Biohazard Symbol - Universal Warning Sign for Biological Hazards #221043 (License: Personal Use)

This image shows the standard biohazard symbol, a trefoil-shaped red icon developed in 1966 by Charles Baldwin at Dow Chemical to denote biological substances hazardous to living organisms. Its symmetrical, abstract design ensures visibility and recognition regardless of language or literacy level, making it essential in laboratories, medical waste handling, and pandemic response settings.

Used on signage, containers, protective gear, and documentation to alert personnel and the public to potential exposure to infectious agents, toxins, or genetically modified organisms; matches user intent for safety education, regulatory compliance, or hazard identification resources.
