A stray helium balloon triggered a power outage and a small fire in the Louisburgh area last week, prompting a local councillor and ESB Networks to warn the public of the hidden dangers balloons pose to the electricity network.

Cllr Chris Maxwell , who is based in Louisburgh, explained that the incident happened when a helium-filled balloon drifted into overhead power lines and caused an explosion.

"Last week where there was a potential for a big fire. A fire did occur, and the electricity went out over it," Cllr Maxwell said. "It's a funny thing — a helium balloon came down on the three-phase wire, and it exploded, and it started a fire underneath the wire."

Cllr Maxwell said the situation could have been far more serious were it not for a passer-by who spotted the fire and raised the alarm.

"There was a man lucky enough — he was saving his turf, not far away from it — and he raised the alarm to avert a dangerous situation," he said. "It could have been a dangerous wildfire or not, but I'd just like to let the public be wary that if these balloons — kids' big helium-filled balloons — escape, and there was aluminium inside them or something else, just be aware that this could happen at any time."

Cllr Maxwell said the episode should serve as a reminder to parents and party-goers alike that balloons let loose into the sky do not simply disappear — they can travel considerable distances before coming down, often with little warning, on live electrical infrastructure.

ESB Networks has echoed the councillor's concerns, reminding the public of the risks helium balloons pose to the electricity network, particularly during the busy summer party season.

"While helium balloons are a popular choice for parties and events, they can have an impact on the electricity infrastructure and public safety," the energy company said.

According to ESB Networks, balloons that escape into the air can become entangled in overhead lines, leading to power outages and electrical hazards that affect homes, farms and businesses.

ESB Networks is urging the public to take the following precautions when using helium balloons:

"By working together, we can ensure the safety and reliability of our electricity network while enjoying the festivities of the summer season," ESB Networks said. "Thank you for your cooperation and understanding."

The Louisburgh incident is the latest reminder that even small, seemingly harmless items like party balloons can carry serious consequences once they leave the ground — a message both ESB Networks and local representatives are keen for the public to take on board this summer.
