Dear Ms. Aeschilman:
This is in response to your letter dated September 19th, 2004 regarding shipping paper
requirements of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180)
Specifically, you ask if the total quantity listed on a shipping paper must be modified to
reflect intermediate drop-offs of medical oxygen cylinders.
As specified in § 172.202(a)(5), the total quantity of hazardous materials covered by a
description must be indicated on a shipping paper, and must include an indication of the
applicable unit of measurement. Cylinders are excepted from this requirement, provided
some indication of total quantity is shown (e.g., "10 cylinders"). A driver is not required
to update a shipping paper to reflect a partial delivery.
I hope this information is helpful. Please contact us if you require additional assistance.
Sincerely,
Chief, Standards Development

Dear Sir or Madam:
I am writing for clarification regarding shipping paper requirements for the delivery of
compressed medical oxygen cylinders. If a delivery person makes multiple stops during
the course of a day, does the shipping paper need to be changed or re-done after each
delivery or is the original "permanent" shipping paper for the day sufficient? Each
delivery is of the same type of cylinder (medical oxygen) and there is a record of each
delivery indicating the recipient and the amount of cylinders received
Thank you for your help.
Sincerely,
Michelord lenin
