May 9, 2014 (San Diego) – Mylar balloons can make great Mother’s Day and graduation gifts, if they’re kept indoors or securely tied down, but they can also pose a safety hazard.  San Diego Gas & Electric (SDG&E) today urged customers to be aware of the dangers that can arise when Mylar balloons touch power lines.

The metallic coating on Mylar balloons is an excellent conductor of electricity. If a Mylar balloon touches a power line, it could cause a power outage in your neighborhood, and even an electrical fire.

SDG&E reminds all San Diegans:

·         Keep Mylar balloons indoors.

·         If you see a Mylar balloon at an outdoor gathering, make sure that it is securely tied down or attached to a weight.

·         When disposing of a Mylar balloon, make sure to puncture it in several places.  Partially-inflated Mylar balloons can easily become airborne.

·         If a Mylar balloon, kite or any object becomes entangled in an overhead power line, call 9-1-1 or SDG&E at 800-411-7343.  Do not try to remove it yourself.

For more information on safety, please visit SDG&E’s website at or call 800-411-SDGE (7343).
