Preview Questions Maintenance Technician | Role Specific Skill

Question 1: What is the most effective way to ensure compliance with hazardous material handling regulations during maintenance?

Which action should you take?

Choose only one option

Handle hazardous materials based on previous experience without reviewing new SDS

Skip PPE if the chemicals appear safe based on their color or odor

Assume all chemicals behave the same way and use generic procedures

Review the Safety Data Sheets (SDS), use proper PPE, and follow containment and disposal procedures

Question 2: How should preventive maintenance procedures for gas detection systems be structured to ensure safety?

Which action should you take?

Choose only one option

Ignoring test frequencies and only maintaining the system during emergency events

Only replacing batteries in detectors without calibrating

Regular testing of sensors and calibration to ensure accurate readings and reliability

Replacing detectors on a fixed schedule without testing performance

Question 3: During the calibration of a flowmeter in a petrochemical plant, what is the most important factor to monitor to ensure accuracy?

Which action should you take?

Choose only one option

Only the power supply to the flowmeter and the system's pressure rating

The wiring and sensor connections without checking the actual flow rate

The external housing of the flowmeter for visible damage

The flow rate during calibration, ensuring it matches the meter's specifications

Question 4: 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 5: When testing flow meters in a chemical plant, what is the most critical parameter to verify?

Which action should you take?

Choose only one option

Ensure that the flow rate matches the factory specifications and calibration points

Focus only on the external condition of the flow meter

Check the flow meter casing for leaks without testing functionality

Only check for mechanical wear without considering flow accuracy

Question 6: 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
