Preview Questions Maintenance Technician | Role Specific Skill

Question 1: 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

Pressure and temperature are irrelevant for troubleshooting complex systems

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

They provide only theoretical data and are not used in troubleshooting

Question 2: 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 3: During machinery installation of tanks and mixers, what must be ensured regarding the mixing elements?

Which action should you take?

Choose only one option

Installing the system quickly without inspecting internal mechanisms

Only focusing on external mounting without considering the internal components

Proper alignment and secure mounting of agitators and blades to prevent uneven mixing and vibration

Ignoring the manufacturer's instructions for mixing speed settings

Question 4: What could be the cause if an air compressor in a petrochemical plant is not delivering the required pressure, even though it is running at normal speed?

Which action should you take?

Choose only one option

Low ambient temperature affecting motor performance

A leak in the discharge piping or valve system

Motor overload or electrical malfunction

Incorrect compressor oil level or improper lubrication

Question 5: When repairing pipelines in a hazardous area, what must a maintenance technician do to meet safety compliance?

Which action should you take?

Choose only one option

Follow de-energization procedures, perform atmospheric testing, and use appropriate PPE

Ignore the need for atmospheric testing if the area seems well-ventilated

Only check for leaks after completing repairs

Skip the PPE requirements if the pipeline is not in operation

Question 6: What is the most effective preventive maintenance action to prevent bearing failure in high-speed rotating equipment?

Which action should you take?

Choose only one option

Focusing on visual inspection without monitoring operating parameters

Regular lubrication, vibration monitoring, and periodic checks for wear and alignment

Only lubricating the bearings when noise or vibration becomes apparent

Checking bearings annually without routine lubrication
