Deax Mx. VanSchoonhoven:
This is in response to your letter requesting clarification of
placarding requixements for your liquid oxygen shipments.
Specifically you ask if a bulk shipment of Oxygen, Refrigexated
liquid, 2.2, UN1073, may display an identification number on the
placard depicted in 49 CER 172.530 ox must the
identification numbex appeax on a sepaxate orange panel used in
conjunction with the OXYGEN placard.
Either is acceptable. The placard depicted in $ 172.530 may
display the word "OXYGEN" or the identification number "1073".
Section 172.519 (b) (3) does not permit a non-text placad; that
is, the placard illustrated in § 172.530 showing the oxidizer
symbol and hazard class numbex only, to be used fox placarding
OXYGEN shipments.
I hope this satisfies your inquiry. If you need additional
assistance, please do not hesitate to contact us.
Sincerely,
Hother. mitchell

Dear Mis. Hedgepeth:
:
We operate an 800 gallon liquid orygen delivery vehicle in the states of Nevada and Califomia
A question of proper placarding has come up with the commercial enforcement division of the Nevada
Highway Patrol.
Our tanker operates under Title 49 CFR 173.320. Under section 172 regarding placarding we interpret
that the yellow placard with the UN number 1073 is appropriare. Our local enforcement officer says we
need to run a yellow placard with OXYGEN, as well as the orange panel with the UN 1073 number.
Do wo need to display both markings?
The following is included for your reference.
172.328 (2) I states ID number on placards or orango panel
172.329 (a)
ID nurabers displayed on orango panel or placards
also seo paragraph "C" placards
Thank you very much for your prompt attention to this request, and we appreciate your reply to interwess
Home Medicallax # (702) 857-3233 attention Var.
