Biohazard Symbol - Official Warning Sign for Biological Hazards #292946 (License: Personal Use)

This high-contrast black-and-white biohazard symbol features three interlocking crescent shapes radiating from a central point, forming a trefoil design. Created in 1966 by Charles Baldwin at the U.S. Centers for Disease Control, it was designed to be unmistakable, memorable, and culturally neutral. It is mandated by OSHA and WHO for labeling biological risk zones, medical waste, and pathogen-handling facilities.

Used on laboratory doors, medical waste bins, biosafety cabinets, and transport containers to alert personnel and the public to biological hazards. Matches user intent for safety compliance, educational resources, or hazard signage procurement.
