Biohazard Symbol | Universal Warning Sign for Biological Hazards #1688805 (License: Personal Use)

This image displays the standard biohazard symbol-a red trefoil design enclosed in a circle-created in 1966 by Charles Baldwin to convey danger from biological substances without relying on language. It is universally used on containers, equipment, and signage in laboratories, medical facilities, and waste disposal sites to indicate the presence of pathogens, toxins, or other biohazards. The high-contrast red-on-white color scheme ensures visibility and immediate recognition across diverse settings.

This image is typically used on safety manuals, lab websites, OSHA compliance pages, public health alerts, and educational content about biosafety. It matches user intent for understanding hazard symbols, preparing safety documentation, or identifying proper labeling requirements for biological materials.
