Which hazard label applies to a gas stored under pressure that is not flammable?

Explanation:
Gas stored under pressure presents a risk mainly from the pressure itself, and if the gas isn’t flammable, the label should reflect its non-flammable nature along with the compressed-gas state. That’s why “Non-flammable compressed gas” is the best match — it communicates both the fact that the gas is under pressure and that it does not ignite. The other hazards point to completely different risks: radioactive materials, spontaneous ignition in air, or explosive behavior, none of which describe a non-flammable gas kept under pressure.
