Construction sites are home to tipper lorries, loaders, scaffold poles and metal ladders, all of which conduct electricity. Every year accidents occur as a result of accidental contact with overhead power lines.

At higher voltages electricity may jump short distances meaning equipment does not have to touch a power line for anyone standing on the ground touching the equipment to be severely affected.

• Mark the location of overhead power lines and underground cables on your site map.
• Arrange access routes to the site to avoid crossing under or close to overhead power lines.
• Follow safety regulations when working close to underground cables.
• Put up visual and physical warning signs (signs, posts, etc.) where crossing under overhead power lines is unavoidable.
• Always appoint a banksman to help move machinery and keep them away
