Preventive maintenance (PM) has the following meanings:

  1. The care and servicing by personnel for the purpose of maintaining equipment and facilities in satisfactory operating condition by providing for systematic inspection, detection, and correction of incipient failures either before they occur or before they develop into major defects.
  2. Preventive maintenance tends to follow planned guidelines from time-to-time to prevent equipment and machineries breakdown (Olakotan, 2015).
  3. According to Bamiro, Nzediegwu, Oladejo, Rahaman and Adebayo (2011) , preventive maintenance is the work carried out on equipment in order to avoid its breakdown or malfunction. It is a regular and routine action taken on equipment in order to prevent its breakdown
  4. Maintenance, including tests, measurements, adjustments, parts replacement, and cleaning, performed specifically to prevent faults from occurring.

The primary goal of maintenance is to avoid or mitigate the consequences of failure of equipment. This may be by preventing the failure before it actually occurs which Planned Maintenance and Condition Based Maintenance help to achieve. It is designed to preserve and restore equipment reliability by replacing worn components before they actually fail. Preventive maintenance activities include partial or complete overhauls at specified periods, oil changes, lubrication, minor adjustments, and so on. In addition, workers can record equipment deterioration so they know to replace or repair worn parts before they cause system failure. The ideal preventive maintenance program would prevent all equipment failure before it occurs.[citation needed]

There is a controversy of sorts regarding the propriety of the usage “preventative.”[1][2][3]
