Preview Questions Maintenance Technician | Role Specific Skill

Question 1: How should a technician approach troubleshooting a heat exchanger that is not performing efficiently?

Which action should you take?

Choose only one option

Replace the entire heat exchanger without examining its condition

Ignore the issue and continue using the heat exchanger at reduced efficiency

Check for fouling, corrosion, or flow issues in both the hot and cold sides of the exchanger

Focus only on the external temperature measurements

Question 2: In the preventive maintenance procedure for pneumatic systems, what is the first check to identify air loss or inefficiency?

Which action should you take?

Choose only one option

Inspecting air compressors, regulators, and lines for leaks or contamination

Adjusting the pressure settings to maximize output

Only checking the external air filters for dirt

Replacing the pneumatic cylinders without inspecting other parts

Question 3: What role do environmental conditions play in the calibration of field instruments in chemical plants?

Which action should you take?

Choose only one option

Environmental conditions have minimal impact on calibration as long as equipment is functioning

Environmental conditions such as humidity and temperature can significantly affect the accuracy of instrument calibration

Environmental conditions should be ignored as instruments are calibrated to work in any setting

Calibration should always be done in extreme conditions to ensure robustness

Question 4: How does the OSHA Hazard Communication Standard (HCS) impact the maintenance technician's responsibilities?

Which action should you take?

Choose only one option

Ensuring that proper labels, safety data sheets (SDS), and training are provided for hazardous chemicals being handled

Using chemicals without proper identification if it is part of a routine maintenance task

Ignoring labeling requirements as long as chemicals are stored in secure areas

Only checking labels for the most dangerous chemicals and ignoring minor hazards

Question 5: What is the primary purpose of zeroing a differential pressure transmitter before calibration?

Which action should you take?

Choose only one option

To increase the transmitter's output signal to maximum capacity

To ensure that the transmitter's electrical wiring is properly grounded

To clean the pressure ports before calibration

To ensure the transmitter's reading starts at the correct baseline pressure, removing any residual offsets

Question 6: When troubleshooting leakage in pipelines, which of the following is the most likely cause of pressure loss in the system?

Which action should you take?

Choose only one option

The pressure relief valve set too high, causing over-pressurization

A temporary issue with valve adjustments during operation

Normal operational expansion of pipes under heat

A crack or hole in the pipe, allowing fluid to escape
