Definition
Preventive Maintenance refers to the regular and systematic inspection, cleaning, and repair of equipment and property to ensure they remain in optimal working condition. This type of maintenance aims to anticipate and prevent equipment failures before they occur, aiding in the smooth operation and extended lifespan of the equipment.
Examples
- HVAC Systems: Regularly changing air filters and inspecting heating and cooling units to ensure they are functioning properly.
- Automobile Maintenance: Regular oil changes, tire rotations, and brake inspections to ensure safe and efficient vehicle operation.
- Building Maintenance: Conducting routine inspections of structural elements, electrical systems, and plumbing to prevent deterioration and costly repairs.
- Manufacturing Equipment: Regular lubrication, part replacement, and performance checks on machinery to prevent breakdowns and maintain production efficiency.
Frequently Asked Questions
Q1: What is the main benefit of preventive maintenance?
A1: The primary benefit of preventive maintenance is the reduction in the likelihood of unexpected equipment failures, which can lead to costly emergency repairs or replacements and downtime.
Q2: How often should preventive maintenance be performed?
A2: The frequency of preventive maintenance depends on the equipment or property in question and the manufacturer’s recommendations. It typically ranges from daily to annually, based on usage and environmental conditions.
Q3: Can preventive maintenance be done in-house, or is it better to hire professionals?
A3: Preventive maintenance can be conducted in-house if the resources and expertise are available. However, for specialized equipment or in cases where safety is a concern, hiring professionals is advisable.
Q4: What are common preventive maintenance tasks?
A4: Common tasks include inspection, cleaning, lubrication, part replacements, software updates, and performance testing.
Q5: Is preventive maintenance cost-effective?
A5: Yes, preventive maintenance is generally more cost-effective in the long run as it helps avoid unplanned downtime and extends the lifespan of equipment, reducing the need for expensive repairs or replacements.
- Corrective Maintenance: Maintenance that is performed to repair faults that have already occurred.
- Predictive Maintenance: Using data analysis tools and techniques to predict when equipment failure might occur and performing maintenance just before that point.
- Reliability-Centered Maintenance (RCM): A process used to determine the maintenance requirements of physical assets in their operating context.
- Total Productive Maintenance (TPM): A system of maintaining and improving the integrity of production and quality systems through machines, equipment, processes, and employees’ efforts.

Fundamentals of Preventive Maintenance: Facilities Management Basics Quiz
### Why is preventive maintenance important?
- [x] To reduce the likelihood of unexpected equipment failures
- [ ] To increase immediate revenue
- [ ] To create redundancy in staffing
- [ ] To avoid hiring maintenance staff
> **Explanation:** Preventive maintenance is important because it helps to reduce the likelihood of unexpected equipment failures. By regularly inspecting and maintaining equipment, potential issues can be identified and resolved before they cause major problems.
### How does preventive maintenance differ from corrective maintenance?
- [ ] It is more expensive
- [x] It is done proactively before faults occur
- [ ] It involves replacing the entire equipment
- [ ] It is less reliable
> **Explanation:** Preventive maintenance differs from corrective maintenance in that it is performed proactively to prevent faults before they occur, while corrective maintenance is reactive and addresses faults after they have happened.
### What is a common task in preventive maintenance?
- [ ] Ignoring minor faults
- [x] Inspection and cleaning
- [ ] Letting equipment run to failure
- [ ] Disposing of machinery
> **Explanation:** A common task in preventive maintenance is the inspection and cleaning of equipment. This helps ensure that all components are functioning correctly and can prevent issues from developing.
### How does preventive maintenance extend the lifespan of equipment?
- [x] By addressing minor issues before they become major problems
- [ ] By ignoring less critical components
- [ ] Through allowing equipment to run without interruption
- [ ] By replacing equipment more frequently
> **Explanation:** Preventive maintenance extends the lifespan of equipment by addressing minor issues before they become major problems, thus reducing wear and tear and fostering optimal operation.
### What role does data play in preventive maintenance?
- [ ] It is not used
- [ ] Data slows down the process
- [x] Data helps track and plan maintenance schedules
- [ ] Data is only relevant for new machinery
> **Explanation:** Data is crucial in preventive maintenance as it helps track the condition of equipment and plan maintenance schedules effectively based on usage patterns and historical performance.
### Regulatory requirements for preventive maintenance are often established by which entities?
- [ ] Equipment operators
- [x] Manufacturers and industry standards
- [ ] Cleaning staff
- [ ] Random guidelines passed by any employee
> **Explanation:** Regulatory requirements for preventive maintenance are typically established by manufacturers who provide guidelines for the upkeep of their equipment and by industry standards to ensure safety and performance.
### Which of the following is a benefit of using professional services for preventive maintenance?
- [ ] Immediate cost savings
- [ ] Decreased equipment efficiency
- [x] Expertise and specialized skills
- [ ] Reduced need for documentation
> **Explanation:** Using professional services for preventive maintenance offers the benefit of expertise and specialized skills, ensuring the maintenance work meets high-quality standards and often extending the effective life of equipment.
### What is often included in a preventive maintenance checklist?
- [ ] Instructions to ignore minor noises
- [x] Scheduled inspections and tests
- [ ] Suggestions to replace equipment unnecessarily
- [ ] Steps to defer maintenance
> **Explanation:** A preventive maintenance checklist typically includes scheduled inspections and tests to ensure all components of the equipment are functioning properly and to identify any potential issues early.
### How does preventive maintenance affect production downtime?
- [x] It minimizes unexpected production downtime
- [ ] It increases the need for recalls
- [ ] It disrupts production frequently
- [ ] It holds up production permanently
> **Explanation:** Preventive maintenance minimizes unexpected production downtime by keeping equipment in good working condition and preventing sudden breakdowns that could halt production.
### What is a long-term financial benefit of preventive maintenance?
- [ ] Increasing initial capital expenditures
- [ ] Frequent replacement of machinery
- [x] Reducing costly, unexpected repairs
- [ ] Adding to yearly budget strain
> **Explanation:** A long-term financial benefit of preventive maintenance is reducing the costs associated with unexpected and major repairs, thus providing financial stability and predictability within a budget.
