Biohazard Symbol - Universal Warning Sign for Biological Hazards #2308925 (License: Personal Use)

This high-contrast black-and-white biohazard symbol consists of three interlocking crescent shapes 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 denote biological substances posing a threat to human health. Its symmetrical, abstract form ensures it is unmistakable even when viewed from a distance or at an angle.

Used on laboratory equipment, medical waste containers, quarantine zones, and biosafety signage; this image serves informational, educational, and compliance purposes-matching user intent for safety guidelines, hazard identification, or academic reference.
