A self-contained emergency eye wash fountain. The fountain includes a base having a spray nozzle, upstanding walls defining an open top and a flow channel extending from an inlet end adjacent to the upstanding walls to the spray nozzle. The fountain base holds at least one removable tank containing eye wash liquid. The tank has a mouth adjacent its lower end for providing its contents to a reservoir. If two tanks are used, they are configued so that one drains before the other. The fountain also contains electronic circuitry for indicating that the fountain is ready for use, that the tanks should be replaced because one is empty and for indicating that a predetermined long time has expired since the tanks were mounted. Methods of using the fountain are also disclosed.
