Biohazard Symbol - Universal Warning for Biological Hazards #1688937 (License: Personal Use)

This high-contrast white biohazard symbol on a black background is the standardized warning sign for biological hazards, including viruses, bacteria, toxins, and other infectious agents. Designed by Charles Baldwin in 1966, its distinctive trefoil shape ensures immediate recognition across languages and cultures. It is mandated in laboratories, medical facilities, waste disposal units, and transport containers handling biohazardous substances.

Used on signage, packaging, lab equipment, and safety documentation to alert personnel and the public to potential exposure to dangerous biological materials; matches user intent for hazard identification, safety compliance, or educational reference.
