Dear Mr. Kimball:
This is in response to your e-mail asking w~ether a hazardous article described as "Fire
extinguisher, 2.2, UN 1044" conforming to 49 CFR § 173.309( a) of the Hazardous
Materials Regulations (HMR; 49 CFR PartsI171-180) meets the definition of limited
quantity in § 171.8. Your questions are paraphrased and answered as follows:
QI. Can a hazardous article described in !accordance with the § 172.101 Hazardous
Material Table as "Fire extinguisheri 2.2, UNl044!1 be considered a limited quantity
I
under theHMR? i
AI. Yes. The requirements for fire extinbishers are found in § 173.309 of the HMR.
In order to qualify under the limited quantity provisions, a fire extinguisher must
full y meet the limited quantity requirements contained in § 173 .309( a) through
• 173.309(a)(3)(iv). If the container is! packaged and offered for transportation in
accordance with § 173.309(a) through 173.309(a)(3)(iv), the limited quantity
provisions apply. . i •
I
Q2. Assuming the answer to Q1 is yes, ifIa fire extinguisher is packaged and offered for
transportation under the limited quantity provisions in § 173.309 (a), is a shipping
paper required? We note that§ 172,:fOO(b)(3) excepts limited quantity packages
from shipping papers for transportation by highway or rail.
A2. Yes. The shipping paper requiremen~s specified in § 173.309(a) take precedence
over the shipping paper exception fo~ limited quantity packages in § 172.200(b )(3).
I trust this satisfies your inquiry. Please con~act us if we can be of further assistance.
Sincerely,
T. Glenn Foster
Chief, Regulatory Review and Reinvention Branch

Subject: Formal interpretation request for 173.309
Good morning Ms. O'Donnell,
Referencing our conversations regarding whether fire extinguishers meeting the requirements of 173.309(a) could be
shipped as "limited quantity" and marked per section 172.315(a), and, shipped without shipping papers per
172.200(b)(3), your response was that fire extinguishers were not eligible for treatment as "limited quantity". Since our
last conversation, it was brought to our attention that there is an existing interpretation, 02-0149, which contains these
two questions and answers:
Q. Can a hazardous material classified in accordance with § 172.101 Hazardous Material Table as "Fire extinguisher, 2.2, UNlO44" be
considered a limited quantity under the HMR and therefore excepted from the emergency response telephone number requirement under §
172.604?
A. The requirements for shipping fire extinguishers are found in § 173.309(a). In order to qualify under the limited quantity provision, a fire
extinguisher must fully meet the limited quantity requirements contained in § 173.309(a) through 173.309(a)(3)(iv). If the container is
packaged and offered for transportation in accordance with § 173.309 Ca) through 173.309(a)(3)(iv) the limited quantity provision applies,
and the package is excepted from the emergency response telephone number requirement in § 172.604.
Q. If a fire extinguisher is packaged and offered for transportation under the limited quantity provision in § 173.309 (a) must the description
on the shipping paper include the words "Limited Quantity" or "Ltd Qty" as specified in § 172.203(b)?
A. Yes. Section 172.203(b) requires offerors of hazardous materials as limited quantities, including fire extinguishers, to include the words
"Limited Quantity" or "Ltd Qty" following the basic description on the shipping paper.
The first question addresses limited quantity in relation to the emergency response telephone number requirement and
not the question of shipping papers. The second question is based upon the assumption that shipping papers are
required, and addresses the inclusion ofthe words "Limited Quantity" or "Ltd Qty" on those shipping papers.
As we initially discussed, section 173.309 does not except fire extinguishers from the shipping paper requirements found
in 174.24 and 177 .817 (for rail and highway, respectively). So regardless of whether fire extinguishers are eligible for
treatment as limited quantity, it seems that shipping papers are required. Since there appears to be some differing
interpretations on this topic, please consider this email as a request for a formal interpretation with the questions
below.
01. Are fire extinguishers which meet the requirements of 173.309(a) eligible to be shipped as "limited quantity"?
Q2. Does the specific reference in 173.309(a) to the shipping paper requirements 174.24 and 177.817 take precedence
over 172.200(b)(3) for shipments of fire extinguishers by highway or rail and therefore mean that shipping papers are
required regardless of whether fire extinguishers are eligible to be shipped as "limited quantity"?
Thank you for your continuing help with this maUer. We look forward to your earliest response.
Regards,
