Powerline Perspective: Why Working Near Powerlines Requires More Than Just Keeping Your Distance
When it comes to working at height, few hazards are as unforgiving as overhead powerlines.
Many people assume that as long as a MEWP doesn’t physically touch a powerline, they are safe. Unfortunately, that’s not always the case. Electricity can behave in ways that aren’t immediately obvious, and a moment of complacency can have devastating consequences.
Whether you’re operating a MEWP, supervising a worksite, or planning a project near overhead services, understanding the risks associated with powerlines is essential.
Electricity Doesn’t Need Direct Contact
One of the most common misconceptions about powerlines is that danger only exists when direct contact is made.
In reality, high-voltage electricity can arc. This means electricity can bridge a gap through the air to a nearby conductive object, even when there is no physical contact.
The higher the voltage, the greater the potential for electricity to travel through the air. This is why maintaining safe approach distances is critical when operating a MEWP near overhead lines.
Understanding Minimum Approach Distances
Minimum Approach Distances (MAD) are designed to provide a safe buffer between people, equipment, and energised powerlines.
As a general guide:
- Up to 132 kV: Maintain at least 3 metres clearance
- Up to 275 kV: Maintain at least 4 metres clearance
- Up to 400 kV: Maintain at least 5 metres clearance
These distances are minimums and should never be treated as targets.
If the voltage is unknown, operators should always assume the highest level of risk and maintain the greatest possible clearance.
Always Assume Powerlines Are Live
One of the most important rules when working near electrical infrastructure is simple:
Always assume powerlines are energised unless the relevant authority has officially confirmed otherwise.
Making assumptions about whether a line is active, isolated, or abandoned can place workers at significant risk.
Even lines that appear inactive should be treated with the same level of caution as known live conductors.
Powerlines Aren’t Always Easy to Spot
Powerlines can be surprisingly difficult to identify in a busy work environment.
They may be:
- Hidden by trees and vegetation
- Obscured by buildings or structures
- Difficult to see in poor lighting conditions
- Positioned below platform level when working at height
Operators often focus on the immediate task at hand and may fail to notice hazards outside their direct line of sight.
Before elevating a MEWP, take time to look up, look around, and assess the entire working area. Hazard awareness should extend beyond the intended work location and include all potential movement of the machine, operator, tools, and materials.
Environmental Conditions Can Change Everything
Safe distances are not always static.
Wind can cause overhead powerlines to sway or sag, reducing the clearance between the line and the MEWP platform.
Environmental factors such as humidity and changing weather conditions can also increase the likelihood of electrical arcing.
What appears to be a safe distance at the beginning of a task may not remain safe throughout the day.
Continuous monitoring of environmental conditions is essential whenever work is being conducted near powerlines.
Planning Is Your Best Defence
If work near powerlines cannot be avoided, planning becomes critical.
A safe work plan should include:
- A formal risk assessment
- Identification of all overhead hazards
- Safe operating procedures
- Clear communication between personnel
- Designated responsibilities on site
- A dedicated spotter where required
The role of a spotter is particularly important when working in close proximity to overhead hazards. Their sole responsibility should be maintaining awareness of clearances and helping operators avoid unsafe situations.
What If Contact Occurs?
If a MEWP makes contact with a powerline, panic can make the situation worse.
The safest response is typically to remain in the platform and avoid touching any external structures.
Emergency services and the relevant utility authority should be contacted immediately, and operators should wait until the area has been confirmed safe before attempting to exit.
Every incident will have unique circumstances, which is why proper emergency procedures should form part of every site’s planning process.
Rubber Tyres and Outriggers Are Not Protection
A dangerous myth still exists on some worksites: that rubber tyres or outriggers provide protection from electrical current.
They do not.
Workers should never rely on tyres, stabilisers, or any component of a MEWP to protect them from electrical hazards.
The only reliable protection is maintaining safe distances, following safe operating procedures, and ensuring proper planning is in place before work begins.
Safety Starts Before You Leave the Ground
Powerline incidents are rarely caused by a single mistake.
More often, they result from a series of assumptions, overlooked hazards, or inadequate planning.
Taking a few extra minutes to assess the site, identify hazards, confirm clearances, and communicate with your team can prevent a life-changing incident.
When it comes to electricity, there are no shortcuts and no second chances.
Stay safe, stay smart.
