OPS.8.2:5.1 - Practice during an operator’s reserve interval
An already-qualified operator has a 45-minute interval during which a call can require a return to protected service within five minutes. Once back, the operator and required equipment can sustain that service. A proposed practice exercise uses an independent training setup and can be stopped at short points.
The constructed timing assumptions are maximum durations under this arrangement:
| Return operation | Minutes |
|---|---|
| Detect the call | 1 |
| Reach a stopping point and leave the needed resumption note | 1 |
| Move to the protected workstation | 1 |
| Recover its current situation and prepare the next action | 2 |
| Total, with these operations serial and no additional waiting | 5 |
This exercise fits the stated response requirement. The calculation does not establish its learning value; its practice and feedback still need to serve the selected development question.
A live lesson with a 25-minute segment that cannot be left can exceed the entire five-minute allowance before transfer or restoration begins. Its fit within the 45-minute interval does not make it suitable for this anytime-call protection.
Now change the workstation’s restoration to five minutes. The former exercise gives 1 + 1 + 1 + 5 = 8 minutes and no longer preserves the response. Preparing a usable handover in advance might reduce restoration, but that is a changed arrangement whose time and burden must be included. Otherwise choose another activity or preserve readiness.
