AD-TT04 — ELECTRICAL FAILURE RECOGNITION & WITHDRAWAL TALK
Six original underground electrical failure-withdrawal toolbox checks cover UPS/generator/VSD backfeed and remote start, flameproof apparatus, gas/fire/communications dependencies, instrument trip changes, restored cable fire barriers and mine-owner functional release.
MINE ELECTRICAL SOURCE WORK APPLICATION
Use before mine electrical repair, instrumentation calibration or switching handover. Complete MINE / AREA / DATE / SHIFT and PERMIT / PRESENTER for the current underground mine feeder and host switching permit.
SIX GENUINE ELECTRICAL WORKFACE BRIEFING CONTROLS
1. Backfeed, UPS, generator, battery, VSD and remote-start sources assessed
2. Flameproof or intrinsically safe apparatus selection matches declared mine zone
3. Gas/ventilation, communications and fire-system dependencies reviewed before impairment
4. Instrumentation calibration and trip-setting changes approved by mine engineering
5. Cable penetrations, fire barriers and physical protection restored and recorded
6. Mine electrical owner witnesses functional tests and accepts return to service
COMPLETING ACTUAL PRINTED WORD FIELDS
Brief six real source items and verify dual supplies, hazardous zone electrical apparatus, life-critical monitoring, authorised protection settings, protected penetrations and witnessed functional tests. Record the original sixteen NAME / EMPLOYEE OR ACCESS NO. and SIGNATURE attendance lines.
MINE SWITCHING, GAS AND REMOTE-START STOP WORK
The printed STOP / WITHDRAW / NOTIFY MINE CONTROL clause applies to unknown feeds, invalid switching authority, disturbed protection or lost gas alarm. Never energise without named mine electrical owner approval.
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.
ONE SOURCE ORIGINAL OR COMPLETE MINE COLLECTION
This R12.95 AD-TT04 Word Single is included in the 371-original Underground Mining Checklist Package and complete 628-page Contractor H&S File. If you own either collection, avoid duplicate purchase. Mine-owned switchgear, hazardous-zone and safety-system permissions remain essential.
