Which placard color indicates nonflammable gas?

Explanation:
Green indicates nonflammable gas. In hazmat placard systems, Class 2 gases that do not ignite are marked with green to show they are nonflammable. This helps responders know to expect a gas hazard that isn’t flammable, though it may still pose other risks like asphyxiation or pressurized release. Red would mean flammable gas, yellow signals other hazards such as instability or oxidizers, and blue is not used for this gas classification.
