AD-TT03 — ELECTRICAL SHIFT CHANGE & WORKFACE LESSONS TALK
Six genuine electrical/instrumentation mine shift controls start with positive feeder identification against the mine live single-line diagram, followed by official switching/earthing, all backfeed/remote-start paths, classified-zone apparatus, critical alarms and protected trip settings.
MINE ELECTRICAL SOURCE WORK APPLICATION
Use at a change of shift before resuming permitted underground electrical, instrument and control-system tasks. Enter MINE / AREA / DATE / SHIFT and PERMIT / PRESENTER.
SIX GENUINE ELECTRICAL WORKFACE BRIEFING CONTROLS
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
6. Instrumentation calibration and trip-setting changes approved by mine engineering
COMPLETING ACTUAL PRINTED WORD FIELDS
Brief all six source points and record the mine feeder diagram revision, switching authority, isolation/earthing and proof-of-dead, UPS/VSD/DC secondary feeds, zone-rated apparatus, dependencies and instrument change permissions. Obtain attendance on the genuine 16-signature form.
MINE SWITCHING, GAS AND REMOTE-START STOP WORK
The original emergency withdrawal triggers include unidentified energisation, lost gas alarm, unsafe protection modification or a missing switching permit. A prior shift's switching instruction does not authorise automatic re-energisation.
ELECTRICAL PERMISSIONS AND TECHNICAL EVIDENCE
Keep mine single-line revision, appointed switching instructions, lockout/earth/test-before-touch, hazardous-area rating, UPS/DC/backfeed analysis and functional alarm/trip test results. The Word original is evidence only; mine electrical and protection owners control energisation, critical logic changes and return to service.
