All MLB teams have implemented mandatory metal detection screening of all fans prior to entry at each MLB ballpark. Oriole Park at Camden Yards has walk-through magnetometers or hand-held metal detectors at each entrance in order to ensure a safe and fun environment for fans attending Orioles games.

Wallets, phones, keys, and other permitted objects can remain in pockets or a size-compliant bag during entry screening. Bags that do not meet size requirements will not be allowed into the ballpark. Fans without a bag can utilize one of several Express Lanes found at Gates A, C, F, or H to go through security.
