What safety practice is used to prevent equipment from being energized?

• A. Lockout/Tagout
• B. Grounding
• C. Personal Protective Equipment
• D. Safe Start

Answer: (A)

The main idea is to prevent the machine from being energized by isolating its energy sources and blocking any re-energization during maintenance. Lockout/Tagout does this by shutting down the equipment, isolating electrical, mechanical, hydraulic, pneumatic, and other energy sources, and placing a lock on the energy-control device along with a tag that identifies the work and the worker responsible. The lock provides a physical barrier so the machine can’t be started, and the tag communicates that maintenance is in progress and who is in charge; only the authorized person who applied the lock may remove it. This directly prevents unexpected energization and protects workers from stored-energy and startup hazards. Grounding protects against shock but doesn’t stop equipment from being energized; personal protective equipment protects the worker without stopping energization; Safe Start focuses on safe startup but doesn’t ensure isolation during maintenance.
