Biohazard Symbol - Official Warning Sign for Biological Hazards #3821486 (License: Personal Use)

This image displays the internationally recognized biohazard symbol-a black trefoil (three-leaf) design centered in a yellow equilateral triangle with a black border, accompanied by the word “BIOHAZARD” in bold uppercase letters on a matching yellow rectangular panel beneath. The high-contrast color scheme ensures visibility and immediate recognition, critical for alerting personnel to potentially infectious or hazardous biological materials. It is standardized by ISO 3864-3 and OSHA guidelines for use in laboratories, healthcare settings, waste disposal, and transport.

Used on containers, doors, equipment, and signage in medical, research, and industrial environments where biological agents pose a risk. Matches user intent for safety education, regulatory compliance, hazard identification, or visual reference for designers and safety officers.
