Biohazard Symbol - Official Warning Sign for Biological Hazards #3735103 (License: Personal Use)

This image displays the standard biohazard warning symbol-a black trefoil (three interlocking circles) centered within an equilateral orange triangle with a thick black border. Designed in 1966 by Charles Baldwin, the symbol is universally used to indicate the presence of potentially infectious agents or biological materials requiring special handling. Its high-contrast color scheme ensures visibility and immediate recognition in medical, research, and industrial environments.

Commonly used on containers, doors, equipment, and signage in laboratories, hospitals, waste disposal facilities, and biotech settings. Matches user intent for safety compliance, hazard identification, educational material, or regulatory documentation.
