AN-TT04 — COMMUNICATIONS FAILURE RECOGNITION & EMERGENCY WITHDRAWAL TALK
AN-TT04 is the six-point original underground communication, monitoring and automation failure-recognition talk. It starts with gas, ventilation and seismic sensors affected by network changes and ends with control-room witnessed alarm and rollback testing.
WHEN TO USE THIS UNDERGROUND ORIGINAL
Use before network cutovers, OT software changes, sensor tests or interrupted tracking and emergency communications. Record MINE / AREA / DATE / SHIFT and PERMIT / PRESENTER, identify the mine control-room operator and brief exposed crew.
SIX ACTUAL UNDERGROUND COMMUNICATION BRIEFING CONTROLS
1. Gas/ventilation or seismic sensors affected by network change identified
2. Work equipment and cable glands are compatible with underground hazardous zones
3. Alternative communications and muster verification tested before interruption
4. Cyber access privilege, portable media and service accounts authorised
5. Alarm integrity, remote start and system time synchronisation verified
6. Mine control-room operator witnesses end-to-end alarm and rollback tests
HOW TO COMPLETE THIS ORIGINAL WORD RECORD
Discuss six real controls in source order: gas/ventilation/seismic dependencies, hazardous-zone glands and devices, tested fallback calls and muster tracking, authorised cyber access and portable media, remote start/alarm time synchronisation, plus control-room witnessed rollback. Obtain the original sixteen crew attendance signatures.
CRITICAL STOP-WORK AND MINE RELEASE
STOP / WITHDRAW / NOTIFY MINE CONTROL for lost emergency calls, bypassed interlocks or incomplete tracking. Only a mine-appointed official releases the affected mine system or zone, not a contractor toolbox signature.
CONTROLLED WORD SINGLE AND COMPLETE FILE OPTIONS
The source-identical editable AN-TT04 Word file costs R12.95 and is included in the 371-form Underground Mining Checklist Package and 628-page Contractor H&S File. Owners of either collection should not buy it twice. Mine-issued OT permits, emergency communications plans, competent change approvals and formal mine release always govern use.
