Biohazard Symbol - Universal Warning Sign for Biological Hazards #221043 (License: Personal Use)

This image shows the standard biohazard symbol: a red, symmetrical trefoil design on a white background, created in 1966 by Charles Baldwin at Dow Chemical. It is used globally to denote biological substances that pose a threat to human health, such as viruses, bacteria, or medical waste. The symbol’s high-contrast color and geometric clarity ensure immediate recognition even under stress or low visibility.

Used on lab equipment, waste containers, PPE, and facility signage; serves users seeking safety compliance, hazard education, or regulatory guidance (e.g., OSHA, CDC).
