Powerline safety markers
Powerline safety markers
When working near overhead powerlines, visibility is key to staying safe.
Installing powerline safety markers helps to enhance safety by alerting pilots, crane operators, and other personnel of potential electrical hazards.

What is a powerline safety marker?
A Powerline Safety Marker is a high-visibility device used to indicate the presence of overhead power lines, especially in areas where they might pose a hazard to aircraft, construction equipment, or tall vehicles.
They help enhance safety by alerting pilots, crane operators, and other personnel to avoid potential electrical hazards.
The RotamarkaTM powerline safety marker is a simple, cost-effective solution to make powerlines stand out and reduce the risk of accidental contact. This highly visible marker is perfect for both temporary and long-term installation.
Where should powerline safety markers be used?
In Victoria, powerline safety markers are recommended in areas where overhead powerlines pose a risk to activities such as low-level flying, construction, or farming operations. The markers enhance visibility and help prevent accidental contact.
According to Energy Safe Victoria’s No Go Zone guidelines, it’s essential to assess the proximity of work to powerlines and implement appropriate safety measures.
