As the Minnesota Vikings are set to kick off the NFL Preseason tonight at the Metrodome against the Houston Texans, they remind fans of a new safety policy regarding what you can bring into NFL stadiums - a policy which starts tonight.

The new safety policy, which was announced by the NFL earlier this year, encompases all games at each of the 32 stadiums in the league. The new policy sets guidelines on what fans can bring into the stadium.

The NFL and Minnesota Vikings encourage fans not to bring bags of any sort if at all possible, but if you must, they offer these rules.The new policy bans bags and purses, unless they're clear plastic or vinyl and no larger than 12" x 6" x 12". Approved clear, logoed bags are available through Minnesota Vikings merchandise outlets and nflshop.com. One suggestion includes one-gallon size clear freezer bags (or smaller).

The policy does allow small clutches, even if they aren't clear. Cameras and binoculars are allowed, but they also must be carried in a clear bag.Exceptions will be made for medically necessary items, and after proper inspection at the gate designated for this purpose.

Prohibited items include, but are not limited to: purses larger than a clutch bag, coolers, briefcases, backpacks, fanny packs, cinch bags, seat cushions, luggage of any kind, computer bags and camera bags or any bag larger than the permissible size.

The NFL says this policy change will provide a safer environment for fans and significantly speed up the entry process for fans into stadiums. Full details on this policy, including a frequently asked questions area are available at nfl.com/allclear.
