AE-TT03 — REFRIGERATION SHIFT CHANGE & WORKFACE LESSONS TALK
Six genuine underground mechanical/refrigeration shift controls start with identifying actual connected fluids and energy sources, then asphyxiation/airflow risks, all-system isolation, load-approved lifting, guarded couplings and refrigerant recovery.
MINE REFRIGERATION SOURCE WORK APPLICATION
Use at each underground refrigeration, cooling or mechanical-service maintenance shift change or changed worksite. Record MINE / AREA / DATE / SHIFT and PERMIT / PRESENTER with the actual mine zone and plant work order.
SIX GENUINE MINE WORKFACE TOOLBOX CONTROLS
1. Plant tag, location and all connected fluids/pressure/energy sources identified
2. Cooling/refrigerant work checked for asphyxiation, leakage and ventilation consequences
3. Hydraulic, pneumatic, steam, water, mechanical and electrical isolation proved
4. Lifting routes and roof-support anchor loads approved by mine responsible person
5. Rotating guards, coupling alignment and vibration baseline inspected
6. Drains, relief devices and refrigerant recovery arrangements verified
HOW TO FILL IN THE ACTUAL WORD FIELDS
Brief all six source items in original sequence; check plant tag and system pressure, refrigerant and ventilation impacts, isolation locks, engineered rigging/support, shaft conveyance, rotating alignment and refrigeration drains/recovery. Capture the original 16 attendance signatures.
STOP-WORK, OXYGEN DISPLACEMENT AND MINE RELEASE
The printed withdrawal trigger requires STOP for refrigerant gas alarm, uncontrolled pressure, heat stress or uncertain load anchoring. A contractor shift briefing is not plant or mine-area release.
TECHNICAL EVIDENCE AND VENTILATION AUTHORITY
Record actual mine refrigerant classification, isolation permit, gas/oxygen test, ventilation baseline, temporary cooling and heat-stress arrangements, rigging approvals, refrigerant recovery, commissioned alarms and responsible mine official sign-off. The editable source file records controls already approved; it cannot override statutory mine ventilation or critical service management.
ONE SOURCE ORIGINAL OR FULL UNDERGROUND COLLECTION
This R12.95 AE-TT03 Word source is included in the 371-original Underground Mining Checklist Package and complete 628-page Contractor H&S File. Existing collection owners should avoid buying it twice. Mine ventilation, mechanical engineering and emergency officials must authorise affected equipment release.
