What is considered the most important rule of electrical safety?

• A. Think first
• B. Never touch live parts
• C. Wear insulated gloves
• D. Keep water away from electrical equipment

Answer: (A)

Never touch live parts is the most important rule because energized components can deliver a dangerous shock, burn, or arc flash in an instant. The safest practice is to ensure the circuit is de-energized and properly isolated before work, using lockout/tagout as needed. Thinking first is helpful, but it doesn't remove the hazard if power is still on. Wearing insulated gloves provides protection, but PPE alone isn’t a guarantee and cannot replace de-energizing. Keeping water away from electrical equipment helps reduce the risk of short circuits and shocks, but the universal rule remains avoiding contact with live parts.
