The House Rules of Olympic and Paralympic Venues were officially unveiled by the Beijing Organizing Committee for the Games of the XXIX Olympiad (BOCOG) during a press conference in the Beijing International Media Centre (BIMC) yesterday.
The house rules will play a pivotal rule in maintaining the safety of the Olympic venues as well as the comfort for those watching the Games.
There are 22 restricted items and behaviors listed, plus 4 prohibited items and behaviors.

The press conference on the launch ceremony of the House Rules of Olympic and Paralympic Venues. (PD online Photo/Zhenyu Li)Food and beverages in either hard or soft containers, musical instruments such as drums, horns and whistles, flags of non-participating members of the Olympics or Paralympics, unauthorized professional videotaping equipment, objects that could injure others such as long-handled umbrellas, camera tripods and sticks, and electronic equipment that could interfere with the electronic signals of the Games etc, will be restricted to bring into the venues.
The restrictions are virtually the same as for the Athens and Sydney Olympics.
What slightly different are some specific details in which the regulations would be administered, for example, according to Keying Huang, the deputy director of the BOCOG Volunteer Department, "Coins were restricted to bring into the Olympic venue in the 2004 Athens Games, but for the benefit of the spectators, those are not restricted in our Games."
The provisions may be interpreted slightly differently at individual venues.
Interested readers could call (+86 10) 12308 for more information on the regulations. BOCOG provides detailed information in multiple languages.
