, Page 2 of 92
A. Perform all mechanical repairs personally
B. Design new mechanical systems
C. Oversee and coordinate mechanical maintenance and repair work
D. Approve city budgets
Answer: C
Rationale: Supervisors plan, direct, and coordinate maintenance and repair work rather than
performing all repairs themselves.
2. Preventive maintenance programs are most effective when they:
A. Are performed only after breakdowns
B. Focus on emergency repairs
C. Are scheduled regularly based on manufacturer recommendations
D. Are optional for older equipment
Answer: C
Rationale: Preventive maintenance is most effective when performed on a consistent schedule
to reduce failures and extend equipment life.
3. Which of the following is a key function of predictive maintenance?
A. Waiting until equipment fails to perform repairs
B. Using data and monitoring to anticipate failures before they occur
2

C. Eliminating the need for maintenance logs
D. Reducing equipment inspection frequency
Answer: B
Rationale: Predictive maintenance relies on monitoring systems and performance metrics to
identify issues before they cause downtime.
4. When supervising a mechanical team, the first step in assigning work is to:
A. Allow mechanics to choose their tasks
B. Assess the priority and urgency of tasks
C. Perform the work personally to demonstrate
D. Ignore scheduling to maintain flexibility
Answer: B
Rationale: Prioritizing tasks ensures that critical maintenance and repair work is addressed
efficiently and safely.

Answer: B
Rationale: Hydronic systems use water to transfer heat to and from spaces via boilers, pumps,
and piping.
6. What is the purpose of a lockout/tagout procedure?
A. Increase production speed
B. Prevent accidental equipment startup during maintenance
C. Monitor employee attendance
D. Control HVAC temperature
Answer: B
Rationale: Lockout/tagout procedures protect workers from injury by ensuring machines are
de-energized before maintenance.
7. Which type of maintenance record is most important for tracking equipment lifespan?
A. Purchase receipts
B. Preventive and repair logs
C. Employee attendance records
D. Training certificates
Answer: B
