Abstract
A safety sign/barrier functions as a safety sign and as an access control barrier. The sign/barrier has an expandable fence member, a support, and a message display surface. The fence member has a variable length between its proximal and distal ends and expands and contracts along the length. The support includes two portions each of which are connected to an end of the fence member. The support is adapted to maintain the barrier in an upright, stable orientation when the fence member is contracted. Another embodiment provides a sign including a display surface and an expandable fence member. The display surface is either parallel to or at an acute angle relative to the expandable fence member. Methods of controlling access with a sign including an expandable fence and displaying messages on an access control barrier are also provided.
