Facility Operations & Maintenance Flashcards

Which maintenance strategy involves replacing components at fixed time intervals regardless of their condition?

Answer: Preventive maintenance

Preventive maintenance schedules component replacement at fixed intervals to prevent failures before they occur.

What is the primary purpose of a Building Management System (BMS) in a facility?

Answer: Monitor and control mechanical and electrical systems

A BMS centralizes monitoring and control of HVAC, lighting, fire safety, and other building systems.

A technician notices vibration in a pump during operation. Which diagnostic tool is best suited to analyze this issue?

Answer: Vibration analyzer

A vibration analyzer measures frequency and amplitude of vibrations to diagnose mechanical issues in rotating equipment.

What does 'Mean Time Between Failures' (MTBF) measure in facility equipment management?

Answer: Average operational time between successive failures

MTBF is the average time a system operates between failures, used to estimate equipment reliability.

In a data center environment, what is the recommended temperature range per ASHRAE guidelines for equipment intake air?

Answer: 64.4–80.6°F (18–27°C)

ASHRAE A1-class equipment intake air should be maintained between 64.4°F and 80.6°F (18–27°C).

Which fire suppression system is most appropriate for a server room to avoid water damage to equipment?

Answer: Clean agent (gaseous) suppression

Clean agent systems use inert or chemical gases to suppress fires without leaving residue or causing water damage to electronics.

What is a 'hot aisle/cold aisle' configuration designed to achieve in a data center?

Answer: Improve airflow management to reduce cooling costs

Hot aisle/cold aisle layout alternates rack orientations so exhaust air and cool intake air don't mix, improving cooling efficiency.
