Preview Questions Maintenance Technician | Role Specific Skill

Question 1: 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

Question 2: When testing a pressure relief valve to ensure it is functioning correctly, what is the key factor to monitor?

Which action should you take?

Choose only one option

The set pressure and the valve's ability to reseat without leakage after activation

The pressure at which the valve opens without considering reset characteristics

The actuator's electrical signal to open the valve

The valve's external appearance and physical condition

Question 3: What is the most effective way to monitor the condition of a centrifugal pump during preventive maintenance?

Which action should you take?

Choose only one option

By only inspecting the external components of the pump

By checking the vibration, temperature, and pressure levels at various operating conditions

By running the pump continuously during maintenance to observe performance

By replacing parts on a scheduled basis without checking their condition

Question 4: How should a technician approach the installation of a heat exchanger in a petrochemical plant?

Which action should you take?

Choose only one option

Install the heat exchanger without confirming the orientation or piping requirements

Install the unit quickly without verifying manufacturer's installation guidelines

Ensure correct orientation, secure mounting, and proper pipe connections to avoid leaks

Focus only on the external condition and neglect the internal connections

Question 5: What is the most likely cause of low flow rate in a chemical filtration system?

Which action should you take?

Choose only one option

Clogging of the filter media or pump wear leading to reduced efficiency

Over-pressurization of the filtration system causing safety shutoffs

Incorrect chemical composition or feed rate

A valve setting too high, restricting the flow rate

Question 6: How can safety compliance be ensured when handling and disposing of hazardous waste during routine maintenance?

Which action should you take?

Choose only one option

Follow the chemical plant's hazardous waste disposal procedures, including labeling and secure containment

Only use disposable containers for hazardous waste, ignoring labeling requirements

Dispose of waste by pouring it down the drain if it's not in large quantities

Keep waste in open containers in the work area until it can be dealt with
