Which best describes preventive maintenance?

• A. Perform scheduled maintenance to prevent failures
• B. Replace components only after failure
• C. Operate equipment until it fails
• D. Do nothing until there is a breakdown

Answer: (A)

Preventive maintenance is the proactive practice of performing planned care on equipment to prevent failures before they happen. It means doing maintenance tasks at scheduled intervals or based on data from monitoring the machine, such as lubricating moving parts, changing filters, inspecting for wear, or replacing components before a fault occurs. The goal is to catch issues early and keep equipment running smoothly, which reduces unexpected downtime and often lowers overall costs compared to letting a fault occur and then fixing it. The other approaches describe waiting until a problem appears or doing nothing at all, which leads to more frequent breakdowns and higher disruption.
