Emergency Maintenance is maintenance required when an asset or piece of equipment suffers an unexpected breakdown or change in condition that results in an immediate threat to health and safety.
Emergencies always happen without warning, so this type of maintenance cannot be scheduled, but having properly prepared and executed preventive maintenance program will eliminate almost all emergency maintenance.
This maintenance strategy is not a chosen strategy and Maintenance Teams do their best to avoid this. It often involves a high amount of unexpected working hours and is the most expensive type of maintenance.
