Poison Warning Sign - Hazard Symbol for Toxic Substances #1355011 (License: Personal Use)

This high-contrast safety sign uses a bold black skull and crossbones icon centered above the capitalized word “POISON” on a vivid yellow field, enclosed by a thick black border. Designed for immediate recognition, it follows international hazard communication standards to warn of lethal or highly toxic substances. The sign is universally understood across languages and contexts where chemical or biological hazards are present.

Used on chemical containers, laboratory doors, industrial sites, and safety manuals to indicate presence of poisonous materials; matches user intent for hazard identification, safety training, or regulatory compliance guidance.
