Biohazard Symbol - Universal Warning Sign for Biological Hazards #1475281 (License: Personal Use)

This high-contrast red biohazard symbol features three interlocking arcs radiating from a central circle, designed for maximum visibility and instant recognition. Created in 1966 by Charles Baldwin, it’s standardized under ISO 3864 and used globally to denote biological hazards including infectious agents, toxins, and biomedical waste. Its symmetrical, non-representational design ensures cross-cultural comprehension without reliance on language or imagery.

Commonly displayed on lab doors, medical waste containers, PPE packaging, and safety signage; used when users seek hazard identification, OSHA compliance guidance, or educational material about biosafety protocols.
