OPS.8.2:4.1 - Recover what must remain available
Name the protected work, the event that can call the resource, and the condition that counts as ready. Readiness includes the capability, access, configuration and inputs needed for the next protected action. Moving a person back to a workstation may precede readiness if the person still needs a handover or must reconstruct the situation.
Distinguish two common requirements:
- Be ready by a known time, with no earlier call included in the selected protection.
- Be ready within a stated delay after a call that can arrive while auxiliary work is running.
A job that fits the first requirement may fail the second. Also retain the amount and duration of protected service needed after the return; a prompt start alone may not satisfy the commitment.
Separate capacity needed for this protection from capacity left over after it. An idle interval does not establish either amount. If several services rely on the same reserve, retain their relevant joint demand through OPS.10.1. OPS.12 supplies the human capability, fatigue, rest and relief conditions that the allocation must preserve.
