Biohazard

The biohazard icon represents a biological hazard or risk, often used to indicate the presence of a potentially hazardous substance or situation. Biohazards can include infectious agents, toxins, or other biological materials that pose a risk to human health.

In software and digital interfaces, the biohazard icon might be used in applications or websites related to medical or laboratory settings, such as medical research or hazard management. For example, a laboratory management platform might use the biohazard icon to represent a hazardous material or protocol.

From a UX perspective, the biohazard icon communicates a sense of danger and risk. It helps users quickly understand that they are interacting with a hazardous material or situation and take necessary precautions.

Biohazard is one of 1,198 icons in Dinkie Icons, made by atelierAnchor and released under MIT. It is drawn on a 12 × 12 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 BiohazardIcon to components/icons/dinkie-icons-biohazard.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 BiohazardIcon 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 Biohazard icon, or any of 1,198 Dinkie 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 12 × 12 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="Biohazard", so screen readers say what it does.

Yes. BiohazardIcon passes every SVG prop to the svg element, so <BiohazardIcon 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. MIT 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: MIT 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 Dinkie Icons, atelierAnchor and the license.

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