Alert Octagon

The alert-octagon icon represents a warning or alert symbol enclosed in an octagonal shape, signifying caution or potential danger. It is part of the Material Design Icons library created by Pictogrammers, offering a distinct visual cue for alerts. The octagon shape may symbolize complexity or a multifaceted warning.

This icon can be utilized in various digital applications such as safety alerts, system status notifications, or to draw attention to critical information. For instance, it might appear in emergency response systems, network security software, or in applications for managing critical infrastructure. The octagonal shape makes the icon stand out.

From a UX perspective, the alert-octagon icon communicates urgency or risk effectively. It helps users quickly recognize and respond to alerts or warnings, enhancing their interaction with the interface. The distinct shape and clear meaning of the icon contribute to a safer and more intuitive user experience.

Alert Octagon is one of 7,638 icons in Material Design Icons, made by Pictogrammers and released under Apache 2.0. It is drawn on a 24 × 24 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds AlertOctagonIcon to components/icons/mdi-alert-octagon.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed AlertOctagonIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Alert Octagon icon, or any of 7,638 Material Design Icons icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Alert Octagon", so screen readers say what it does.

Yes. AlertOctagonIcon passes every SVG prop to the svg element, so <AlertOctagonIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. Apache 2.0 allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: Apache 2.0 only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Material Design Icons, Pictogrammers and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
