Stable section ID: S05-CON-014-SECTION-76 · 30 content blocks
Every controlled connection shall define its possible physical and operational states.
States may include:
- Disconnected.
- Presented.
- Coarsely aligned.
- Fully aligned.
- Temporarily captured.
- Mechanically engaged.
- Structurally locked.
- Utility-connected.
- Energized or pressurized.
- Inspected.
- Verified.
- Released for service.
- Isolated.
- Restricted.
- Released for removal.
- The conditions for entering and leaving each state shall be explicit.
Final locking shall provide positive, verifiable engagement appropriate to the consequence of unintended release. Partial engagement shall not appear indistinguishable from full locking.
Isolation shall control all relevant loads, stored energy, fluids, data commands, movement, environmental exposure, and hazardous conditions before maintenance or removal begins.
Safe release shall define:
- Required authorization.
- Temporary support.
- De-energization or depressurization.
- Unlocking sequence.
- Controlled withdrawal.
- Protection of adjacent assets.
- Post-removal configuration.
- Record updates.
Mechanical, visual, and digital indicators may be combined, but contradictory evidence shall prevent release for service until resolved.
