The latest edition of the NFPA Glossary of Terms (GOT) is available for FREE online. Visit www.nfpa.org/got to download your copy.
The GOT is a list of the defined terms in all of NFPA's published codes, standards, guides and recommended practices. The 14,575 terms are listed alphabetically and assembled into a free PDF available on the NFPA website. The document is used in a number of ways. It helps NFPA Technical Committees who are looking to define new terms or compare existing terms. It also helps members of the public who are interested in learning about how NFPA documents define specific terms. The Glossary of Terms Advisory Committee helps regulate the number of unnecessary duplicate definitions to try and make the GOT easier to use. The GOT contains the following details about each term:
Term: The word being defined.
Definition:The description of the term.
Document (Edition): Where the term and definition are found (document #) and the edition year of that document.
Document Defining Same Term: A list of all documents that also define the same term.
Document Using Same Definition: A list of all documents that also define the same term in the exact same way.
See the figure below for an example of how the GOT is organized. The term "Barrel" is defined in four documents: NFPA 1, NFPA 30, NFPA 59A, and NFPA 80. NFPA 1 and NFPA 30 both define the term in the exact same way. The first 3 definitions refer to a unit of volume while the last definition, from NFPA 80, refers to a rolling steel door component.
