One of the first rules when dealing with electrical hazards is to assume that all wires, equipment, and devices are what?

• A. Energized
• B. De-energized
• C. Hazardous only if touched
• D. Insulated

Answer: (A)

In electrical safety, you treat all wires, equipment, and devices as if they could be live at any moment. This is because energy can be present even when nothing obvious indicates it: capacitors can hold a charge, backfeed from other circuits can occur, wiring can be damaged, or switch positions might not guarantee de-energization. Approaching work as if everything is energized forces you to follow proper isolation procedures, verify de-energization with tested equipment, and use appropriate PPE and insulated tools. The safest practice is to lock out and tag out the system, physically isolate power sources, and confirm there is no voltage before proceeding. This mindset protects against shocks, burns, and arc-flash events that can occur without obvious signs of energy.
