Reactive Maintenance
Reactive maintenance is work performed in response to an equipment problem after the condition is reported or the asset has already failed.
What this term means in maintenance
Reactive maintenance is work performed in response to an equipment problem after the condition is reported or the asset has already failed.
What reactive maintenance means
Reactive maintenance begins after a defect, abnormal condition, or failure becomes visible. The work may be urgent, but not every reactive job is an emergency.
Examples include:
- Repairing a failed motor
- Responding to an oil leak
- Replacing a broken belt
- Correcting a defect reported by an operator
- Restoring a safety device after a fault
Reactive maintenance versus breakdown maintenance
Breakdown maintenance starts after an asset can no longer perform its required function. Reactive maintenance is broader and may begin while the equipment is still operating but requires attention.
Practical example
An operator reports abnormal noise from a gearbox. Maintenance inspects it, finds a loose coupling, and raises a corrective work order before complete failure. The work is reactive because it started after a problem was reported, but it is not yet breakdown maintenance.
When reactive maintenance is acceptable
Reactive work may be reasonable for low-risk defects, non-critical equipment, and conditions that cannot be economically predicted or prevented.
Common mistake
Treating all reactive work as unavoidable hides recurring failures, poor inspection coverage, and ineffective preventive maintenance. Teams should review repeated reactive jobs and identify where planning or prevention can reduce them.
How this term differs
Reactive Maintenance is work initiated in response to an unexpected problem rather than through an established plan. It is related to Breakdown Maintenance, Corrective Maintenance, and Preventive Maintenance, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.

Breakdown Maintenance
Breakdown maintenance is repair work performed after an asset has failed and can no longer perform its required function.
Corrective Maintenance
Corrective maintenance is work performed to restore an asset after a defect, abnormal condition, or failure has been identified.
Planned Maintenance
Planned maintenance is work whose scope, labor, parts, tools, safety requirements, and execution method are prepared before the job begins.
Glossary FAQs
- Is reactive maintenance always bad?
No. It can be appropriate for low-risk, non-critical defects that are difficult or uneconomic to prevent.
- Is reactive maintenance the same as breakdown maintenance?
No. Breakdown maintenance begins after functional failure. Reactive maintenance may begin after a defect is reported while the asset still operates.
- How can reactive maintenance be reduced?
Improve defect reporting, inspection, preventive maintenance, condition monitoring, planning, and repeat-failure analysis.
