Biohazard Symbol - Universal Warning Sign for Biological Hazards #1473592 (License: Personal Use)

This iconic black-and-white symbol consists of three interlocking arcs surrounding a central circle, designed in 1966 by Charles Baldwin to be unmistakable and culturally neutral. It is universally employed to mark containers, equipment, and areas contaminated with biological hazards such as viruses, bacteria, or medical waste. Its high-contrast design ensures visibility and immediate recognition even under stress or low-light conditions.

Used on laboratory signage, medical waste bins, PPE packaging, and biosafety documentation; serves users seeking hazard awareness, regulatory compliance, or educational material on biosafety protocols.
