Preview Questions Maintenance Technician | Role Specific Skill

Question 1: During preventive maintenance of chemical reactors, what should be the priority task to prevent safety incidents?

Which action should you take?

Choose only one option

Ignoring safety features and focusing only on efficiency improvements

Inspecting the reactor's pressure relief systems and ensuring all safety interlocks are functional

Replacing reactor components based on age rather than condition

Focusing solely on cleaning the reactor's internal components

Question 2: What is the most important step when setting up a lockout/tagout (LOTO) procedure during maintenance?

Which action should you take?

Choose only one option

Rely on verbal confirmation from operators and proceed with maintenance

Use only physical lockout without any documentation

Ensure that all energy sources are properly isolated and locked out to prevent accidental release

Skip the tagout if the equipment can be stopped manually

Question 3: What is the proper procedure for ensuring safety compliance when dealing with equipment under pressure in a chemical plant?

Which action should you take?

Choose only one option

Assume that pressure is low if the system has not been operated for a while

Verify that all isolation valves are closed, and depressurize the system before working on the equipment

Skip depressurizing the system if the pressure reading seems low

Only check the pressure gauges to verify safe pressure levels

Question 4: When performing calibration on a pH sensor in a reactor system, which of the following should be used to verify the sensor's accuracy?

Which action should you take?

Choose only one option

Standardized pH buffer solutions at multiple points across the pH range

Manufacturer-supplied chemicals and test kits to measure the electrode's response

A single pH calibration solution at the midpoint of the expected operating range

Only a visual inspection of the electrode for physical wear

Question 5: 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

Question 6: What is the significance of reviewing equipment manuals during the installation of a new machine in a chemical plant?

Which action should you take?

Choose only one option

Equipment manuals provide essential installation guidelines, alignment details, and safety procedures that ensure optimal setup

Manuals are not necessary if the equipment has been installed previously

Manuals should only be reviewed if the equipment fails to operate properly

Equipment manuals are only needed for troubleshooting and not during installation
