Dear Mr. Watt:
This is in response to your letter dated January 6, 1998, requesting clarification on the
Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if an
"ARMLOK" transportation ring (plastic circular locking ring) used to reinforce the seal of a
in § 173.181(b) of the HMR.
paint can lid meets the requirement for a positive (not friction) means of closure as specified
Based on the photograph and product information on the "ARMLOK" transportation ring
:
provided in support of your letter, it is the opinion of this Office that an "ARMLOK" meets
the requirement for a positive (not friction) means of closure as specified in § 173.181(b).
I hope this answers your inquiry. If you need additional assistance, do not hesitate to contact
uS.
Sincerely,

Dear Mr. Mazzullo:
Sirtett
In part 173.181(b), the requirement states, "The strong, tight metal can must be closed 260
by positive means, not by friction." Does the D.O.T. consider metal cans or
multifriction cans closed with the plastic locking rings as an acceptable method that
meets this requirement? For your information, this combination package has been
successfully pressure tested to a minimum of 95 KPA as prescribed in 178.605.
Thank you very much for your consideration, and I look forward to your response.
Very truly yours,
noWatt

The ARMLOK Transportation Ring is tested and certifled to bring our gallon through
half-pint cans into compliance with stringent shipping standards outlined in UN
Performance Oriented Packaging (HM-181 and CFA-49) guidelines. ARMLOK rings
also meet United Parcel Service and United States Postal Service requirements.
listene.
Specul
The HDPE plastic ARMLOK ring carries a U.S. Patent and is recyclable. Tasted
and cerified to meet and exceed 95-100 kPa hydroscopic pressure tests, ARMLOK
is used by manufacturers to safely transport hazardous materlals vla air, sea and
parcel service. ARMLOK rings also serve as a tamper-evident device.
Appis In
ARMLOK rings are quick and easy to apply. They reduce the potential for workers'
comp claims posed by all metal alternatives. ARMLOK can be applied by hand,
rubber mallet, Harbll press, or a roller device. High speed application methods
are being developed and your Brockway Standard Technical Support Group can
assist in set-up.
