Eyewash units are required by law in all laboratories where a person is exposed to a potential hazard of injury to the eye due to contact with a biological or chemical substance. These units should be located close to the hazard site and must always be fully accessible to laboratory workers. They must also be maintained properly and tested regularly. For further details, consult the University of Toronto Emergency Eyewash and Shower Standard.
Every lab must have an eye wash station. If there is one is not plumbed into your lab, you must have a portable one, similar to a 1L squirt bottle of sterile saline or water. Portable eye wash stations are available via UShop.
