High voltage safety training teaches workers how to isolate, ground, and verify de-energized systems so switching errors, induced currents, and clearance violations do not turn routine work into fatal events.
High-voltage electrical systems do not fail gradually. When controls break down, they fail instantly, violently, and without margin for correction. Most serious electrical injuries and fatalities are not caused by defective equipment. They are caused by incorrect assumptions about isolation, grounding, approach distance, and system status.
This 6-hour, instructor-led program is designed to give electrical workers and safety leaders the judgment framework required to control Medium Voltage and High Voltage hazards under both normal and abnormal operating conditions. The course does not focus on theory alone. It focuses on the decisions that determine whether a system is truly safe to work on.
Participants learn how electrical energy behaves in distribution and substation environments, how hazards develop during switching and isolation, and why many incidents occur after equipment is believed to be de-energized.
The objective is not awareness. The objective is control.
High-voltage work exposes personnel to hazards that cannot be mitigated by experience alone. Arc flash, induced voltage, ground gradients, backfeed, and incorrect switching sequences continue to cause serious injuries in facilities where workers believed controls were in place.
This course addresses:
Why isolation errors are more dangerous than live contact
Why temporary grounding is a life-preserving control, not a procedural formality
Why switching to documentation failures creates fatal exposure
Why clearance violations escalate into multi-point fault paths
Why PPE cannot compensate for incorrect system status
Participants learn how to recognize when a system is electrically safe, when it is not, and how to prove the difference.
Our course is designed for frontline electrical workers responsible for Medium Voltage/High Voltage electrical systems, as well as supervisory and health and safety professionals who oversee high-voltage electrical safety work.
You will develop the knowledge and skills to properly assess the potential damage that electricity can cause to the human body and to understand the basic principles of safety under normal and abnormal conditions. You will also learn how to assist in determining the severity of potential exposure to Medium Voltage/High Voltage arc-flash hazards, plan safe work practices, and select appropriate personal protective equipment. You will also learn how NFPA 70E governs electrical hazards in distribution systems, as well as OSHA 1910.269.
During this High Voltage Safety Training course, you will learn to recognize and avoid electric shock in unsafe work areas. You will also learn the correct approach distances. Upon completion, you will have a better understanding of properly voltage-rated tools and the use of proper personal protection equipment. By educating workers on issues central to the safe performance of their everyday jobs, you can reduce and eliminate the risk of loss of life or serious injury in your workplace. Your safety and your coworkers' depend on it!
