Alarm Warning Triangle black outline icon

About the Alarm Warning Triangle black outline icon

This icon shows a rounded triangle outline containing a thick exclamation mark, the universal symbol for caution and alert. It communicates warnings, hazards, errors or urgent notices. Use it for error messages, safety warnings, system alerts, form validation or hazard labeling on packaging.

The triangle has smoothly rounded corners with the exclamation point centered and evenly weighted between the vertical bar and the dot below it. It pairs well with alarm bell, danger and information icons. Keep it at a readable minimum size so the exclamation mark stays clear against busy backgrounds.

This is the black outline version of the alarm warning triangle icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.

It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
