ABSTRACT:
A safety sign includes a base, and a sign member supported on the base for allowing the sign member to be supported at a suitable height. The base includes a tube secured on a foot support for securing the sign member. A post has a lower portion slidably engaged in the tube for allowing the sign member to be adjusted relative to the base. A coupler is secured on top of the post and a pair of arms are pivotally coupled to the coupler. A pair of springs may bias the arms to the expand or the working position. A pair of beams may be pivotally coupled between the arms and the post for forming a triangular structure. The coupler and the arms and the beams may include a reflective outer surface and may include one or more lights for generating warning signals.
