Good question, you will find a huge gap in reported events (EEA Safety alerts) vrs the anecdotal evidence that I hear around the traps as a member and chair of the EEA SSPG.

Common themes from anecdotal evidence and the EEA issued safety alerts:

1. Switching instruction integrity

Missing steps (earthing, isolation)
Inadequate checking despite multiple reviewers
Poor release request quality feeding bad instructions

2. Control discipline breakdown

Deviating from instructions without reissue
Continuing switching when uncertainty exists
Failure to stop when conditions change

3. Earthing errors (critical risk)

Earth left applied during livening
Incorrect earth placement
Failure to verify earth status before restoration

4. Isolation assurance failures

Incorrect isolation points on permits
Assumptions based on testing instead of isolation
Delays in isolating supply (fault scenarios)

5. System information / configuration risk

SCADA vs field mismatch
Labelling errors
Incomplete commissioning updates

6. Human factors

Distraction (permit error)
Handover gaps (NOC)
Over-reliance on process rather than verification
