HSG47 Training for High Voltage (HV) Underground Cable Avoidance

Working around High Voltage (HV) underground cables represents the single most critical and life threatening risk on any civil engineering or utility project. The extreme dangers of these services require a level of competency far beyond standard safe digging practices. The consequences of an HV cable strike are not just financial penalties; they are catastrophic, often leading to fatality or severe, life-altering injuries.

For contractors, groundworkers, and supervisors operating on or near power generation, transmission, or distribution infrastructure, compliance with HSG47 (Avoiding Danger from Underground Services) is the mandated minimum. We provide specialized, EUSR accredited training focused purely on HV environments to ensure your team is not just compliant, but genuinely competent.

The Extreme Danger of High Voltage Strikes

A standard utility strike is serious; an HV strike is deadly. Our training prepares your team for the unique and devastating risks involved:

Fatal Electric Shock
Arc Flash and Blast
System Shutdown

Direct contact with HV cables (typically 11kV and above) results in immediate electrocution.

The immense energy released during an HV strike creates an arc flash, which can cause severe, deep tissue burns from heat exceeding 35,000°F and generate an explosive blast that causes physical trauma.

Striking an HV service can cause widespread power outages across local grids, resulting in national level penalties and immense project liability.

What Our Specialized HV Course Covers

This training is not a general overview; it is an intensive program focused on best practice and advanced detection techniques specifically for high voltage zones. We cover the entire scope of the HSG47 “Three Basic Elements,” with an emphasis on the complexities of HV cable environments:

🟩 Advanced Planning: Identifying and interpreting detailed HV utility drawings, including substation plans and feeder routes. Understanding site specific hazards and HV safety documentation.
🟩 Emergency Response: Procedures for emergency isolation, immediate first aid for electric shock and burn injuries, and site management following an HV incident.
🟩 Specialist Location: Mastering advanced use of CAT and Genny (Cable Avoidance Tool and Signal Generator) in electrically noisy environments where signals are often misleading or saturated. Techniques for depth estimation and signal nulling.
🟩 Safe Excavation Protocols: Establishing and rigorously maintaining the Proving or Safe Dig Zone around marked HV services. Implementing isolation procedures and defining clear roles for ground penetrating radar (GPR) and manual excavation.
