  • Patent number: 5157798
    Abstract: A transparent emergency eye wash fountain is provided having a portable unitary housing including a fold down tray carrying spray nozzle means for discharge of an eye wash fluid onto the eyes. The fluid is discharged by folding down the tray to open a valve. A liquid reservoir is positioned above the nozzle means and opening of the valve causes discharge eye wash fluid through the nozzle in a sustained gravitationally fed stream from said reservoir. The housing is formed of a tough, impact resistant transparent injection molded polymer. The injection molded polymer preferably has an optical transmission of at least 45% in accordance with ASTM Method #D-1003, which enables viewing through the wall of the fluid level within the housing as well as the presence of harmful contamination.
