When working on an electrical, fluid power, or mechanical system a ____ procedure should be performed to lock out the energy.

When working on an electrical, fluid power, or mechanical system a ____ procedure should be performed to lock out the energy.

• A. LOTO
• B. SOP
• C. JSA
• D. QA

Answer: (A)

Lockout/Tagout procedures are used whenever you work on electrical, fluid power, or mechanical systems to keep energy from accidentally starting or from releasing stored energy while you perform maintenance. The goal is to isolate and control all energy sources so the equipment cannot be energized during the work. The process typically involves identifying all energy sources, shutting the equipment down through normal controls, isolating those sources with a lock on the energy‑isolating device, applying a tag to warn others, and then verifying that the energy is truly off before any work begins. Stored energy is released or restrained as needed (such as bleeding a line or discharging capacitors), and you confirm zero energy before starting. Work proceeds only after the area is clear and all safety checks are complete, and locks are removed only by the person who placed them with proper re-energization steps followed. This specific energy-control step is what keeps workers safe. Other terms like SOP describe routine operating steps, JSA focuses on identifying hazards and controls before a job, and QA relates to product quality; none of these provide the targeted energy-isolation procedure used during service.
