Where is the information indicating units used in NFPA codes and standards located?

• A. Chapter 5 (Hazardous Materials).
• B. Annex A.
• C. Chapter 9 (Ventilation).
• D. Chapter 1 (Administration).

Answer: (D)

The key idea is that measurement policy and the system of units for the entire NFPA code are set at the administrative framework level. Chapter 1 Administration establishes how quantities are stated, which unit system is used, and how conversions or references between units are handled, so every technical section that follows can rely on a consistent approach. This makes Chapter 1 the place to look for how units are used throughout the standard. Other chapters focus on specific topics (like hazardous materials or ventilation) and Annex A provides supplementary or informative material, but they don’t establish the overall unit policy.
