Biohazard Symbol - Universal Warning Sign for Biological Hazards #2008318 (License: Personal Use)

This high-contrast black-on-orange biohazard symbol is the standardized warning sign for biological hazards, including infectious agents, toxins, and medical waste. Designed by Charles Baldwin in 1966 for the U.S. Centers for Disease Control, it features three interlocking circles radiating from a central point to convey universal recognition regardless of language. Its vivid color scheme ensures visibility and immediate association with danger in clinical, laboratory, and industrial settings.

Used on containers, doors, signage, and protective equipment in healthcare facilities, research labs, waste disposal units, and emergency response contexts; matches user intent for safety compliance, hazard identification, or educational reference.
