Production Outage and Under Emergency Maintenance State
Production Outage
This state of a plant arises because of shortage of stocks or product change over or shift change over or machine change over time, etc. In such state the production is not extracted from the machine and appears to be idle for shorter duration. Such shorter duration also might be made use by the plant engineering & management for effective maintenance.
Under Emergency Maintenance State
If the machine fails unexpectedly, this will be referred to the plant engineer to repair and put it in use at the earliest. It cannot be predicted by anyone but might happen because of any reason such as erratic operation, unsafe conditions, failure of a machine member, environmental conditions, etc. This maintenance is also called as unplanned maintenance.
