Common Misconceptions About Working Near Powerlines
Working near overhead powerlines carries serious risks, but many workers still operate under dangerous assumptions. These misconceptions can lead to life-threatening situations — especially in fast-paced or high-risk environments like construction sites, roadworks, or infrastructure projects. Whether you’re an electrician, machine operator, or civil contractor, you need to understand how powerlines behave and what safety measures apply.
In this article, we’ll break down some of the most common misconceptions about working near powerlines — and explain why getting the facts straight could save a life.
“Those powerlines are insulated, so we’re safe”
This is one of the most dangerous assumptions on a worksite. In most cases, overhead powerlines are not insulated — they’re bare, high-voltage conductors. Even if they appear to be covered, the material is often not designed for contact or to prevent electric shock. It may offer minimal weather protection but not personal safety.
Always treat every overhead line as live and uninsulated unless you’ve received written confirmation from the network authority. Never rely on visual inspection alone — it’s not enough to determine whether a line is safe to work near.
“We’re not touching the line, so there’s no danger”
You don’t need to make physical contact with a powerline to be injured. Electricity can arc — that is, jump across air — especially under high voltage. If a crane boom, EWP, or scaffold gets too close, the electrical current can travel through the air and strike the equipment.
That’s why exclusion zones and safe approach distances are strictly enforced. Even indirect proximity can lead to serious injury or death. Proper training teaches you how to measure and maintain those distances safely and consistently.
“The line must be de-energised if we’re working near powerlines”
Another common misconception is assuming a line is safe just because work is happening nearby. Unless you’ve received formal written notification from the relevant electricity distributor that the line is isolated and earthed, assume it is live. Never rely on word of mouth or assumption.
Before starting work near any electrical asset, confirm the line status with your supervisor or network provider and make sure all required permits and clearances are in place.
“I can rely on the spotter to keep us clear”
Spotters are a key safety control on high-risk worksites, but they’re not a substitute for proper training or personal responsibility. Operators must understand the limitations of their machinery, know how to measure boom height and swing radius, and stay aware of their surroundings.
Spotters support safe operation, but they can’t override poor decisions or replace the need for each worker to stay alert and informed. Everyone on site plays a role in preventing contact with powerlines.
“I’ve been doing this for years — I know what I’m doing”
Experience is valuable, but it doesn’t replace current training. Regulations, safety standards and network procedures change over time. What may have been considered safe ten years ago may no longer be compliant. Overconfidence leads to complacency — and in high-risk environments, complacency is dangerous.
Refresher training ensures that all workers stay up to date with the latest safety protocols, legal requirements, and best practices for avoiding powerline incidents.
