Planning Work Near Powerlines

Planning Work Safely Around Powerlines

Effective planning is the most reliable way to prevent powerline-related accidents. Many serious incidents occur simply because overhead or underground powerlines were not identified early enough. By planning properly before work begins, risks can be reduced significantly.

Identify Powerlines Before Work Starts

The first and most critical step is to identify all overhead and underground powerlines on or near the worksite. This should always be done before any machinery, tools, or excavation work begins.

Walk the site carefully and look up for overhead cables, not just at eye level. In addition, use utility plans, site drawings, and online service searches to locate underground power cables. Never assume an area is safe simply because cables are not immediately visible.

Determine Safe Working Distances

If overhead powerlines are present, you must establish the minimum safe distance required. Safe distances vary depending on voltage and guidance from the local electricity network operator.

When in doubt, the safest approach is to treat all overhead lines as high voltage and maintain the greatest possible clearance. Greater distance always means lower risk.

Set Up Exclusion Zones

Once powerlines have been identified, clear exclusion zones must be established. These are designated areas that machinery, vehicles, and equipment must not enter.

Exclusion zones should be clearly marked using:

• Physical barriers or fencing
• Cones and warning signage
• Ground markings where appropriate

These controls help ensure that everyone on site is aware of the danger areas at all times.

Plan the Use of Tall Plant and Machinery

Tasks involving tall or long-reach equipment present a higher level of risk. Cranes, MEWPs, telehandlers, agricultural machinery, and tipper vehicles must be carefully planned so they do not pass beneath or close to overhead powerlines.

Routes should be planned in advance, and a trained spotter or banksman should be used to guide movements. This reduces the risk of accidental encroachment into exclusion zones.

Seek Expert Advice When Necessary

If work must take place close to powerlines and you are unsure about safe distances, do not guess. Contact the local electricity network operator for guidance.

They can provide technical advice and, where necessary, may arrange for lines to be temporarily isolated, re-routed, or made safe. Taking this step can prevent serious injury or fatal accidents.

Follow Safe Digging Practices

When carrying out excavation or groundwork, always follow safe digging procedures. Underground cables can be just as dangerous as overhead lines.

This includes:

• Using utility plans and cable avoidance tools
• Confirming cable locations before mechanical digging
• Hand-digging carefully near known services

Brief and Communicate with the Workforce

Finally, ensure that all workers are fully briefed before work begins. Clear communication is essential to prevent mistakes.

Everyone on site must understand:

• Where powerlines and cables are located
• The required safe working distances
• The procedures to follow if conditions change

Good planning, clear controls, and effective communication save lives.
