🔍 Key Concepts

• Lockout/Tagout (LOTO) procedures for electrical safety • How to ensure equipment cannot be accidentally re-energized while work is in progress • The difference between simply switching off power and physically securing the power source

💭 Think About

• Which option most effectively prevents accidental or unauthorized re-energizing of the circuit while personnel are working? • Look for the choice that involves both disconnecting power and providing a visible warning/control measure for others. • Ask yourself which step would be required by a safety officer before allowing electricians to touch the equipment.

✅ Before You Answer

• Verify which choice includes a positive means of securing the power source so it cannot be closed unintentionally. • Check whether any option conflicts with normal safety practices (e.g., bypassing safety devices or relying only on a person standing watch). • Confirm which option matches standard lockout/tagout concepts: open, secure, and clearly mark the energy-isolating device.
