Ref. No.: 09-0221

Dear Mr. Ferguson:

This responds to your September 24, 2009 letter regarding requirements for oxidizers and compressed oxygen when cylinders are transported by air under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171.180). Specifically, you ask whether oxygen cylinders transported by an airline for use by cabin crews in the event of smoke or depressurization in the cabin are eligible for the exceptions provided in § 175.501(e).

The answer is no. Section 175.501(e) applies only to medical-use compressed oxygen that is either owned or leased by the air carrier for passenger use during flights or offered for transportation by a passenger needing it for personal medical use at a destination. Oxygen cylinders transported by an airline to be used in the event of an emergency on board the aircraft must be transported in accordance with the requirements in § 175.8(a) regarding airworthiness and items of replacement (company material (COMAT)).

I trust this satisfies your inquiry. Please contact us if we can be of further assistance.

Sincerely,

Hattie L. Mitchell
Chief, Regulatory Review and Reinvention
Office of Hazardous Materials Standards

175.501(e)
