Biohazard Symbol - Universal Warning Sign for Biological Hazards #169417 (License: Personal Use)

This image displays the standard biohazard symbol, a red trefoil (three-part) shape on a white background, designed in 1966 by Charles Baldwin to alert people to biological hazards such as infectious agents, toxins, or medical waste. Its high-contrast color scheme and geometric form ensure visibility and instant recognition across languages and cultures. The symbol is mandated by OSHA and ISO standards for labeling contaminated materials and restricted areas.

Used on signage, lab equipment, waste containers, and PPE in medical, research, and industrial settings to communicate biological danger; matches user intent for safety compliance, hazard education, or graphic asset sourcing.
