Biohazard Symbol - Universal Warning Sign for Biological Hazards #141658 (License: Personal Use)

This black-and-white biohazard symbol features three interlocking arcs radiating from a central circle, with serrated edges to enhance visibility and convey danger. Created in 1966 by Charles Baldwin at Dow Chemical, it was intentionally designed to be unfamiliar yet memorable, ensuring immediate recognition without prior training. It is standardized under ISO 3864-3 and used globally to mark biological hazards including infectious agents, medical waste, and contaminated equipment.

Used on lab doors, sharps containers, biohazard bags, and safety signage; matches user intent for hazard identification, safety compliance, educational material, or regulatory reference.
