Biohazard Symbol - Official Warning Sign for Biological Hazards #1688926 (License: Personal Use)

This high-contrast red biohazard symbol, designed in 1966 by Charles Baldwin, features three interlocking arcs surrounding a central circle, forming a symmetrical, unmistakable warning icon. It is standardized by ANSI and OSHA for labeling containers, equipment, and areas containing potentially infectious agents, recombinant DNA, or other biohazards. Its universal recognition ensures rapid hazard identification across language barriers in medical, research, and industrial settings.

Used on lab doors, waste containers, PPE, and safety documentation to alert personnel to biological risks; matches user intent for safety compliance, hazard education, or regulatory reference.
