Metal foil balloons and metallic ribbon conduct electricity, and when they become entangled in power lines or electrical equipment they can cause power outages for large numbers of customers. Some simple safety precautions can minimize the serious danger these decorations pose.

Never Use Metallic Ribbons
Foil/metallic string or ribbon, or other attachments that conduct electricity, should never be used with helium-filled latex or foil balloons, regardless of whether the balloons are for indoor or outdoor use.

Use Balloon Weights
Foil or mylar balloons should be attached to an anchor that is heavy enough to keep them from floating away. Never release helium-filled metal foil balloons into the air intentionally.

Never Group Foil Balloons
All foil balloons should be individually anchored. Clusters of balloons tied together stand a much greater chance of becoming entangled in power lines.
