Preview Questions Maintenance Technician | Role Specific Skill

Question 1: What is the most common cause of incorrect calibration in temperature controllers used in chemical processing?

Which action should you take?

Choose only one option

The controller being set to the wrong unit of measurement (Celsius vs. Fahrenheit)

Incorrect sensor placement or wiring leading to inaccurate temperature readings

Frequent power surges affecting the controller's accuracy

The controller's display being set incorrectly for the process range

Question 2: When performing preventive maintenance on a pump in a chemical plant, which of the following should be checked first?

Which action should you take?

Choose only one option

Impeller condition and alignment

Only the motor voltage and current

The pump's noise level and vibration frequency

Lubricant level and quality

Question 3: In troubleshooting a hydraulic pump, what would you check if the system is not reaching the expected pressure?

Which action should you take?

Choose only one option

Focus solely on the pressure gauge reading without inspecting the system

Let the system operate for a few hours to observe any changes

Assume the hydraulic fluid is contaminated and replace it immediately

Inspect for air in the hydraulic lines, low fluid levels, or a malfunctioning pump relief valve

Question 4: What is the critical factor in ensuring safety compliance when performing maintenance on electrical equipment?

Which action should you take?

Choose only one option

Checking only the voltage settings without ensuring the system is isolated

Conducting maintenance while energized if tools are insulated

Ensuring proper isolation and verification through lockout/tagout (LOTO) procedures and grounding

Only wearing rubber gloves without isolating the electrical supply

Question 5: What is the first action when troubleshooting a sensor that is providing incorrect readings?

Which action should you take?

Choose only one option

Ignore the sensor's output as it may be due to external factors

Verify the sensor wiring, calibration, and power supply for potential issues

Continue to use the sensor and adjust for discrepancies

Immediately replace the sensor without further investigation

Question 6: What is the first step in the installation of a new centrifugal pump in a chemical plant?

Which action should you take?

Choose only one option

Begin installation immediately without checking the foundation or alignment

Verify alignment, foundation stability, and correct piping before starting the installation process

Skip alignment checks and assume the pump is properly aligned from the factory

Focus only on the electrical connections and ignore mechanical aspects
