Lockout and tagout is essential to prevent workplace electrical hazards. It includes applying locks to power sources after deenergizing and tagging deactivated controls. What is the primary purpose?

• A. To Prevent Unexpected Energization of Equipment
• B. To Improve Production
• C. To Reduce Noise
• D. To Train Workers

Answer: (A)

Lockout and tagout centers on controlling hazardous energy so equipment cannot be energized or started up unexpectedly while someone is working on it. The locks physically secure the energy source in the off position, preventing a machine from being re-energized, even if someone else tries to restore power. The tags add a clear warning that maintenance is in progress and that re-energizing must follow proper procedures. This protects workers from injuries caused by unexpected startup or released stored energy during servicing. While production, noise reduction, or training can be important in other contexts, they are not the primary goal of lockout and tagout—the main purpose is to prevent unexpected energization of equipment.
