Remedial and preventive maintenance

They are not in Kaplan or BPP because they are not mentioned in the Paper MA syllabus.

Remedial maintenance is a type of maintenance that is performed after a failure has occurred, with the aim of restoring the equipment to its normal operating condition. Preventative maintenance, on the other hand, is a type of maintenance that is performed before a failure occurs, with the aim of preventing the failure from happening in the first place. Preventative maintenance can include tasks such as regular inspections, cleaning, lubrication, and replacement of worn parts. Both types of maintenance have their advantages and disadvantages, and the choice between them will depend on factors such as the cost of maintenance, the criticality of the equipment, and the consequences of failure.
