Electrical substations present one of the highest-risk environments in general industry. The hazard profile extends well beyond typical facility electrical work due to high fault current, arc flash energy, induced voltage, and step and touch potential exposure. This article breaks down what is legally required under OSHA versus what is considered best practice under consensus standards such as NFPA 70E, ANSI, IEEE, and ISO. The focus is on training, qualification, voltage classifications, PPE, tools, rescue requirements, risk assessments, and controls.

The retraining trigger in OSHA’s lockout/tagout (LOTO) standard is often misunderstood. Many programs treat retraining as periodic or annual. That is not what the regulation requires. The obligation is event-driven, and the key word driving that obligation is “change.”

Occupational noise exposure assessment is one of the most misunderstood and inconsistently executed components of an effective safety program. Many organizations default to a single method—either blanket personal dosimetry or broad area surveys—without fully understanding the strengths, limitations, and regulatory intent behind each.
