Biohazard Symbol - Universal Warning Sign for Biological Hazards #283897 (License: Personal Use)

This high-contrast black-and-white biohazard symbol consists of three interlocking arcs radiating from a central circle, with serrated outer edges for visual impact. Designed in 1966 by Charles Baldwin at Dow Chemical, it was created to be instantly recognizable regardless of language or literacy. It is standardized under ISO 3864 and used globally to denote biological risks including pathogens, toxins, and biocontaminated waste.

Used on lab doors, medical waste containers, PPE packaging, and safety signage; matches user intent for hazard identification, safety training, regulatory compliance, or educational content about biosafety.
