The EH&S Laboratory Design Guide is not “all inclusive.” It does not cover all regulatory issues nor does it cover all design situations. It is important to note that use practices must be considered during the design process, as they can directly influence how the laboratory will be designed (e.g., how hazardous materials are used impacts how they are stored, which is a design issue). In all cases, EH&S should be consulted on questions regarding health, safety, and environment.
