The DOT Placarding System requires a vehicle carrying nonflammable compressed gas to display a placard colored:

Explanation:
Color coding in the DOT placarding system helps responders identify hazard type at a glance. For gases, the background color indicates the danger category, and nonflammable compressed gases use a green placard. This quick cue tells you the gas isn’t flammable, even though it remains hazardous because it’s stored under pressure and can cause problems like asphyxiation or injury from a sudden release. The green color distinguishes it from other gas hazards that use different colors, guiding the appropriate safety and emergency response actions.
