Biohazard Symbol - Universal Warning Sign for Biological Hazards #1688903 (License: Personal Use)

This high-contrast yellow-and-black biohazard symbol features three interlocking arcs surrounding a central circle, enclosed within an equilateral triangle. Created in 1966 by Charles Baldwin, it is universally adopted to indicate the presence of infectious agents, toxins, or other biological hazards. Its design ensures visibility and comprehension across language barriers in medical, research, and industrial settings.

Used on containers, lab doors, protective equipment, and hazardous waste labels; this image supports safety training, regulatory compliance pages, and public health resources where users seek hazard identification guidance.
