Did you know that safe clearances are subject to change?
Safe clearance guidelines provide general rules for working near—or passing under—power lines, but you may not know that these clearance guidelines can be affected by many factors:
• Clearance heights are reduced when off major highways; power lines can hang as low as four metres from the ground.
• Temperature changes.
• Wind-induced swing.
• Buildings, landscaping, ground conditions (like snow pack) and spoil piles.
• The increasing size and height of farm equipment.
Always contact your local utility for help setting safe limits of approach and developing a safe work plan around power lines.
