Biohazard Symbol - Official Warning Sign for Biological Hazards #226857 (License: Personal Use)

This iconic black-and-white symbol, developed in 1966 by Charles Baldwin at Dow Chemical, consists of three interlocking circles with a central dot, designed for high visibility and universal recognition. It is mandated by OSHA and WHO for labeling containers, equipment, and areas handling infectious agents, recombinant DNA, or other biohazards. Its symmetrical, non-representational design ensures cross-cultural comprehension without reliance on language or imagery.

Used on lab doors, medical waste bins, safety data sheets, and biosafety manuals; serves users seeking hazard identification, compliance guidance, or educational material on biosafety protocols.
