Reference No. 16-0059
Dear Mr. Xie:
This letter is in response to an April 6, 2016, email from Mitchell Brown (Chief Investigator,
Eastern Region, Field Services Support Division, PHMSA) in which he forwarded your
inquiry and requested clarification of the Hazardous Materials Regulations (HMR; 49 CFR
Parts 171-180) applicable to the transport of "UN 1044, Fire extinguishers, 2.2 (non-
flammable gas)" by motor vehicle in the United States. We have paraphrased and answered
your questions as follows:
Q1.
Must fire extinguishers in the United States be described as "UN 1044, Fire
extinguishers, 2.2'?
Al.
Only fire extinguishers that comply with the requirements prescribed in § 173.309
must be described as "UN 1044, Fire extinguishers containing compressed or
liquefied gas, 2.2." A fire extinguisher that varies from these requirements must be
described appropriately for the hazardous material(s) it contains. For example,
§ 173.309(a)(3) requires that UN 1044 fire extinguishers must contain 30 percent or
less carbon dioxide by volume. Fire extinguishers that exceed this percentage may be
described as "UN 1013, Carbon dioxide, 2.2," or may have different or additional
Permit (DOT-SP).
description requirements authorized under a Department of Transportation Special
Q2.
What is the correct way to transport fire extinguishers in the United States by motor
vehicle?
A2.
Fire extinguishers authorized under § 173.309 must comply with that section's
ransportation in commerce. These requirements include relief from shipping papers.
landling, packaging, operation, and test requirements before being offered fo
labels, and placards and from having to comply with the modal requirements in 49

<<<PAGE 2>>>

CFR Parts 174 (rail) and 177 (highway). Section 173.309 fire extinguishers are also
eligible for the exceptions in § 173.156. As previously stated, fire extinguishers that
do not comply with § 173.309 but meet the definition of a hazardous material must
comply with the HMR requirements applicable to the hazardous materials they
contain. For example, these cylinders must be loaded, secured, and unloaded on a
motor vehicle in conformance with 49 CFR Part 177 unless they meet the limited
quantity exception. Please note that other Federal agency regulations may also apply.
Q3.
Why aren't all fire extinguishers in the United States marked and labeled with a green
NON-FLAMMABLE GAS (Division 2.2) compressed gas label prescribed in
§ 172.415? Is this label only required when a fire extinguisher is shipped by vessel?
A3.
As previously stated, fire extinguishers that comply with § 173.309 are excepted from
being labeled with a NON-FLAMMABLE GAS hazard warning label. Fire
extinguishers that do not comply with § 173.309 must be marked and labeled as
required under the HMR. For example, fire extinguishers required by the HMR to be
placed in an outer packaging before being offered for transportation (such as a
fiberboard box authorized under a DOT-SP) must be marked and labeled on the outer
packaging in conformance with the HMR. Fire extinguishers that are permitted by
the HMR to be placed in transportation without an outer packaging must themselves
be marked and labeled as prescribed in 49 CFR Part 172, Subpart E (labeling).
Q4. Are there special regulations in the United States for delivering Division 2.2 fire
extinguishers other than those assigned identification number "UN 1044"?
A4.
As previously stated, the answer is yes. Division 2.2 fire extinguishers other than
those assigned identification number "UN 1044" must be offered for transportation in
commerce in conformance with the HMR for the hazardous materials they contain.
Q5.
Are only those fire extinguishers manufactured in conformance with § 173.309
required to be classified as "Division 2.2" and assigned identification number "UN
1044"?
A5.
The answer is no. Please see A4.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
Isten Taster

Subject: INFO: Fire Extinguishers
Greetings Mr. Foster,
I have a several questions for you....attached please find copies of Compliance Certificates relative to Fire
Extinguishers. The company specifically asked whether the extinguisher(s) must be described as UN1044, fire
extinguisher, 2.2
when transporting via highway in the US. These extinguishers will contain dry chemical product that are not hazardous
materials. The questions are as follows::
Do the fire extinguishers in USA need to be delivered under UN1044 class 2.2??
What is the right way to delivery fire extinguishers in USA by truck?
Why aren't all fire extinguishers in USA not marked and labeled with the Green Label UN1044 class 2.2; in
Europe they are? Is this only a requirement when shipped via vessel?
Is there a special regulation of delivery fire extinguishers in USA other than UN1044 class 2.2?

Are only those extinguishers manufactured under section 173.309, required to be shipped under UN1044 class
Any assistance that you might be able to provide on this matter would be greatly appreciated. Again, the
company is looking to transport their fire extinguishers via highway.
