Biohazard Symbol - Universal Warning Sign for Biological Hazards #3838716 (License: Personal Use)

This iconic black-and-white symbol consists of three interlocking arcs radiating from a central circle, forming a trefoil shape. It was developed in 1966 by Charles Baldwin at Dow Chemical to denote biological hazards such as viruses, bacteria, and medical waste. Its high-contrast design ensures visibility and universal comprehension across language barriers.

Used on containers, signage, and protective equipment in healthcare, research labs, and waste management to alert personnel to biological risks. Matches user intent for safety education, regulatory compliance, or hazard identification resources.
