    Of course it is hazardous.

    It is one of the nine hazardous agent/materials recognized by EPA, DOT and other regulatory agency.

    A discarded wound wrapping is a hazardous waste.

    OP did not deserve to be vetted and pilloried by a mob ganging up on him that are only looking from their own perspective.

    All gases can be classified as flammable or non-flammable. Either classification that they belong to, doesn't remove them from being hazardous.

    Easy on the NEC. . . sometimes it can be a pitfall.
    In post #7 he provided the context; NEC section 517. The NEC doesn't care if it's a hazard because it's a pressurized gas.

    At the risk of beating a dead horse...

    At section 517.61 each subsection A, B, and C qualifies the word "Hazardous" with the word "Classified". In fact if you search the entire article 517 you will not find the word "pressure" or "pressurized" used in context with anesthetic gases. The only characteristic element they are concerned about is if the gas is flammable. The stuff could be stored at 6,000 psig and the NEC wouldn't care.

    Defintuon article 517 NEC anesthetizing location includes flammable or non flammable gas. Also not sure where pressurize gas is coming from inly cared about nitrous oxide is classified hazardous or not at dentist office.

    OP was given correct answers early in the thread and the conversation is not going anywhere so it's time to close it.
