Biohazard Symbol - Universal Warning Sign for Biological Hazards #1475245 (License: Personal Use)

This high-contrast red biohazard symbol consists of three interlocking arcs surrounding a central circle, designed in 1966 by Charles Baldwin to be instantly recognizable regardless of language or literacy. It is standardized by ANSI and ISO for labeling biological hazards including viruses, bacteria, medical waste, and genetically modified organisms. The symbol appears on lab equipment, waste containers, and safety signage in healthcare, research, and industrial settings.

Used on safety signage, lab manuals, hazardous waste labels, and public health alerts; matches user intent for hazard identification, safety compliance, or educational reference about biosafety symbols.
