Model 7541 is a wall-mounted, dual bottle personal eyewash station that includes one 500 ml (16.9 fl oz) Sterile pH Neutral solution bottle and one 1000 ml (33.8 fl oz) Sterile Saline solution bottle. With two wash streams, the DUO eyewash provides simultaneous eye coverage allowing for both eyes to be treated with an advanced rinse process for supplementary flushing support. The ergonomic eyecups provide for an effective and comfortable flushing flow. The sterile pH Neutral phosphate solution is able to neutralize any acidic or alkali substance that enters the eyes to help restore a proper pH balance. To activate, twist the cap in the direction of the arrow and place eyecups over the affected eyes. Tilt head backwards with eyes open wide and squeeze the bottle to provide the desired flow level. Recommended wash time is 2 minutes with the pH Neutralizer followed by 5 minutes with the Saline solution. Haws Personal Emergency Eyewashes are for use when dirt, dust or other contaminants come into contact with the eyes. The eyewashes provide immediate flushing fluid while the injured person is en route to a primary emergency station. Includes an identification instruction wall sign. Fluid carries a 3 year shelf life. Store at room temperature 41-95° F (5-35° C).
