About the High Temperature Triangle Warning color filled icon
A red rounded triangle frames a thermometer with a full bulb and rising scale marks, the standard hazard pictogram for high temperature. It warns of hot surfaces, overheating equipment and heat-stress conditions. Use it on factory and workshop signage, appliance manuals, HVAC and machinery dashboards, laboratory safety sheets, and weather apps flagging extreme heat alerts.
The triangle uses soft rounded corners and a thick stroke, leaving the thermometer centered with clear space around it. It sits beside other hazard triangles such as electrical and slippery-floor signs. Keep it at 32 px or larger so the scale marks stay legible.
This is the colour filled version of the high temperature triangle warning icon: a flat, solid-colour shape that stands out in dashboards, marketing pages and app tiles where the icon needs to carry colour meaning.
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.
