Biohazard Symbol - Official Warning Sign for Biological Hazards #1688964 (License: Personal Use)

This high-contrast black-and-white biohazard symbol consists of three interlocking crescent shapes radiating from a central circle, designed for maximum visibility and immediate recognition. Created in 1966 by Charles Baldwin at Dow Chemical, it has since become the global standard for labeling biological risks including pathogens, medical waste, and contaminated equipment. Its symmetrical, non-representational design ensures cross-cultural understanding without reliance on language or imagery.

Used on lab doors, medical waste containers, PPE packaging, and biosafety signage; this image serves users seeking hazard identification, safety compliance info, or educational material on biosafety standards.
