Biohazard Symbol - Universal Warning Sign for Biological Hazards #1475252 (License: Personal Use)

This iconic symbol features three interlocking crescent shapes radiating from a central circle, set against a vivid yellow background with a bold black border. Created in 1966 by Charles Baldwin at Dow Chemical, it was designed to be unmistakable regardless of language or literacy. It is universally used to label containers, equipment, and areas contaminated with infectious agents, recombinant DNA, or other biohazards.

Used on lab signage, medical waste containers, PPE packaging, and biosafety documentation; matches user intent for safety compliance, hazard identification, or educational material about biological risk management.
