About the High Temperature Warning Triangle black outline icon

A triangular hazard sign frames an upright thermometer whose bulb and column are filled to the top, with three short rays beside it to signal radiating heat. The pairing communicates hot surface, overheating equipment and extreme heat alerts. Use it on product safety labels, machine panels, weather apps, server monitoring dashboards and packaging that must stay cool.

The thermometer sits slightly right of center so the heat rays have room inside the triangle, and the rounded corners keep the sign friendly rather than alarming. It pairs with low temperature, fire and voltage warning icons. Use a red fill version when it marks a real hazard.

This is the black outline version of the high temperature 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.
