In order to seal a room from a fluid, particularly, a liquid, and, preferably, water flowing into the room or out of the room, a barricading device has a flap that is swivelable from a first position about an axis into a second position. The flap is pivoted by an actuator. The flap is held in the first position by a locking device, whereby actuation of an unlocking device connected with the locking device releases the flap for pivoting into the second position.
