Biohazard Symbol - Universal Warning Sign for Biological Hazards #1688902 (License: Personal Use)

This high-contrast black-on-orange biohazard symbol is the internationally recognized warning sign for biological substances that pose a threat to human health, such as viruses, bacteria, fungi, and toxins. Designed by Charles Baldwin in 1966, its symmetrical, non-directional shape ensures visibility from any angle and avoids cultural misinterpretation. It is mandated by OSHA, CDC, and WHO guidelines for labeling biohazardous waste, labs, and medical facilities.

Used on lab doors, sharps containers, transport packaging, and safety signage; targets professionals in healthcare, research, and hazardous waste management seeking compliance, risk awareness, or training materials.
