Abstract
An improved emergency wash station is provided for flushing irritants from the eyes or face of an individual, particularly such as a person working in an industrial or laboratory environment. The wash station includes a spray manifold having a large plurality of spray ports disposed above the upper rim of a drain bowl, with the spray manifold being connected to a water supply via a single inlet fitting located externally of the drain bowl. A pressure control member at the inlet fitting insures a relatively gentle yet substantially full face flush spray throughout a range of water supply pressures. In addition, the spray ports are formed with an outwardly expanding taper to minimize clogging by ice or other debris.
