Electrical Safety & Standards

1. Electrical Safety:- Electrical Safety means following proper rules, procedures, and precautions to prevent electric shock, burns, fire, and equipment damage while working with or using electrical systems.
   • Common Electrical Hazards
     1. Electric shock (contact with live parts)
     2. Electrical burns & arc flash
     3. Fire due to short circuit or overload
     4. Equipment damage
     5. Explosion in hazardous area
   • Basic Electrical Safety Rules
     1. Always switch OFF & isolate supply before work
     2. Use proper PPE (insulated gloves, helmet, shoes)
     3. Ensure proper earthing (grounding)
     4. Never touch electrical equipment with wet hands
     5. Use correct-rated cables, fuses, and MCBs
     6. Avoid loose connections and exposed wires
     7. Follow Lockout–Tagout (LOTO) procedures in industry
2. Electrical Standards:- Electrical Standards are officially defined rules and technical guidelines that ensure electrical systems are: Safe, Reliable, Efficient, Uniform across regions and industries.
   • Major Electrical Safety Standards & Organizations
     1. IEC: Global standards for electrical, electronic, and related technologies.
     2. IEEE: Widely used technical standards for power systems, electronics, and safety.
     3. IS (India): Electrical safety codes followed in India (e.g., wiring, earthing).
     4. NEC (USA): Electrical installation safety code for buildings.
     5. OSHA: Workplace electrical safety regulations.
   • Importance of Electrical Safety Standards
     1. Protect human life
     2. Reduce accidents & downtime
     3. Improve system reliability
