- Keep balloons tethered at all times and attached to weights.
- Properly dispose of Mylar balloons by puncturing the balloon to release helium that otherwise could cause the balloon to float away.
- NEVER touch a power line. Do not attempt to retrieve a balloon or toy that is entangled in an overhead power line. For assistance, call ComEd at 1-800-EDISON-1 (800-334-7661).
- Always assume power lines are live and keep yourself, your belongings and anything you are carrying at least 10 feet away from power lines.
Warm weather brings outdoor parties for graduations, birthdays and weddings, but it also can lead to power outages when Mylar balloons from those festivities come into contact with power lines. Over a weekend in May, four Mylar balloons drifted into overhead electrical lines and caused power outages affecting approximately 6,000 customers.
