Codes and standards are:

• A. Are uniform throughout the USA
• B. Allow for a variety of performance standards
• C. Are written as minimum standards
• D. Are mandated by the NFPA

Answer: (C)

Codes and standards set the baseline safety requirements that must be met. They are written as minimum standards, meaning they establish the least level of safety considered acceptable. Jurisdictions can adopt these minimums, and many places may require more stringent rules based on local risk factors, so the exact requirements can vary from one location to another.

In the United States, there isn’t a single nationwide code. Different jurisdictions adopt different editions and may add local amendments, so the applicable rules can differ by area. Organizations like the NFPA publish standards, but they aren’t automatically enforceable everywhere; a governing authority must adopt them for them to be binding.
