What does the green color on a DOT label signify?

The green color on a DOT (Department of Transportation) label signifies that the material is non-flammable. In hazardous materials identification, color-coding is a critical system designed to quickly convey essential information about the nature of the substances being transported.

Green specifically indicates that the substance will not ignite under normal conditions or that it does not pose a fire hazard. This categorization is vital for transport safety, allowing carriers and responders to understand at a glance the properties of materials they are handling.

The other color codes in the labeling system are associated with different hazards, such as flammability, toxicity, and corrosiveness. Each color helps ensure that those involved in transportation, handling, or emergency response can act appropriately based on the risks presented by the materials.
