Biohazard Symbol - Official Warning Sign for Biological Hazards #1475254 (License: Personal Use)

This high-contrast black-and-white biohazard symbol features three interlocking crescent shapes radiating from a central circle, designed for maximum visibility and instant recognition. Created in 1966 by Charles Baldwin, it conveys danger from biological agents such as viruses, bacteria, and genetically modified organisms without relying on language. It is standardized under ISO 3864-3 and OSHA regulations for use in healthcare, research, and waste management.

Used on containers, lab doors, protective equipment, and hazardous waste labels to alert personnel and the public to potential exposure to infectious or toxic biological materials; matches user intent for safety compliance, hazard identification, or educational reference.
