Upgrade your outdated, under-performing or noncompliant installed emergency eyewash station! This revolutionary inverted flow eyewash head is the only one on the market that provides a Medically Superior Response consistent with all EMT, emergency room and doctors' office protocols by sweeping contaminants away from the vulnerable nasal cavity. (Traditional eyewashes irrigate from the outside edge of the eye back toward the nose, where contaminants can then be flushed into the nasal cavity.)
