Biohazard Symbol - Universal Warning Sign for Biological Hazards #1688989 (License: Personal Use)

This universally recognized biohazard symbol consists of three interlocking crescent shapes radiating from a central circle, enclosed within a bold black equilateral triangle. Designed in 1966 by Charles Baldwin, it conveys high-risk biological materials including viruses, bacteria, fungi, and genetically modified organisms. Its stark contrast and geometric simplicity ensure visibility and immediate recognition across languages and cultures.

Used on containers, lab doors, safety signage, medical waste bags, and PPE to indicate exposure risk from infectious or hazardous biological substances; matches user intent for safety compliance, hazard identification, or educational content about biosafety levels.
