Abstract
Abstract A hand held eye wash station includes a collapsible container for containing the eye wash liquid. A spring member for collapsing the container and forcibly expressing the liquid is restrained by a snap release. When eye flushing is necessary the snap release is manually operated to free the spring which in turn collapses the container and expresses the eye wash liquid in a continuous stream.
