Threat to Power Service from Mylar Balloons Cited in Silicon Valley Power Warning
Posted Date: 5/23/2013

SANTA CLARA, Calif. - May 23, 2013 – Some power outages that can cause serious problems for hospitals, manufacturing companies and residents can be avoided if people celebrating events like graduations simply hold onto their Mylar balloons, says Silicon Valley Power (SVP). The City of Santa Clara’s municipal electric utility says a number of electricity interruptions are caused each year when the metallic balloons strike power lines, particularly around spring and summer holidays.

“I would not want to be the person in the middle of a root canal or a restaurant owner serving a room full of diners when the power goes out for no good reason,” said Larry Owens, SVP manager of Customer Services. “It takes just one careless release of a Mylar balloon to have a serious impact on local residents, businesses and health care facilities.”

Power outages of even a short period of time can trigger emergency measures at hospitals and cost local employers thousands of dollars, not to mention endanger the public when traffic signals stop functioning.

“A power event on a manufacturing assembly line or during product testing can literally add up to a loss of hundreds of thousands of dollars,” said Owens.

“We seem to have more power incidents related to balloons around graduation time, so we want to remind everyone to keep balloons in control.” Owens added that releasing Mylar balloons is against the law and violators can, at a minimum, be cited and fined.
