Which organization publishes standards that set fire safety guidelines?

• A. ASTM International
• B. ISO
• C. NFPA
• D. UL

Answer: (C)

Fire safety guidelines are set by organizations that publish codes and standards used to design, install, and inspect protective systems. The organization most closely associated with this purpose is NFPA—the National Fire Protection Association. They publish widely adopted codes and standards for fire protection and life safety, such as NFPA 101 Life Safety Code and NFPA 13 for sprinkler systems, which form the basis of many building and fire-code requirements. This emphasis on comprehensive fire protection guidance is what makes NFPA the best answer.

ASTM International creates many technical standards across industries, including some related to fire-related testing or materials, but its scope isn’t centered on the fire-safety guidelines used in codes. ISO develops international standards across countless fields, including some fire-related ones, but these aren’t the specific fire-code guidelines that govern building installations in most places. UL focuses on product safety testing and certification, providing standards for individual products rather than the broad fire-safety codes used by authorities having jurisdiction.
