Skull and Crossbones Symbol - Universal Warning Icon for Poison and Hazard #3669317 (License: Personal Use)

This high-contrast, monochrome illustration depicts a stylized human skull positioned above two crossed femur bones, forming the iconic "skull and crossbones" motif. The design is minimalist yet instantly recognizable, with bold outlines and solid black features against a transparent background, making it ideal for labeling hazardous materials. Its origins trace back to piracy and later evolved into a standardized hazard symbol under international safety protocols like GHS.

Commonly used on chemical containers, pesticide labels, pharmaceutical warnings, and safety data sheets to denote acute toxicity; also appears in digital interfaces, educational materials, and regulatory documentation where visual hazard communication is critical.
