   ➤ DGMS Tech Circular 02 of 2010 outlines procedures for WRAC/HIRA.
3. Training & Supervision:
   Workers must be trained in safety, first aid, and hazard reporting.
   ➤ Ref: Mines Vocational Training Rules, 1966.
4. Safe Working Practices:
• Proper lighting & ventilation underground.
• Safe gradient & haul road width in opencast mines.
• Restricted entry in danger zones.
• No unauthorized persons in workings.
5. Electrical & Fire Safety:
   All equipment to be flameproof in gassy seams, regular insulation checks, and fire extinguishers installed in key areas.
6. Emergency Preparedness:
   Each mine must maintain an Emergency Control Room and conduct mock drills as per DGMS Circular 08 of 2019.
7. Reporting of Accidents & Near Misses:
• Immediate intimation to DGMS.
• Detailed accident report as per Form IV of Mines Rules 1955.
