Dead State

This state of plant is the result of where the machine is not needed for production for a given period of time. And the machine is not taken up for production therefore this time is generally said to be dead time. This is the most appropriate time for plant engineering and management to take up for maintenance such like preventive maintenance or scheduled maintenance. Generally the night times, Sundays or holidays or play days, etc. are considered to be the dead time of the machines as it shall not be operated during these times.

There shall be no production loss and the maintenance manager might plan and schedule the preventive maintenance throughout this time, however the planning and performing must not exceed the dead time otherwise which might disturb the production.
