Biohazard Symbol - Universal Warning Sign for Biological Hazards #45028 (License: Personal Use)

This iconic black-and-white symbol, designed in 1966 by Charles Baldwin, features three interlocking arcs converging toward a central circle, representing the universal warning for biological hazards. It is mandated by OSHA and WHO guidelines for labeling pathogens, medical waste, and contaminated equipment. Its high-contrast design ensures immediate recognition even under poor lighting or from a distance.

Used on laboratory doors, medical waste containers, safety signage, and hazard documentation; matches user intent for safety compliance, emergency response training, or biosafety education.
