Preview Questions Maintenance Technician | Role Specific Skill

Question 1: What is the first step in ensuring electrical safety compliance during maintenance activities in a chemical plant?

Which action should you take?

Choose only one option

Relying on verbal communication to ensure electrical isolation

Ignoring isolation procedures if the equipment is turned off

Conducting a lockout/tagout (LOTO) procedure to ensure all electrical power is safely isolated

Using a test light to check power without following isolation protocols

Question 2: What is the primary purpose of calibration in the maintenance of instrumentation equipment in chemical plants?

Which action should you take?

Choose only one option

To extend the operational life of the equipment without adjusting readings

To avoid the need for regular inspections of equipment

To ensure that the equipment is providing accurate and reliable readings according to industry standards

To reduce the number of maintenance tasks required for equipment

Question 3: What is the most critical step in performing preventive maintenance on control valves in a petrochemical plant?

Which action should you take?

Choose only one option

Only replacing seals to avoid leaks

Verifying the actuator's performance and checking for signs of wear and improper seating

Adjusting the valve's pressure settings to the highest allowable limit

Monitoring the control loop response without checking the valve mechanics

Question 4: In preventive maintenance for a heat exchanger, what should be done if there are signs of corrosion or fouling in the tubes?

Which action should you take?

Choose only one option

Continue normal operation and delay maintenance until performance deteriorates

Ignore minor corrosion signs if they are not immediately affecting performance

Clean and remove corrosion, inspect for structural damage, and consider re-coating if needed

Only clean the heat exchanger without addressing the corrosion

Question 5: In a centrifugal pump, if the discharge pressure is low but the pump is operating at the correct speed, what is the most likely cause of the issue?

Which action should you take?

Choose only one option

Excessive bearing wear causing friction

Misalignment of the pump shaft

A clogged impeller or suction line restriction

Low voltage supply to the pump motor

Question 6: When performing maintenance on equipment containing hazardous materials, what is the first step to ensure safety compliance?

Which action should you take?

Choose only one option

Checking the system's energy status visually without isolating the equipment

Using the equipment's manual alone without verifying isolation procedures

Lockout/tagout procedures must be implemented to prevent accidental energization

Ignoring the energy isolation if the equipment is powered off
