Hold on to those balloons during celebrations, PSE&G warns.

With graduation season upon us, PSE&G issued a warning to customers about drones, kites and balloons. The utility says any of these objects can become entangled in overhead electric equipment and cause a host of problems.

The company says Mylar (or foil) balloons can cause power outages if they come into contact with power lines. PSE&G says the average number of balloons coming into contact with electric equipment nearly doubles in the month of June.

PSE&G says not to attempt to dislodge any object that is stuck in a power line. Instead, call PSE&G at 1-800-436-PSEG (7734).
