Preview Questions Maintenance Technician | Role Specific Skill

Question 1: What should be the protocol for handling electrical equipment during maintenance in a hazardous environment?

Which action should you take?

Choose only one option

Work on electrical equipment without isolating the power source if the area is dry

Ensure all power sources are isolated, use explosion-proof tools, and wear proper PPE

Ignore PPE and use any available tool for speed

Only check for visible damage without isolation

Question 2: When conducting electrical maintenance in a chemical plant, what is the most important step to ensure safety compliance?

Which action should you take?

Choose only one option

Assume that electrical equipment is safe if the switch is off

Only check the voltage with a tester before working on live equipment

Ignore electrical safety standards if the equipment is grounded

De-energize the equipment and verify zero energy before working on electrical components

Question 3: What is the most important factor when installing instrumentation on machinery?

Which action should you take?

Choose only one option

Installing without calibrating or testing the equipment post-installation

Ensuring the sensors are placed at the correct measurement points and that wiring is properly insulated

Ignoring placement to save installation time

Using incorrect sensor models for the application

Question 4: In troubleshooting valve leakage in a chemical process, what is the first step a technician should take?

Which action should you take?

Choose only one option

Verify the valve's sealing mechanism and check for wear or damage

Increase the pressure to force the valve to close properly

Tighten the valve body to seal the leak

Replace the valve immediately without inspection

Question 5: What method should be used to diagnose a system that is consuming more energy than expected?

Which action should you take?

Choose only one option

Increase system load to balance energy consumption

Run the system continuously to observe energy fluctuations

Ignore the system's energy consumption and focus on other parameters

Analyze the system for inefficiencies, leaks, and possible mechanical malfunctions affecting energy consumption

Question 6: What is the significance of checking the pressure and temperature readings during troubleshooting?

Which action should you take?

Choose only one option

They are secondary checks and should only be done if primary troubleshooting fails

These readings help identify abnormalities in the system, such as leaks or blockages

They provide only theoretical data and are not used in troubleshooting

Pressure and temperature are irrelevant for troubleshooting complex systems
