Final answer:
NFPA codes are adopted when referenced in building codes and standards that are enacted by local, state, or federal agencies, integrating fire safety measures in facility design and construction.
Step-by-step explanation:
The NFPA codes for facility design and construction are adopted when referenced in building codes and standards. These building codes and standards, which are often adopted by local, state, or federal government agencies, will specify that compliance with NFPA codes is required as part of the legal regulatory framework. Such references ensure that designers and constructors of facilities integrate safety measures and considerations as proposed by the NFPA, especially in terms of fire prevention and protection.
