This section gives technicians a clear overview of the Lock‑Out/Tag‑Out Safe Work Procedures used when working on electrical systems. The full PDF provides the detailed steps, hazards, and responsibilities, while this page highlights what the procedure is about and why it matters when isolating energy sources on RedBlue job sites.
What This Procedure Covers
The LOTO SWP outlines the hazards, controls, and step‑by‑step process required to safely de‑energize, lock out, and verify electrical systems before performing any work. It’s designed to prevent electric shock, arc flash, stored‑energy release, and accidental re‑energization. Inside the PDF, you’ll find guidance on:
Common Hazards
Electric shock, electrical fires, stored energy release, pinch/crush hazards, cuts/scrapes, fall hazards, and flash burnsRequired Controls
Proper training, hazard identification, risk assessments, safe work area setup, and correct use of LOTO devicesSafety Equipment & Documentation
Electrical code book, LOTO procedures, breaker locks, cable locks, padlocks, hasps, plug lockouts, warning labelsProper Work Attire
No conductive jewelry, fire‑resistant clothing, and no synthetic materials during electrical workPPE Requirements
Non‑conductive eye protection, insulating gloves, steel‑toe footwear with rubber soles, hearing protectionLOTO Steps
Identifying energy sources, notifying affected personnel, shutting down equipment, isolating systems, dissipating stored energy, verifying isolation, completing work, and safely removing LOTO devicesVerification Requirements
Visual confirmation, testing circuits, and ensuring all energy is fully drained before work begins
Why It Matters
LOTO is one of the most critical safety procedures in electrical work. A single mistake can lead to severe injury or fatality. This Safe Work Procedure ensures every tech understands how to properly isolate electrical systems, prevent accidental energization, and follow the correct sequence of steps before starting work. It also reinforces the responsibilities of workers, supervisors, and the company in keeping job sites safe.
