AD-H02 — ELECTRICAL WITNESS HOLD & MINE RETURN-TO-SERVICE GATE
Five source-original mine electrical witness holds check feeder identity, switching/earth/dead testing, VSD/UPS/DC remote feeds, flameproof/IS zone suitability and the dependencies of gas, fire, communications and ventilation systems.
ORIGINAL MINE ELECTRICAL WORK SCOPE
Use at mine-owned electrical witness and return-to-service stages. Complete MINE / AREA / LEVEL, WORK ORDER / MINE ZONE, DATE / SHIFT / PERMIT and CONTRACTOR SUPERVISOR.
FIVE MINE ELECTRICAL WITNESS GATES
1. Electrical asset and feeder positively identified against live mine single-line diagrams
2. Mine switching authority issues and records isolation, earthing and proof-of-dead
3. Backfeed, UPS, generator, battery, VSD and remote-start sources assessed
4. Flameproof or intrinsically safe apparatus selection matches declared mine zone
5. Gas/ventilation, communications and fire-system dependencies reviewed before impairment
COMPLETING REAL PRINTED WORD EVIDENCE
Complete five genuine HOLD TRIGGER / EVIDENCE GATE entries, recording REQUIRED EVIDENCE / VERIFICATION and RESULT / REFERENCE / WITNESS. Keep active mine single-line, switching schedule, isolation tests, protection proof and approvals.
MINE ELECTRICAL STOP-WORK AND SWITCHING
All applicable holds must PASS with dated work order and corrected defects witnessed before a named mine authority may issue plant/area release. Contractor signatures are not release.
TECHNICAL PERMIT RESTRICTIONS AND EVIDENCE
Attach actual switching schedule, single-line revision, earthing/proof-of-dead, DC/UPS/VSD backfeed, IS/flameproof classification, calibrated tests and mine owner acceptance. This editable source Word documents authorised work but does not create electrical switching permission, modify safety logic or authorise re-energisation.
