Preview Questions Maintenance Technician | Role Specific Skill

Question 1: In preventive maintenance of heat exchangers, what is the main purpose of performing tube bundle cleaning?

Which action should you take?

Choose only one option

To inspect external pressure relief valves only

To replace worn-out seals in the tube bundle

To remove fouling and scale that reduces heat transfer efficiency

To check for refrigerant leaks in the system

Question 2: How should a technician approach troubleshooting a heat exchanger that is not performing efficiently?

Which action should you take?

Choose only one option

Ignore the issue and continue using the heat exchanger at reduced efficiency

Replace the entire heat exchanger without examining its condition

Check for fouling, corrosion, or flow issues in both the hot and cold sides of the exchanger

Focus only on the external temperature measurements

Question 3: How should a Maintenance Technician handle a situation where a safety device is malfunctioning during maintenance?

Which action should you take?

Choose only one option

Continue work while bypassing the safety device temporarily

Proceed with the maintenance without checking safety features

Skip the repair of the malfunctioning device if the task seems minor

Isolate the affected system, use temporary safety measures, and report the malfunction for immediate repair

Question 4: During preventive maintenance of chemical reactors, what should be the priority task to prevent safety incidents?

Which action should you take?

Choose only one option

Ignoring safety features and focusing only on efficiency improvements

Inspecting the reactor's pressure relief systems and ensuring all safety interlocks are functional

Replacing reactor components based on age rather than condition

Focusing solely on cleaning the reactor's internal components

Question 5: What should be done to ensure safety compliance when working near open flame or high-heat equipment in a chemical plant?

Which action should you take?

Choose only one option

Use regular PPE and skip other safety precautions as long as the heat source is distant

Isolate heat sources, ensure proper ventilation, and use flame-resistant PPE

Work as quickly as possible without isolating the heat source

Only focus on equipment repairs and ignore heat source precautions

Question 6: When troubleshooting motors that overheat, what is the first diagnostic step to identify the root cause?

Which action should you take?

Choose only one option

Replace the motor's fan to ensure proper cooling

Measure the motor's current and voltage to check for overload conditions

Check the lubrication levels and bearing wear

Inspect the motor casing for signs of physical damage
