Biohazard Symbol | Universal Warning Sign for Biological Hazards #284004 (License: Personal Use)

This high-contrast black-and-white biohazard symbol, developed by Charles Baldwin in 1966, features three interlocking arcs radiating from a central circle to signify biological risk. It is universally recognized across medical, laboratory, waste disposal, and public health contexts as a warning for infectious agents, toxins, or contaminated materials. Its design ensures visibility and comprehension regardless of language or literacy level.
