Which organization developed a system for identifying hazardous materials using a diamond-shaped symbol?

The National Fire Protection Association (NFPA) developed the well-known diamond-shaped symbol used for identifying hazardous materials. This system, often referred to as the NFPA label or the Fire Diamond, provides critical information about the dangers posed by various substances. It uses a color-coded diamond divided into four quadrants, where each quadrant represents a different type of hazard: health (blue), flammability (red), reactivity (yellow), and specific hazards (white). The numbers within each colored section indicate the degree of severity, helping first responders and others quickly assess the risks associated with a substance.

Understanding this labeling system is vital for safety in environments where hazardous materials are present. It allows individuals to make informed decisions and take appropriate action in emergencies, ensuring the safety of personnel and the surrounding environment. This particular labeling system is distinct from those created by other organizations, which may focus on different aspects of workplace safety or environmental protection.
