The California edition of NFPA 2006 is based on which NFPA 25 edition?

• A. NFPA 25 2010
• B. NFPA 13
• C. NFPA 25 2002
• D. NFPA 70

Answer: (C)

The thing this question tests is which cross-reference edition NFPA 25 the California edition of NFPA 2006 relies on. The correct choice is NFPA 25 from 2002. This edition was the version in common use when the California edition of NFPA 2006 was published, so the maintenance and inspection requirements it contains align with the lab-fire-protection context NFPA 2006 addresses.

Why the other options don’t fit: NFPA 25 2010 is a later edition and would not be the base cross-reference for the California edition, which was established earlier. NFPA 13 covers sprinkler system design and installation, not the maintenance references used by NFPA 2006. NFPA 70 is the National Electrical Code, unrelated to the cross-referenced maintenance of water-based fire protection systems.
