Basic Safety Tips Near Overhead Power Lines
If your job involves working near overhead power lines, safety must always come first. Every year, workers in NSW are seriously injured — or worse — because they fail to follow basic safety protocols around powerlines. Fortunately, these types of incidents are almost always preventable with the right training and preparation.
In this article, we’ll walk through practical safety tips for working near overhead power lines, so you can reduce the risk of contact and keep your team safe on site.
Identify and assess all overhead hazards before starting work
Before any task begins, always conduct a thorough site assessment. One of the most common causes of incidents is failing to recognise the presence of overhead power lines altogether. Make sure powerlines are clearly identified on site plans and visually confirmed by your team during the pre-start process.
A site walkthrough should be mandatory before any machinery is operated. Look for low-hanging lines, poor visibility conditions, and obstacles that could push equipment too close to live assets. If you’re unsure about whether a line is live, assume it is until a qualified person confirms otherwise.
Know your exclusion zones and safe approach distances
In NSW, strict exclusion zones apply to anyone working near powerlines. These distances vary depending on voltage, type of equipment, and whether you’re considered a competent or authorised person. For example, for voltages up to 132kV, the general minimum safe distance is 3 metres for plant and equipment unless you have specific authorisation.
These zones exist for a reason — and even indirect contact can result in electrocution or arc flash. Proper training will teach you how to measure and maintain these distances in the field, including the use of visual markers, spotters, and signage.
Use trained spotters when operating plant
When operating cranes, EWPs, or other plant equipment near overhead powerlines, always use a trained safety observer. Spotters play a critical role in helping operators maintain safe distances and identify risks in real time. Make sure they’re positioned with a clear line of sight and know exactly what to watch for.
Spotters must be trained and familiar with the risks of working near live overhead assets. Untrained or distracted observers create a false sense of safety — and could contribute to the very accidents they’re meant to prevent.
Wear the right PPE and inspect it regularly
Personal protective equipment (PPE) is your last line of defence. High-visibility clothing, electrical-rated gloves, safety boots, and hard hats should be worn at all times when working near live infrastructure. But PPE is only effective if it’s in good condition.
Make sure you inspect your gear before each shift. Look for tears, damage, or worn insulation. Replace anything that doesn’t meet the standard. Even minor issues with PPE can lead to serious injury if something goes wrong.
Never assume power lines are insulated
One of the most dangerous misconceptions in the field is the belief that overhead lines are insulated or “safe to touch.” In reality, most powerlines in NSW are not insulated — and even those that are may not offer full protection under fault conditions.
Always treat every power line as live. Don’t take shortcuts. If your work requires closer access, make sure the line is de-energised and that you have written confirmation from the relevant network authority.
Get the right training before you go near overhead power lines
No one should be working near powerlines without completing recognised safety training. Whether you’re a plant operator, tradesperson, or non-electrical worker, overhead powerlines awareness is a legal requirement for many roles — especially when live assets are nearby.
At IAC Safety Services, we offer overhead powerlines training through our nationally recognised crane and plant course. Contact us today to book your spot.
