Dear Mr. Ritchie:

This is in response to your letter of August 3, 2001, requesting information regarding the transportation of oxygen cylinders on a passenger-carrying bus under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  Specifically, you ask if a spare oxygen cylinder may be carried aboard a passenger carrying bus as a material of trade as provided in § 173.6.

The answer is yes.  By definition, a Material of Trade includes a hazardous material that is carried on a motor vehicle for the purpose of protecting the health and safety of the motor vehicle operator or passengers (see § 171.8). All the conditions of § 173.6 must be met.

I hope this satisfies your inquiry.
