Emergency Eye Wash Stations Emergency eye wash stations are required for work environments that may expose employees to harmful chemicals. Though all proper precautions may be taken to prevent chemical exposure, accidents can still happen. Eye wash stations are designed to immediately flush contaminants out of the eyes after exposure. They should be located near high-risk areas and should have the ability to be activated immediately. In addition to emergency eye wash stations, work environments require the installation of drench showers for treating chemical exposure to other areas of the body. These showers will provide a larger volume of water than eye wash stations and can be used to rinse the entire body as well as clothing.
