Biohazard Symbol - Official Warning Sign for Biological Hazards #1866280 (License: Personal Use)

This high-contrast black-and-white biohazard symbol features three interlocking arcs with serrated edges, centered around a circle, creating a symmetrical, unmistakable warning icon. Developed in 1966 by Charles Baldwin at Dow Chemical, it was engineered for maximum visibility and universality, regardless of language or literacy. It is mandated on containers, lab doors, and medical waste to indicate exposure risk from pathogens, toxins, or infectious agents.

Used on hazardous biological material containers, laboratory signage, medical waste bins, and PPE packaging; serves users seeking safety compliance, hazard identification, or educational resources about biosafety standards.
