1). Isolation and Lock-Out Tag-Out (LOTO)
Before doing any electrical work, always disconnect the circuit from the power supply. Utilize the Lock-Out Tag-Out (LOTO) approach to avoid accidental energization. This ensures that no one may turn on the power supply while repair or inspection is underway.
2). Verification of De-Energization
After isolating the circuit, use an appropriate testing device, such as a voltage tester (or) multimeter to ensure that it is deenergized. Carefully test the instrument on an identified live source before & after verification to ensure it is functioning properly.
3). Use Personal Protective Equipment (PPE)
Wear appropriate PPE for electrical work, such as insulated gloves, safety shoes, flame-resistant clothing, face shields & helmet. Use additional safety gear such as arc flash suits when working at high voltages.
4). Ensure Proper Grounding & Short Circuiting
In high-voltage systems, after confirming de-energization, use grounding rods & short-circuiting devices to discharge any residual (or) induced voltage. This prevents inadvertent shock from capacitive (or) inductive effects.
5). Use Insulated Tools and Equipment
Always utilize insulated hand tools rated for the voltage level you’re working with. Avoid utilizing instruments that are broken, damp, or untested. Regular inspection and repair of tools & testing devices is critical for ensuring safety compliance.
6). Maintain safe Distances and Barriers
When working on live or nearby energized items, always maintain the minimum approach distance (MAD) required by safety rules. To keep unauthorized individuals out of the work area, use insulating mats, barriers & warning signs.
7). Awareness of Environmental Conditions
Avoid electrical operations in wet or humid conditions because moisture raises the danger of shock. Before beginning any project, make sure there is adequate lighting, a dry environment, and suitable ventilation.
8). Standard Operating Procedures
Always adhere to the organization’s SOPs & electrical safety requirements (such as IEC, IEEE, or NFPA 70E). Before starting work, do toolbox talks to ensure that everyone understands the method and associated dangers.
9). Emergency Preparedness
Prepare for emergencies by knowing where to find first aid kits, fire extinguishers & emergency exits. Employees should be taught in CPR & electrical fire safety. Please report any incidents or nearby collisions immediately.
