Biohazard Symbol - Official Design, Meaning, and Safety Usage #1207573 (License: Personal Use)

This image displays the standard biohazard symbol-a black trefoil composed of three interlocking arcs surrounding a central circle-set against a white background. Created in 1966 by Charles Baldwin at Dow Chemical, it was adopted globally as ISO 3864-3 compliant signage to denote infectious agents, medical waste, or contaminated materials. Its high-contrast, symmetrical design ensures visibility and legibility from multiple angles and distances.

Used on lab doors, medical waste containers, PPE packaging, and safety manuals; this image serves users seeking authoritative visuals for compliance, education, or hazard communication training.
