Green placards identify a nonflammable gas. This color coding helps responders quickly recognize that the material is a gas that does not burn under normal conditions, classified as Class 2, nonflammable gas. Even though it isn’t flammable, it can still pose serious hazards such as asphyxiation, pressure-related release, or other gas-specific risks, so that quick visual cue is crucial. The other colors indicate different hazards (flammable gas, oxidizer/reactivity, health/toxic hazards), so green specifically points to nonflammable gas.
