Biohazard Symbol - Official Warning Sign for Biological Hazards #1688801 (License: Personal Use)

This high-contrast black-and-white biohazard symbol, designed in 1966 by Charles Baldwin, features three interlocking arcs radiating from a central circle to signal biological danger. It is mandated by OSHA and WHO for labeling containers, equipment, and areas handling pathogens, toxins, or medical waste. Its distinctive shape ensures immediate recognition even when partially obscured or viewed at a distance.

Used on lab doors, sharps containers, PPE packaging, and biosafety signage; serves users seeking hazard identification, regulatory compliance, or educational content about biosafety standards.
