1. What is the first step in lockout/tagout?
A) Notify supervisor
B) Identify all energy sources
C) Apply locks
D) Test for zero energy
Answer: B
Rationale: Identify all energy sources before isolating and locking out.
2. Which PPE is required for confined space entry?
A) Hard hat only
B) Calibrated gas monitor and harness
C) Safety glasses
D) Steel-toe boots
Answer: B
Rationale: Confined spaces require atmospheric monitoring and retrieval
equipment.
,3. What is the primary cause of pump cavitation?
A) High discharge pressure
B) Low net positive suction head (NPSH)
C) Oversized motor
D) Closed discharge valve
Answer: B
Rationale: Cavitation occurs when NPSH available is less than NPSH required.
4. Which bearing type carries both radial and axial loads?
A) Ball bearing
B) Tapered roller bearing
C) Sleeve bearing
D) Thrust bearing only
Answer: B
Rationale: Tapered roller bearings handle combined radial and axial loads.
5. What does a vibration analysis detect?
A) Electrical faults
B) Mechanical degradation such as imbalance or misalignment
C) Flow rate
D) pH
Answer: B
2
,Rationale: Vibration signatures reveal bearing wear, imbalance, and misalignment.
6. What is the correct tool for measuring pump shaft runout?
A) Micrometer
B) Dial indicator
C) Caliper
D) Feeler gauge
Answer: B
Rationale: Dial indicators measure runout and alignment.
7. Which valve is best for throttling flow?
A) Gate valve
B) Globe valve
C) Check valve
D) Ball valve
Answer: B
Rationale: Globe valves provide precise throttling control.
8. What is the purpose of a check valve?
A) Regulate pressure
B) Prevent backflow
C) Throttle flow
3
, D) Isolate equipment
Answer: B
Rationale: Check valves allow flow in one direction only.
9. What is the first action when a motor trips on overload?
A) Reset immediately
B) Investigate cause before resetting
C) Increase overload setting
D) Replace motor
Answer: B
Rationale: Resetting without finding cause can damage equipment.
10. What does NPSH stand for?
A) Net Positive Suction Head
B) Net Positive Suction Head
C) Normal Pump Suction Height
D) Negative Pressure Suction Head
Answer: B
Rationale: NPSH is the total suction head at the pump impeller.
11. Which lubricant is typically used for high-temperature applications?
A) Mineral oil
