Biohazard Symbol - Universal Warning Sign for Biological Hazards #1475249 (License: Personal Use)

This high-contrast red biohazard symbol-composed of three interlocking arcs surrounding a central circle-is standardized by ANSI and ISO for marking biological risks including viruses, bacteria, and medical waste. Designed in 1966 by Charles Baldwin, it conveys hazard without language dependence, making it effective across global contexts. Its bold, symmetrical form ensures visibility and immediate recognition in labs, hospitals, and transport packaging.

Used on signage, lab equipment, medical waste containers, and safety documentation to alert personnel and the public to biological hazards; matches user intent for hazard identification, safety compliance, or educational reference.
