Preview Questions Maintenance Technician | Role Specific Skill

Question 1: During preventive maintenance of a heat exchanger, what is the most critical aspect to focus on to ensure efficiency?

Which action should you take?

Choose only one option

Cleaning of the tubes and checking for signs of fouling or corrosion

Ensuring proper insulation around the unit

Verifying that the temperature sensors are calibrated correctly

Checking the heat exchanger frame for misalignment

Question 2: When troubleshooting a control valve that is not responding, what is the first step to diagnose the problem?

Which action should you take?

Choose only one option

Check for a signal or power failure and inspect the actuator for proper movement

Clean the valve from debris or fouling before further inspection

Inspect the valve body for leaks and corrosion

Check if the valve stem is overextended or undercompressed

Question 3: How should a Maintenance Technician address a malfunctioning cooling tower fan in a chemical plant that is not starting up?

Which action should you take?

Choose only one option

Lubricate the bearings and check for excessive wear

Check for obstructions or debris in the fan blade path

Increase the voltage to the motor to improve startup

Check the motor and starter for electrical issues and verify control signals

Question 4: When installing a heat exchanger, why is it critical to follow specific alignment and support guidelines?

Which action should you take?

Choose only one option

To avoid using additional safety measures during installation

To allow easy disassembly for routine cleaning

To reduce the time needed for installation and decrease system complexity

To prevent undue stress on the system and ensure that seals and connections remain intact during operation

Question 5: What actions must be taken before beginning maintenance on equipment containing hazardous materials?

Which action should you take?

Choose only one option

Isolate the equipment from all energy sources, verify proper ventilation, and confirm the absence of hazardous materials

Only isolate the electrical sources and ignore potential chemical hazards

Ignore the materials in the equipment and focus on repairs

Start work immediately without isolating energy sources

Question 6: In troubleshooting a pneumatic actuator, what is the most common cause of slow response times?

Which action should you take?

Choose only one option

Insufficient actuator size or pressure rating

Overly tight packing around the actuator shaft

Improperly set valve positions or incorrect input signals

Leaks in the air supply line or the actuator seals
