Biohazard Symbol - Universal Warning Sign for Biological Hazards #169401 (License: Personal Use)

This image displays the standard biohazard symbol, a trefoil-shaped icon with three interlocking arcs radiating from a central point, rendered in vivid red against a white background. Designed in 1966 by Charles Baldwin, it conveys immediate visual warning of potentially infectious agents, toxins, or contaminated materials. Its high-contrast design ensures visibility and recognition across languages and contexts.

Used on containers, lab doors, protective equipment, and waste disposal units to alert personnel to biological hazards; matches user intent for safety education, regulatory compliance, or hazard identification resources.
