AE-TT02 — COOLING MAINTENANCE WITHOUT CHANGING MINE VENTILATION TALK
Five authentic cooling-maintenance toolbox points protect underground mine air quantity and airflow while addressing refrigerant cylinders and leak detection, flammable gas/hot work, route-approved lifting, safe condensate discharge and alarm baseline checks.
MINE REFRIGERATION SOURCE WORK APPLICATION
Use before underground cooler servicing, refrigerant transfers, fan or duct control work where mine ventilation may be affected. Complete Mine / area, Contractor, Date / shift, Presenter, Work order / task and Risk assessment ref.
FIVE ORIGINAL MINE REFRIGERATION SAFETY POINTS
1. Refrigerant cylinders, leak detection, ventilation and ignition limits assessed for the mine zone.
2. Flammable refrigerants/gases and hot-work sources subject to mine-specific permits.
3. Lifts, rigging and transported heavy equipment approved for conveyances and route restrictions.
4. Drainage/condensate discharge does not create electrical or slip hazards or pollute mine water.
5. After recommissioning, verify mine ventilation and alarm functionality against the agreed pre-work baseline.
HOW TO FILL IN THE ACTUAL WORD FIELDS
Discuss the five original printed source controls; keep mine zone refrigerant gas monitoring and cylinder permits, hot-work segregation, approved heavy lift/shaft route, condensate route and matched pre/post mine ventilation plus alarms test. Sign the real attendance fields.
STOP-WORK, OXYGEN DISPLACEMENT AND MINE RELEASE
STOP for oxygen/gas alarm, changed airflow, refrigerant leak or no rescue readiness. The mine ventilation technical owner—not the cooling contractor—must accept restored airflow and alarm functionality.
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-TT02 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.
