Warning Sign Icon - High-Visibility Caution Symbol for Safety and Alerts #3627723 (License: Personal Use)

This is a universally recognized hazard warning symbol: a bright yellow equilateral triangle with a thick black border, enclosing a white inner triangle that contains a bold black exclamation mark. The design follows ISO 7010 and ANSI Z535 standards for visual safety communication, ensuring high visibility and immediate recognition across cultures and languages. It is commonly used in signage, digital interfaces, manuals, and emergency protocols to draw attention to non-specific but serious risks.

Used in safety signage, web UIs (e.g., error alerts, form warnings), instructional materials, and regulatory documentation. Matches user intent for identifying danger symbols, understanding safety icons, or sourcing vector graphics for design projects.
