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.

A push plate for moving a flow control valve in a covered eye wash fountain is interconnected with a cover whereby opening the flow control valve also opens the cover while simultaneously providing independent opening and closure of the cover without moving the push plate, and simultaneously providing closure of the flow control valve from an open position without closing the cover. The covered eyewash fountain embodying the present allows the cover to be raised and the fountain inspected, cleaned, serviced, or repaired without opening the flow control valve.

An emergency water release device comprises heating elements adapted to heat water, a shower and an eyewash, a valve and a controller which sends a first signal to turn off at least one of the plurality of heating elements when a temperature of the water exceeds a predetermined limit, and when a flow rate of the water is reduced to a reduced flow rate, the valve opens so that water is dispersed away from both the shower and the eyewash in an amount equal to the difference between the flow rate and the reduced flow rate. The heating elements form a first set electrically connected in series which provides heat for water to be dispensed by the shower, a second set electrically connected in series which provides heat for water to be dispensed by the eyewash. The first and second set of heating elements can be connected in parallel. The controller may also be configured to send a signal to another valve to open so that unheated water is mixed with heated water.

The present invention provides a portable eyewash system having a main conduit able to receive fluid from various fluid sources.
