AS-TT04 — REFUGE CHAMBER FAILURE RECOGNITION & WITHDRAWAL TOOLBOX TALK
The actual AS-TT04 underground refuge chamber failure-recognition toolbox talk begins with official restoration, then tests communications, emergency response equipment and life support. It teaches contractors to withdraw rather than accept an unprotected refuge system.
WHEN AND WHERE TO USE THIS SOURCE
Brief maintenance, inspection and rescue-support personnel before work on refuge chambers, escape routes or emergency services, and again after changed mine instructions, permits or shifts. Record MINE / AREA / DATE / SHIFT and PERMIT / PRESENTER with the actual affected district.
SIX GENUINE EMERGENCY BRIEFING CONTROLS
1. Mine emergency control signs restoration and updates maps/muster instructions
2. Witnessed communication, alarm and life-support functional test completed
3. Rescue equipment remains available and competent responders are briefed
4. Refuge seals, pressure integrity, emergency lighting and gas monitors inspected
5. Self-rescuer issue, condition and training interfaces verified with mine records
6. Before isolation, alternative escape/refuge capability approved for affected district
HOW TO COMPLETE THE ORIGINAL WORD FORM
Discuss the six genuine numbered source points in their original order, then enter crew names or access numbers and signatures on the 16 printed attendance lines. Identify who is responsible for alternate escape coverage and which mine official grants restoration.
CRITICAL STOP AND MINE RELEASE RULE
The original STOP / WITHDRAW / NOTIFY MINE CONTROL rule applies to a refuge out of service without alternate protection or a failed life-support test. Do not treat a completed briefing as authority to reopen an emergency system.
SOURCE SIGNATURES AND ACTUAL EVIDENCE
The genuine toolbox talk provides ATTENDANCE — 16 SIGNATURE LINES and NAME / EMPLOYEE OR ACCESS NO. plus SIGNATURE columns. Its stop rule is mandatory; crew attendance never gives permission to remove emergency protection.
