What is the term for maintenance performed before a service interruption occurs?

The term that describes maintenance performed before a service interruption occurs is preventative maintenance. This type of maintenance focuses on the proactive approach of taking steps to reduce the likelihood of unexpected failures and service interruptions. By conducting preventative maintenance, arborists and utility workers can assess the condition of trees and equipment, making necessary adjustments or repairs before any problems arise. This not only ensures the safety and reliability of the utility services but also helps in extending the lifespan of equipment and reducing long-term costs associated with emergency repairs.

While proactive maintenance and scheduled maintenance may seem similar, they do not specifically capture the focus on preventing issues before they happen, which is the essence of preventative maintenance. Deliberate maintenance, although a possible term, is less commonly used and does not have the same emphasis on the systematic planning and execution designed to prevent service disruptions.
