Emergency Washing Equipment

Emergency washing equipment (EWE) is provided in UW facilities for the purpose of rinsing chemicals or other harmful agents from the eyes or skin. It is an important safety tool that can prevent or limit damage to the body from exposure to harmful agents. Examples include:

Eye wash

Eye washes are required in areas where any of the following agents are used: corrosives; strong irritants; or toxic chemicals of concern. An eyewash is also required in a BSL-2 or BSL-3 laboratory, regardless of whether the above agents are used.

Caution Sign for Hazards


Laboratories, shops and maker spaces where hazardous materials are used or stored are required to post an up-to-date sign at the entrance. The sign is intended to alert emergency responders and visitors of potential hazards and precautions for entry.

EH&S installs the sign holder and posts the initial sign. Occupants update signs as needed using the tool available on the MyChem menu.

Laboratory Safety Initiative

The UW launched a two-year Laboratory Safety Initiative (LSI) as part of a national movement to build a stronger culture of safety in university research laboratories. This initiative is intended to lead to the development and implementation of services, approaches, best practices and tools that significantly improve laboratory and chemical safety throughout the University.
