A green DOD label marks materials that are...

• A. Highly pressurized materials and gases such as nitrogen, carbon dioxide, or other non-flammable gases which could explode in the heat of a fire
• B. Corrosive materials
• C. Reactive with water
• D. Water-based solvents banned

Answer: (D)

The color on this DoD label is meant to quickly convey a storage/handling restriction for that material. A green label marks that water-based solvents are banned in DoD facilities, so you would not use or bring in a green-labeled container and would follow the approved alternatives or disposal procedures instead. This helps prevent unsafe combinations, compatibility issues with equipment or other chemicals, and regulatory concerns in the operating environment. In practice, other hazard cues (like corrosion, reactivity, or pressurization) are conveyed by different warning cues, not the green restriction shown here. Always follow the green-label guidance and consult the official DoD labeling guidance for exact meanings.
