Biohazard Symbol - Universal Warning Sign for Biological Hazards #226861 (License: Personal Use)

This high-contrast red biohazard symbol consists of three interlocking arcs surrounding a central circle, designed for maximum visibility and immediate recognition. Created in 1966 by Charles Baldwin, it is standardized under ISO 3864-3 and used globally to mark areas, containers, or equipment containing biological hazards such as viruses, bacteria, or medical waste. Its design ensures legibility even when partially obscured or viewed from a distance.

Used on signage, lab equipment, medical waste containers, PPE packaging, and safety documentation; matches user intent for hazard identification, regulatory compliance, or educational content about biosafety protocols.
