Which hazard label would be used for a gas that is not flammable but stored under pressure?

• A. Non-flammable compressed gas
• B. Radioactive substance
• C. Spontaneously Combustible
• D. Explosive

Answer: (A)

When choosing a hazard label for a gas, use wording that reflects its actual hazards. If the gas isn’t flammable, you wouldn’t label it as flammable; if it’s stored under pressure, the label should indicate that compressed state. “Non-flammable compressed gas” communicates both key properties: the gas is under pressure (compressed) and it does not ignite (non-flammable). The other options point to hazards that don’t apply to this gas—radioactive substances involve radioactivity, spontaneously combustible refers to materials that ignite on contact with air, and explosive relates to detonation risk. So the best label clearly signals the gas is under pressure while not being flammable. Remember, even non-flammable compressed gases can be dangerous due to the pressure involved, so handle with care and avoid heat or sources of pressure build-up.
