Reactive Maintenance is a method of simply repairing assets i.e. equipment, components, etc. to their normal working condition after its failure or breakdown. Such maintenance strategy is also known as breakdown maintenance. Such type of maintenance strategy is only applied to equipment that requires low cost to replace or repair it and to equipment’s that are not so essential for functions or operations. This is because reactive maintenance does not involve any planning schedule. But it requires less money and time to wait for equipment’s failure rather than money and time required for regular maintenance of equipment to prevent it from failure.
Reactive Maintenance Types :
There are basically four different types if reactive maintenance strategy available nowadays as given below:
- Breakdown Maintenance –
Breakdown maintenance, as the name suggests, is a type of maintenance required when equipment completely breaks down simply to repair it to normal working condition. Such type of maintenance is only applied when particular equipment does not operate or is broken down, or failure occurred. Breakdown maintenance is generally an unplanned event but it can be planned event also. One has to wait to perform maintenance tasks until particular equipment ceases to perform due to breakdown or failure. Breakdown maintenance is usually required when equipment is not working and can be repaired to normal working condition. It should be a planned event rather than an unplanned event as unplanned events may lead to health and safety risks, costly downtime, cease in production, etc.
- Run-to-failure Maintenance –
Run-to-failure maintenance, as the name suggests, is a type of maintenance applied until equipment gets failed. In such type of maintenance, equipment is allowed to run until its failure. It is a type of planned maintenance applied in cases where equipment breaks down at unexpected time. It simply means doing no or zero preventive maintenance of asset and letting asset run until its breakdown or failure. It always includes a deliberate decision i.e. planned and careful decision regarding repairment of equipment without affecting production and quality.
- Corrective Maintenance –
Corrective maintenance, as the name suggests, is a type of maintenance strategy applied to identify and rectify the failure of equipment so that particular failed equipment can be repaired to its normal working condition. It either replace or repair asset or equipment after it fails. One of main advantages of corrective maintenance is that one can identify defects before it causes any type of problem and results in breakdown of equipment. During various maintenance procedures, faulty parts are seen and identified before any disruption occurred.
- Emergency Maintenance –
Emergency maintenance, as the name suggests, is a type of maintenance that is applied immediately when an asset or equipment breaks down or gets failed and leads to a greater risk of health and safety. This maintenance type is simply required to prevent property, profitability, production of organization. It is applied to urgent safety requirements that is needed to be addressed.
