What does the NFPA 704 System primarily define?

The NFPA 704 System, also known as the "Fire Diamond," is primarily focused on identifying the hazards of specific materials. This system uses a color-coded diamond with four quadrants that denote different types of hazards: health (blue), flammability (red), reactivity (yellow), and specific hazards (white). Each quadrant is filled with a number that indicates the severity of the hazard in a standardized manner, allowing first responders and emergency personnel to quickly understand the risks associated with a material before they approach an incident.

This is particularly crucial in emergency situations, as it informs the response team about necessary precautions and the potential dangers they may face, enabling a safer and more effective response. By understanding these specific hazards, personnel can assess the appropriate handling techniques, personal protective equipment requirements, and emergency measures needed in the event of an incident involving the material.
