In 3M terminology, which statement defines Preventive Maintenance?

• A. Actions intended to prevent or discover functional failure
• B. Actions taken to fix equipment after a failure
• C. Scheduling actions to reorganize maintenance
• D. Documentation of maintenance history

Answer: (A)

Preventive maintenance in 3M is a proactive set of actions designed to keep equipment operating by preventing failures or catching issues early before they cause problems. This includes routine inspections, lubrication, adjustments, cleaning, and component replacements that are scheduled to occur before a failure happens, with the goal of maintaining reliability and readiness. The idea is to do maintenance work to prevent downtime, not just to fix things after they break. The other options describe different concepts: fixing after a failure is corrective maintenance, scheduling actions to reorganize maintenance is planning or scheduling rather than performing maintenance, and documenting maintenance history is record-keeping rather than performing maintenance actions.
