About the CO2 Warning Triangle black outline icon

A rounded-corner triangle holds a second inner triangle border, with the chemical label CO2 set in bold across its center and the 2 as a subscript. It reads as carbon dioxide hazard, asphyxiation risk, emission limits and restricted atmosphere. Suitable for industrial safety signage, gas cylinder and fire suppression labels, environmental reporting dashboards, HSE training decks and carbon footprint infographics.

The double triangle outline gives the sign weight while the lettering stays generously spaced inside, so the shape stays recognizable even when the text blurs. It pairs with other triangular caution, flammable and biohazard signs in the library. Below 32 px keep the frame and drop the inner triangle for clarity.

This is the black outline version of the co2 warning triangle icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
