ABSTRACT:
An eyewash fountain, particularly useful in industrial and laboratory environments, includes a pair of spray heads mounted on a distribution arm that is connected to a valve. The valve has a rotatable body that is connected to a base by a reversible retainer permitting the valve to be installed on either the left or right side of a sink or drain, and the distribution arm along with the spray heads swung or, alternatively, lowered to a position over the sink. The single action of moving the distribution arm over the sink is sufficient to initiate a flow of fluid to the eyes. Each of the spray heads has an internal volumetric flow regulator, a fluid pressure distributor or diffuser, and a large number of small apertures in the face of each head which direct a uniform, evenly distributed, low pressure flow of fluid to the eyes. Each of the spray heads also have an individual protective cover, mounted at a selectively variable position on each head, that is moveable away from its protective position in response to a flow of fluid from the apertures in the face of the spray head. The emergency eyewash fountain solves problems associated with ease of operation, fluid pressure and distribution control, protective enclosure of the spray heads during potentially long periods of nonuse, cleanability, serviceability, and adaptability to plural mounting positions.
