Biohazard Symbol and Warning Sign - Safety Identification Guide #131565 (License: Personal Use)

This high-contrast biohazard warning sign uses a vivid red background with black text and symbol to ensure immediate visibility and recognition.

It is commonly affixed to containers, doors, equipment, and transport vehicles handling infectious agents or contaminated materials.
