  • How the NFPA Handbooks Differ from Codes and Standards

    THE NFPA HANDBOOKS DIFFER FROM CODES AND STANDARDS

    Ever wonder what the difference is between an NFPA® handbook and a code or standard? We’re glad you asked.

    NFPA codes and standards both provide requirements for achieving outcomes. Handbooks take a deeper dive, providing the full text of a code or standard as well as expert commentary and features such as graphics, decision trees, testing procedures, case studies, sample forms and checklists, and other helpful aids to give a better understanding of the reasoning behind the requirements and how to apply them.

    JUST REMEMBER:

    • A code or standard is a framework—a set of rules to follow with a goal to achieve a certain result
    • A handbook is a connector—linking requirements to application by helping you understand the reasoning behind a code or standard

    The simplest way to think about it is that codes and standards list the technical requirements while handbooks explain those requirements to clarify how to apply them.
