The present disclosure relates to a barrier system for shielding humans from harmful exposure to fire, smoke, noxious fumes, or contaminated air. Some embodiments provide a deployable barrier system that has a barrier retract assist system configured to assist a user in manually moving the barrier from the deployed position toward the retracted position with at least a portion of the barrier being rolled onto the barrel portion for egress past the barrier. The retract assist system can be positioned inside of the barrel portion.

A fire and/or smoke curtain includes a roller, a fire and smoke curtain, and a retaining mechanism. The mechanism comprising an end plate for holding an end of the roller, a brake disc attached to the end of the roller. A connector attaches to the brake disc, the connector having a hook or ring element attached to a release mechanism comprising a lock element secured to the end plate at a proximal end, having a stop at its distal end and provided with a hook element onto which the hook or ring element of the connector is fitted, sliding lock element adapted to slide along a fixed plate, from a secure position in which the sliding lock is adapted to hold the hook or ring, and a release position, in which the hook or ring is released, releasing the brake to allow rotation of the roller and deploy the curtain.
