Biohazard Symbol - Official Warning Sign for Biological Hazards #131600 (License: Personal Use)

This high-contrast yellow-and-black biohazard symbol is the standardized warning sign for biological agents that may cause disease in humans, animals, or plants. Designed in 1966 by Charles Baldwin, it features three interlocking arcs around a central circle, ensuring visibility and recognition across languages and cultures. It appears on containers, lab doors, waste bins, and transport packaging involving pathogens, recombinant DNA, or infectious materials.

Used in medical facilities, research laboratories, waste disposal sites, and biosafety training materials; matches user intent for hazard identification, safety compliance, or educational reference.
