Final answer:
Fire extinguishers must comply with NFPA 10, which is part of the suite of codes and standards provided by the National Fire Protection Agency to ensure safety. The NFPA 704 identification system is a related standard that provides hazard information on chemical substances for emergency response.
Step-by-step explanation:
All fire extinguishers must meet the requirements of the National Fire Protection Agency (NFPA), specifically NFPA 10, which covers portable fire extinguishers. The NFPA has developed various codes and standards to ensure fire safety and prevent potential hazards associated with fire extinguishers and fire suppression systems. For example, fire extinguishers are part of a broader fire protection system that could include elements like foaming plastics or systems designed to combat specific types of fires, such as those involving organic liquids.
Fire safety protocols dictated by the NFPA also incorporate identification systems, such as the NFPA 704 Hazard Identification System, which is used to convey key information about the hazards of a chemical substance. This involves a color-coded diamond with symbols and numbers that communicate the fire hazard (red diamond), health hazard (blue diamond), reactivity (yellow diamond), and other special hazards (white diamond). These ratings assist in decision-making during emergencies and inform users about the appropriate handling and storage of substances.
