Biohazard Symbol - Official Warning Sign for Biological Hazards #1689057 (License: Personal Use)

This black-and-white line drawing depicts the internationally standardized biohazard symbol, consisting of three interlocking circles radiating from a central point, designed for high visibility and immediate recognition. Created in 1966 by Charles Baldwin, it is used on containers, labs, and signage to indicate the presence of potentially infectious or hazardous biological materials. Its symmetrical, abstract design ensures legibility regardless of orientation or language.

Commonly used on medical waste bins, laboratory doors, biosafety cabinets, and transport containers; supports user intent related to safety compliance, hazard identification, educational resources, or regulatory guidelines (e.g., OSHA, CDC, WHO).
