An anti-obstruction system for improved safety in the event a barrier becomes obstructed by objects or a person. The anti-obstruction system utilizes a double swing hinge and an emergency release stop to act as the stop for the barrier so that the barrier can only swing in one direction. The release stop may have a support member (e.g., coupled to a frame) and a stop member coupled together through the use of a cover. The stop member stops the door from swinging in two directions when the release stop is engaged and allows the door to swing past the stop member when it is disengaged. The release stop may be engaged and disengaged through the use of a release lock that has one or more projections that restrict movement between the support member, the stop member, and/or the cover when engaged, and allows for movement when disengaged.
