Barrier systems and associated methods, including vapor and/or fire barrier systems, are disclosed herein. One aspect of the invention is directed toward a barrier system that includes a barrier coupled to a spool, and a drive system. The barrier is positioned to be wound onto and off of the spool as the barrier moves between a deployed position and a retracted position by the drive assembly. The system further includes a clutch configured to resist movement of the barrier system unless directed by the drive system, and to release the barrier to allow manual egress when power to the drive system fails. The system further includes a latch configured to retain the barrier in a retracted position and to prevent the barrier from deploying when power fails and the clutch releases.
