Biohazard Symbol - Universal Warning Sign for Biological Hazards #228543 (License: Personal Use)

This image displays the internationally recognized biohazard symbol: a black trefoil (three-lobed) design centered within a bright yellow equilateral triangle bordered in black. The high-contrast color scheme ensures visibility and immediate recognition, critical for safety compliance in labs, medical facilities, and waste handling. Developed in 1966 by Charles Baldwin, the symbol is intentionally abstract to avoid cultural bias and maximize universal understanding.

Used on containers, doors, equipment, and documentation to indicate presence of biological agents that pose a threat to human health. Matches user intent for safety education, regulatory compliance, hazard identification, or graphic design reference.
