This high-contrast red-and-white biohazard symbol is a standardized warning sign designed to alert individuals to the presence of biological hazards such as viruses, bacteria, bloodborne pathogens, or genetically modified organisms. Created in 1966 by Charles Baldwin, it features three interlocking circles radiating from a central point, ensuring visibility and recognition regardless of orientation or language. It is mandated by OSHA and WHO guidelines for labeling contaminated equipment, waste, and containment zones.

Used on laboratory doors, medical waste containers, biosafety cabinets, and hazard signage in healthcare, research, and industrial settings; matches user intent for safety compliance, risk awareness, or educational reference.
