Biohazard Symbol - Universal Warning Sign for Biological Hazards #58637 (License: Personal Use)

This iconic black-and-white symbol, composed of three interlocking circles surrounding a central dot, was developed in 1966 by Charles Baldwin at Dow Chemical to clearly indicate biological hazards. It is used globally on containers, equipment, and facilities handling infectious agents, toxins, or other biohazardous materials. Its high-contrast design ensures visibility and immediate recognition, even from a distance or under poor lighting.

This image is typically used on safety signage, laboratory manuals, public health advisories, and educational materials about biosafety. It matches user intent for identifying hazard symbols, understanding biosafety protocols, or sourcing official warning graphics for compliance.
