The term does not include cryogenic containers that are not designed to be connected to a medical gas supply system, e.g., tank trucks, trailers, rail cars, or small cryogenic gas containers for use by individual patients (including portable liquid oxygen units as defined at 868.5655 of this chapter).

(1) Each portable cryogenic medical gas container must be conspicuously marked with a 360deg. wraparound label identifying its contents. Such label must meet the requirements of 211.94(e)(2) of this chapter and the following additional requirements.
