Biohazard Symbol - Official Warning Sign for Biological Hazards #1273679 (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 convey danger without language barriers. It is mandated by OSHA and WHO for labeling infectious waste, lab equipment, and containment zones. Its distinctive shape ensures immediate recognition in emergency, medical, and research settings.

Used on hazardous waste containers, laboratory doors, safety data sheets, and PPE packaging; serves users seeking hazard identification, regulatory compliance, or educational material about biosafety protocols.
