Biohazard Symbol | Universal Warning Sign for Biological Hazards #3735104 (License: Personal Use)

This high-contrast black-and-white symbol features three interlocking arcs radiating from a central circle, designed for maximum visibility and instant recognition. Created in 1966 by Charles Baldwin at Dow Chemical, it was standardized by ANSI and adopted globally to indicate biological hazards such as pathogens, toxins, or biocontaminated materials. Its symmetrical, non-representational form ensures cross-cultural comprehension without reliance on language or imagery.

Commonly used on lab doors, medical waste containers, PPE signage, and biosafety level documentation; users seeking this image typically need it for safety compliance, educational materials, or hazard communication design.
