Biohazard Symbol - Universal Warning Sign for Biological Hazards #131619 (License: Personal Use)

This image shows the standard biohazard symbol-a vivid red trefoil design on a white background-created in 1966 by Charles Baldwin to universally signify biological hazards such as infectious agents, medical waste, or genetically modified organisms. Its high-contrast color scheme and symmetrical geometry ensure immediate recognition even from a distance or under poor lighting conditions. The symbol is mandated by OSHA and ISO standards for labeling containers, equipment, and areas where biohazards are present.

Used on signage, lab equipment, waste containers, and safety documentation in healthcare, research labs, and public health settings; matches user intent for hazard identification, safety compliance, or educational material about biosafety protocols.
