Lifting operations near overhead power lines are extremely dangerous because cranes, jibs, and loads can contact or arc to energised conductors without touching them directly. Contact with high-voltage overhead lines is almost always fatal. Strict exclusion zones and planning controls must be in place before any crane operates near power lines. This talk covers the controls required for lifting safely near overhead electricity.
Key Hazards
Fatal electrocution from crane jib or load contacting overhead power lines
Arcing between the crane and conductors without direct contact at high voltages
Ground current injuring workers standing near the crane after a power line strike
Lifting equipment exceeding safe approach distances due to poor planning or wind
Control Measures
Identify all overhead power lines on the site plan and physically on site before any lift begins.
Contact the distribution network operator to confirm voltage, clearance requirements, and options.
Establish exclusion zones based on the voltage of the overhead line as specified in GS6 guidance.
Use goal posts, bunting, and warning signs to clearly mark the exclusion zone boundaries on site.
Fit crane height and radius limiters where the lift plan requires them to prevent zone breaches.
Brief the crane operator and all lifting team members on the power line locations and exclusion zones.
Request a line outage from the network operator if safe clearance distances cannot be maintained.
Ensure a banksman maintains visual contact between the crane jib and the power lines throughout.
Do not allow any part of the crane, load, or rigging to enter the exclusion zone at any time.
Emergency / Rescue
If the crane contacts an overhead power line, stay in the cab and do not touch the ground and crane simultaneously. Warn everyone to stay clear. If you must evacuate, jump clear without touching the crane and ground at once. Call 999.
Remember
Identify all overhead power lines and confirm voltages with the network operator before any lift
Establish exclusion zones based on the line voltage as specified in HSE GS6 guidance
Goal posts, bunting, and signs must clearly mark the exclusion zone boundaries on the ground
No part of the crane, load, or rigging may enter the exclusion zone at any time during lifting
If the crane contacts a power line, stay in the cab and warn everyone to stay well clear
