This image displays the standard biohazard symbol-a black trefoil (three-bladed) shape centered on a bright yellow circular background with a bold black border. Designed in 1966 by Charles Baldwin, it conveys danger from biological substances such as viruses, bacteria, or medical waste. Its high-contrast color scheme ensures visibility and instant recognition across diverse environments.

Commonly used on containers, lab doors, protective equipment, and waste disposal units to alert personnel to biological hazards. Matches user intent for safety information, regulatory compliance, educational content, or hazard identification resources.
