The red top quadrant indicates flammability, blue left indicates health hazard, yellow right indicates reactivity/instability, and white bottom denotes special hazards like oxidizers or water reactivity. Each section is rated numerically (0-4) to communicate severity levels at a glance.

Used on chemical containers, safety data sheets, and industrial facility signage to quickly convey risks to emergency responders and workers; matches user intent for safety training, regulatory compliance, or hazard communication.
