Before pruning or picking, locate all power lines on the property. Do not touch or work on any tree that is touching or near power lines. Always keep 4m away from overhead power lines. Every line must be treated as live. You don't need to touch a line to be in danger; electricity can arc (jump) through the air to your equipment and to you.
2. Moving equipment around lines
When moving tall machinery, choose a route with adequate clearance. Lifting equipment should be in a lowered position. Know where the power lines are before raising the platforms of hydraladas, cherry pickers, EWPs and dump truck beds.
3. Training vines
Do not use wires to train vines along the same path as overhead power lines. A broken wire flicking upwards can come into contact with nearby lines.
4. Use a Powerco-approved contractor
If a tree is within 4m of the overhead lines you must use an approved contractor to have it trimmed. A list of approved contractors can be found here: www.powerco.co.nz/Safety/Tree-Trimming/
