Which placard color is associated with nonflammable gas hazards?

• A. Blue
• B. Green
• C. Red
• D. Yellow

Answer: (B)

Placard color coding on hazardous materials shipments is designed to let you identify the hazard type at a glance. For nonflammable gas hazards, the green placard is used. This signaling helps distinguish these gases from flammable ones (which use a red-associated warning) and from other hazard types that use different color cues. Nonflammable gases, like nitrogen, helium, or argon, don’t burn but can pose other risks such as oxygen displacement or high-pressure hazards, so the green color quickly signals responders and handlers to approach with appropriate precautions. Remember to always verify the specific label and safety data sheet for the exact gas, as handling requirements can vary.
