Biohazard Symbol - Universal Warning Sign for Biological Hazards #1207148 (License: Personal Use)

This iconic yellow-and-black biohazard symbol features a trefoil design with three interlocking arcs radiating from a central point, enclosed in a circle. Created in 1966 by Charles Baldwin, it was designed to be instantly recognizable regardless of language or literacy. It is mandated on containers, equipment, and signage where biological agents pose a risk to health.

Used on medical waste bins, lab doors, PPE packaging, and biosafety documentation; targets professionals in healthcare, research, public health, and emergency response seeking hazard awareness and compliance guidance.
