About BioHazard

A flat, high-contrast biohazard trefoil: three identical, curved blade-like arms arranged symmetrically around a central circle. The blades form open crescent shapes that connect near the center and create triangular negative spaces between them. A concentric ring encircles the central circle and sits behind the inner edges of the three arms.

The mark is rendered in a bright solid red with black used in small central negative gaps; no text is present. The composition is geometric and radial, producing an immediate warning/hazard visual impression.
