What does document supersession mean in the NFPA context?

• A. Older NFPA documents are never updated.
• B. NFPA documents are archived but never revised.
• C. Older NFPA documents may be replaced by newer editions.
• D. Supersession refers to replacing outdated labels.

Answer: (C)

Supersession means that when a newer edition of an NFPA standard is published, it replaces the older edition as the active requirement. In practice, design, installation, testing, and inspection should follow the most current edition that the jurisdiction has adopted, because the newer edition incorporates updated requirements, clarifications, and safety improvements. The older edition is considered superseded and typically no longer used as the basis for code compliance, unless a specific jurisdiction or project explicitly requires an older version. The other statements don’t fit NFPA practice: standards are regularly updated, so older documents aren’t kept forever as the current rule; they aren’t simply archived without revision; and supersession isn’t about changing labels but about replacing the entire set of requirements with an updated edition.
