Plant Maintenance Quiz

What is the primary objective of plant maintenance?

• To increase machine speed

• To prevent equipment breakdowns and ensure reliable operations

• To minimize production output

• To replace equipment frequently

Which of the following is an example of preventive maintenance?

• Waiting for equipment to fail before making repairs

• Regularly scheduled lubrication of machinery

• Performing repairs only when the machine stops working

• Replacing an engine after a breakdown

Predictive maintenance relies on which of the following to assess equipment condition?

• Historical repair records

• Random guesswork

• Real-time data and condition monitoring tools

• Frequent shutdowns for inspections

In Total Productive Maintenance (TPM), who is responsible for performing basic maintenance tasks such as cleaning and lubrication?

• Only specialized maintenance technicians

• Operators and maintenance personnel

• Only the plant manager

• External contractors

What is the main advantage of predictive maintenance over preventive maintenance?

• It is less costly to implement

• Maintenance is performed only when needed, based on equipment condition

• It requires no data or monitoring

• It focuses on emergency repairs only

Which of the following is a key performance indicator (KPI) used to measure maintenance effectiveness?

• Production rate

• Mean Time Between Failures (MTBF)

• Machine noise level

• Employee turnover rate

What is the main disadvantage of corrective maintenance?

• It requires complex monitoring systems

• It may lead to higher downtime and repair costs

• It ensures equipment is always in optimal condition

• It involves continuous inspections and data analysis

In a hydraulic system, what is the common cause of equipment failure?

• Overheating

• Fluid contamination

• Excessive vibration

• Lack of air supply

Which of the following is an example of a predictive maintenance technique?

• Visual inspection of machinery

• Monthly oil changes

• Vibration analysis to detect early signs of mechanical issues

• Cleaning equipment after use

What is the purpose of reliability-centered maintenance (RCM)?

• To focus only on emergency repairs

• To determine the most efficient maintenance strategy for each piece of equipment

• To replace equipment frequently regardless of condition

• To avoid all forms of maintenance except cleaning
