Biohazard Symbol - Universal Warning Sign for Biological Hazards #75985 (License: Personal Use)

This high-contrast red-on-white biohazard symbol consists of three interlocking circles radiating from a central point, forming a trefoil shape. Designed in 1966 by Charles Baldwin, it was created to be unmistakable and unintuitive-ensuring recognition regardless of language or literacy. It is standardized under ISO 3864-3 and OSHA regulations for labeling biological hazards including pathogens, bloodborne materials, and recombinant DNA.

Commonly used on laboratory equipment, medical waste containers, biosafety cabinets, and hazard signage in healthcare, research, and industrial settings. Matches user intent for safety compliance, educational content, or emergency response guidance.
