maintenance (CBM) uses real-time monitoring data to trigger maintenance only when equipment condition warrants it.
When sizing a backup generator for critical facility loads, which load type requires special consideration due to high inrush current?
Answer: Large motor starting loads
Electric motors draw 5–8 times their full-load current during starting, which must be accounted for in generator sizing.
A cooling tower's approach temperature is increasing over time. The most likely cause is:
Answer: Scale buildup on fill media reducing heat transfer
Scale deposits on cooling tower fill reduce heat transfer efficiency, causing the leaving water temperature to approach the wet-bulb temperature more slowly.
In reliability-centered maintenance (RCM), which failure mode characteristic determines whether preventive replacement is effective?
Answer: Whether there is a distinct age-related wear-out pattern
Time-based preventive replacement is only effective when a component shows a clear increasing failure rate with age (wear-out pattern).
What is the primary purpose of a facility's computerized maintenance management system (CMMS)?
Answer: To track, schedule, and document maintenance activities and asset history
A CMMS centralizes work orders, asset records, PM schedules, parts inventory, and maintenance history to improve maintenance planning.
Which piping system component is used to prevent water hammer in high-velocity liquid lines?
Answer: Surge arrestor or water hammer arrestor
Water hammer arrestors absorb hydraulic shock caused by sudden valve closure, protecting pipes and fittings from pressure surges.
