Biohazard Symbol - Universal Warning Sign for Biological Hazards #3529993 (License: Personal Use)

This iconic black-and-white 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 universally employed to mark substances or areas contaminated with potentially infectious agents, including viruses, bacteria, and genetically modified organisms. Its high-contrast design ensures visibility and compliance with international safety standards such as ISO 7010 and OSHA regulations.

Commonly used on laboratory equipment, medical waste containers, biosafety cabinets, and hazard signage in healthcare, research, and industrial settings. Matches user intent for safety information, regulatory compliance, or educational material about biological risk management.
