  • Personal Protective Equipment (PPE) – Mandatory use of helmets, gloves, safety shoes, and insulated gear for all technicians and visitors.
  • Medical Preparedness – First-aid kits, trained personnel, and tie-ups with nearby medical facilities for emergency response.
  • Ergonomic Practices – Proper lifting techniques, mechanical aids, and workstation design to reduce fatigue and injury.

 

Electrical & Mechanical Safety

  • Lockout-Tagout Procedures – Strict enforcement during rewinding, testing, and repair activities to prevent accidental energization.
  • Insulated Tools & Equipment – Use of certified tools and calibrated instruments to ensure safe handling of high-voltage systems.
  • Fire Safety – Fire extinguishers, alarms, and suppression systems installed and regularly inspected.
  • Emergency Drills – Routine fire and electrical hazard drills conducted to keep staff prepared.

 

Environmental Responsibility

  • Responsible Material Handling – Safe storage and disposal of varnishes, resins, oils, and insulation scraps.
  • Eco-Friendly Practices – Preference for high-class insulation materials with minimal environmental impact.
  • Waste Segregation – Mechanical, electrical, and chemical waste separated and disposed of responsibly.
