Reference No. 24-0052
Dear Mr. Gaffney:
This letter is in response to your June 18, 2024, email requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the placement of hazard
labels on Department of Transportation (DOT) specification 3A480 cylinders. You explain that
JCI transports 150-pound specification cylinders with a netting around each cylinder to protect
the sidewall of the cylinders during handling in transportation and at customer locations. The
netting is rigid and tight-fitting and binds the required labels (e.g., Class 2, Class 8, and Div. 5.1)
underneath the netting to the sidewall of the cylinder. The labels are non-adhesive labels (i.e., no
adhesive on either the frontside or backside of the label is used to affix the label to the cylinder).
You note that this method of affixing the label allows them to be located on the same surface of
the package and near the proper shipping name marking as required in § 172.406 (a)(1)(ii). You
also provided a photograph of a cylinder using this netting to affix labels. You ask whether a
cylinder netting would meet the intent of § 172.406(b)(2) as “other suitable means of affixing”
labels to a cylinder.
In accordance with § 172.406(a)(1)(i) and (ii), each label must be printed on or affixed to a
surface (other than the bottom) of the package or containment device containing the hazardous
material and be located on the same surface of the package and near the proper shipping name
marking if the package dimensions are adequate. Section 172.406(b) affords certain packages
flexibility to have the label printed on or placed on a securely affixed tag or affixed by other
suitable means (emphasis added). Furthermore, § 172.406(f) requires that a label must be clearly
visible and may not be obscured by markings or attachments (emphasis added). In this instance,
it is the opinion of this Office that placing labels underneath a cylinder netting as described and
shown—via your photograph—may indeed prevent the labels from shifting in orientation or
location such that they remain affixed under normal conditions incidental to transportation, and

<<<PAGE 2>>>

meet the visibility requirements of § 172.406(f)—i.e., the netting does not cause a reduction in
the effectiveness of the the label to properly convey the hazard represented.
PHMSA emphasizes that we considered the specific example presented with your incoming
request about interpreting § 172.406 requirements. It should not be construed from this
interpretation that this method of affixing labels generally meets requirements in all cases. As
both means of affixing a label and visibility are performance standards they must be considered
specific to each scenario.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
Dirk Der Kinderen
Chief, Standards Development Branch

JCI Jones Chemicals, Inc. (JCI) is hereby requesting a formal letter of interpretation of 49
CFR 172.406 (b)(2) which states “A label may be printed on or placed on a securely affixed
tag or may be affixed by other suitable means to a cylinder.
”
(Emphasis added).
JCI supplies 150-pound “cylinders” of Chlorine and Sulfur Dioxide to the water treatment
industry (primarily municipalities). The cylinders are DOT 3A 480 specification cylinders. JCI
applies “cylinder netting” around each cylinder to protect the sidewall when the cylinders are
handled during transportation and at the customer locations. JCI places the required DOT 4” x
4” labels (Corrosive, Inhalation Hazard, and Oxidizer for Chlorine, and Corrosive and
Inhalation Hazard for Sulfur Dioxide) underneath the cylinder netting of each cylinder as the
means of affixing them to the cylinders (the DOT labels are non-adhesive). The cylinder
netting is rigid and tight fitting and JCI has never experienced these labels/tags being lost in
transportation using this method of affixing them to the cylinders. Being placed under the
cylinder netting also allows the labels/tags to be located on the same surface of the package
and near the proper shipping name marking as also required by 172.406 (a)(1)(ii).
The issue in question is what does “securely affixed” mean. We do not interpret this to mean
that the DOT labels need to be glued to or stuck on the cylinder (i.e., with an adhesive
backing). Given that 49 CFR 172.406 (b)(2) specifically states that the DOT labels may be
affixed “by other suitable means to a cylinder”, we believe that the cylinder netting is a

<<<PAGE 4>>>

suitable securement method when the non-adhesive DOT labels are placed underneath them.
Attached is a picture of a chlorine cylinder with the non-adhesive DOT labels placed
underneath the cylinder netting, and a picture of the DOT labels as purchased from JJ Keller.
Please let us know if placing a non-adhesive DOT label underneath the cylinder netting meets
the requirements of 49 CFR 172.406 (b)(2) as a suitable means to affix the label to the
cylinder.
Thank you.
