Rules and Requirements for the Use of Helium Balloons & Tanks
Helium balloons are permitted at The Moscone Center, provided they are tethered and weighted.
Use of helium tanks to inflate balloons as part of an exhibit, activity, or display is permissible only if the tank is properly secured, per manufacturer instructions, and is not accessible by the public. Any balloons distributed must be tethered to a weight.
Please note that the Licensee is responsible for any labor or damage charges relating to loose balloons and their retrieval.
