In which scenario would emergency or breakdown maintenance be applicable?

Emergency or breakdown maintenance specifically pertains to situations where equipment is inoperative. This type of maintenance is necessary to address unexpected failures that halt operations and lead to equipment being non-functional. It aims to restore functionality as quickly as possible to minimize downtime and prevent disruption in the work process.

When equipment functions normally, or when it is due for scheduled maintenance or minor issues are found during preventive inspections, these situations are typically managed through routine maintenance processes rather than emergency maintenance. Such processes are aimed at preventing breakdowns and ensuring the smooth operation of equipment, as opposed to responding to an immediate failure. Thus, the applicability of emergency or breakdown maintenance clearly aligns with scenarios where equipment has ceased to operate.
