Non-PM refers to which type of maintenance?

• A. Regular routine checks
• B. Preventative Maintenance
• C. Accident-related repairs
• D. Non-preventative maintenance

Answer: (D)

Non-PM, or non-preventative maintenance, refers to maintenance activities that do not focus on preventing potential failures or issues but instead occur after a problem has already arisen. This type of maintenance is reactive rather than proactive. For example, non-preventative maintenance might include repairs that happen as a result of equipment breakdowns or malfunctions that were not anticipated or prevented through prior maintenance strategies.

Understanding this concept helps illustrate its role in a broader maintenance strategy, highlighting the importance of maintaining equipment to prevent issues before they arise. Non-preventative maintenance contrasts with preventative measures, which are designed to reduce the likelihood of equipment failure.
