  • Emergency eyewash apparatus
    Patent number: 6520431
    Abstract: An eyewash apparatus is disclosed that can be utilized on either side of an associated bowl or sink. Piping extending from spray heads to a housing overlaying a valve can be rotated into position over the sink or bowl. Rotation of the piping initiates or shuts off water flow to eyewash outlets at one end of the piping. The amount of rotation is limited by interaction of a pin traveling in an arcuate slot formed in that part of the apparatus secured to a surface adjacent the sink or bowl. The apparatus can be used on opposite sides of the sink or bowl without a structural change to any components of the apparatus.
