Recorded scope and limits
Publisher listing for the current edition of the facility safety sign standard, developed by NEMA. Cited alongside Z535.4 because a field-applied label on facility equipment can reasonably be issued under either, and a review records which rather than restyling it.
Use the task guides below to see how this source informs a labeling decision. Check the publication scope and the edition adopted by your project before applying it. A publisher overview is not the full text of a standard, and software documentation does not prescribe a physical label format.
Read the library’s edition and applicability notes.
