About this clipart

This iconic black-and-white symbol consists of three overlapping circles with curved arcs, forming a trefoil pattern around a central circle. Created in 1966 by Charles Baldwin at Dow Chemical, it was intentionally designed to be unmistakable, memorable, and non-cultural to ensure global recognition. It is used on containers, labs, waste bins, and signage where pathogens, toxins, or other biohazards are present.
Used on safety signage, lab equipment, medical waste containers, and regulatory documentation to alert personnel and the public to biological risks; matches user intent for hazard identification, safety compliance, or educational reference.
