Final answer:
The term used by NFPA for those responsible for enforcing codes or approving procedures and materials is the Authority Having Jurisdiction (AHJ). The NFPA 704 Hazard Identification System is a tool to communicate the hazards of chemicals, using a diamond symbol to rate flammability, reactivity, and health risks.
Step-by-step explanation:
The NFPA term that refers to an organization, office, or individual responsible for enforcing the requirements of a code or standard, or for approving equipment, materials, an installation, or a procedure is known as the Authority Having Jurisdiction (AHJ). The AHJ plays a critical role in ensuring that fire and safety codes are applied correctly within their governed territory. When referring to the NFPA 704 Hazard Identification System, the AHJ would be responsible for ensuring that the correct hazard ratings are applied and that all safety procedures are followed in relation to the identified hazards of a chemical substance.
The NFPA 704 system helps identify the flammability, reactivity, health, and other hazards of chemicals through a recognizable diamond symbol, with different colors representing different types of hazards. Each hazard is rated on a scale from 0 to 4, with 0 indicating no hazard and 4 indicating the most extreme hazard. This system is widely used across various industries to contribute to workplace safety.
