When it comes to lifting operations near overhead power lines, safety must always come first. The UK’s Health and Safety Executive (HSE) provides clear guidance under GS6 – Avoiding danger from overhead power lines. This post summarizes the key precautions and best practices for engineers and site managers when planning or executing lifts near live electrical lines.
Understanding GS6
GS6 aims to help businesses avoid electrical hazards from overhead lines, which often carry voltages from 11kV to 400kV. Contact with these lines can be fatal. Lifting equipment, cranes, telehandlers, and even long poles or scaffolding can unintentionally breach safe clearances if the proper controls are not in place.
Key Safety Measures from GS6
Risk Assessment
Identify and map all overhead power lines in the work area.
Assess the potential for contact or arcing.
Planning and Controls
If possible, avoid working near power lines entirely.
Use goalposts, barriers, and warning signs to mark exclusion zones.
Maintain minimum approach distances, typically 9m for lines up to 132kV unless the network operator advises otherwise.
Lifting Procedure Adjustments
Use banksmen or signalers to guide operators.
Use lifting equipment with restricted height movement or proximity sensors.
Ensure operators are trained on overhead line hazards.
Communication with DNO
Contact the Distribution Network Operator (DNO) before any lifting near power lines.
Temporary disconnection or insulation may be possible depending on the project timeline.
Emergency Planning
All site workers should know what to do in case of contact, including staying inside vehicles until it’s confirmed safe to exit.
Visual Aids and Toolkits
Include site sketches and GS6-compliant goalpost setups in your lifting plan. Visuals help ensure all personnel understand the hazards and control measures.
