FIFA has banned the use of many items within its stadiums as the 2014 FIFA World Cup gets underway in Brazil.

Most of the bans are aimed at preserving public safety in each of Brazil’s 12 host cities. For example, FIFA prohibits the possession or use of any object that can be used to cause violence. Fans aren’t allowed to bring bottles, knives, bombs, umbrellas or any item that can be used to stab or clash into World Cup stadiums.

Other things are banned to promote a fan-friendly atmosphere for each soccer game. At the 2010 World Cup, the vuvuzela, a plastic horn based on a South African musical instrument, annoyed crowds to such an extent that FIFA banned it and the caxirola, a similar item made in Brazil, for this year’s event.

Flags and posters larger than a certain size are also prohibited, in order to prevent an obstructed view to the field of play. Items used to take pictures, such as iPads, cameras or laptops, are banned for much the same reason.

Fans also won’t be able to smoke cigarettes or bring food or drink of any kind from outside the stadium. Lighters, however, are acceptable.
