  • Patent number: 8375614
    Abstract: Apparatus and methods for wet floor warnings feature a movable barrier member proximate a doorway at a height elevated above floor level for selective movement between a deployed position in which the barrier member spans at least partially across the doorway and a storage position in which the barrier member is less obstructive to the doorway than in the deployed position for selective display of wet floor warning indicia on the barrier member on a path of sight through the doorway to indicate that the floor surface situated beyond said doorway is wet and may present a slip and fall hazard. The visibility of the warning is improved over floor seated signs, and cleaning personnel going room to room in a large establishment like a hotel, hospital, nursing home, care home, etc. need not transport portable warning signs as they travel the premises.
