Step-by-step explanation:
The organization whose mission is to reduce the frequency of fires through the establishment of fire prevention standards is the National Fire Protection Association (NFPA).
The NFPA is a nonprofit organization that develops and publishes fire safety codes and standards. Its mission is to reduce the worldwide burden of fire and other hazards by providing and advocating consensus codes and standards that are widely adopted. Through its codes and standards, the NFPA works towards preventing fires, ensuring the safety of buildings and structures, and promoting fire prevention measures.
For example, the NFPA's hazard diamond, shown in Figure 1.21, summarizes the major hazards of a chemical substance, helping to prevent fires and protect people and property from potential dangers.
