Purpose: Use this job aid to learn about several examples of Department of Transportation (DOT) labels.
The DOT requires specific labels for hazardous substances shipped by public highways, water, rail, or airfreight.
![The DOT labels for poison gas, non-flammable gas, explosive, corrosive, spontaneously combustible, poison, flammable liquid, radioactive, flammable gas, flammable solid, oxidizer, and infectious substance display.](jaesh_sah_b23_sh_enus_t4302g01.jpg)
A selection of DOT labels
Image | Label | Symbol | Color | Meaning |

F | Poison | Skull and crossbones | White | Substances, liquid or solid, so toxic to humans that they are a hazard to health during transportation. |
G | Flammable Liquid | Flames | Red | Any liquid having a flash point below 100°F. |
H | Radioactive (all classes) | International radioactivity symbol | Yellow above and white below | Any material or combination of materials that spontaneously gives off ionizing radiation. |
I | Flammable Gas | Flames | Red | Any gas meeting the lower flammability limit, flammability limit range, or flame projection range for flame propagation. |
J | Flammable Solid | Flames | Red and white vertical stripes | Any solid having a flash point below 100°F. |
K | Oxidizer and Organic Peroxide | Burning O | Yellow | A substance such as chlorate, permanganate, inorganic peroxide, or a nitrate that yields oxygen readily to simulate the combustion of organic matter. |
