Self contained eye wash fountain
First Claim
1. A self-contained emergency eye wash fountain for siting without connection to a remote source of eye wash liquid, said fountain comprising:
- a fountain base including at least one liquid discharge orifice and a reservoir for holding a supply of eye wash liquid, said reservoir being positioned above said orifice, said base further including a flow channel means connecting said reservoir and said orifice;
at least two separate tanks each containing eye wash liquid supported by sad base and independently removable from said base, each tank having a mouth adjacent its lower end extending into said reservoir, the mouth of each tank being the only opening of that tank, the mouth of one tank being disposed above the level of the other tank, each of said tanks having a bottom wall and a neck dependent from the bottom wall and terminating in said mouth, the neck of said one tank being shorter than the neck of the other tank; and
means for blocking and unblocking the flow of the eye wash liquid from said reservoir t said orifice whereby with said means permitting the flow, said one tank drains before said other tank and the level of the eye wash fluid in said reservoir drops from a higher level to a lower level when said one tank has drained.

Abstract
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.
