Ref. No. 13-0089
Dear Mr. Galante:
This responds to your letter requesting clarification of the Hazardous Materials Regulations
(HMR; 49 CFR Parts 171-180) applicable to aerosols. In your letter, you state that one of
your clients recently became aware that R -134a aerosol refrigerant recharge product was
being shipped in Department of Transportation (DOT) Specification 2Q containers exceeding
180 psig at 130 °F. You ask whether the pressure in a DOT Specification 2Q container may
exceed 180 psig at 130 °F.
The answer is no. The pressure in a DOT Specification 2Q container may not exceed 180
psig at 13 0 °F. Exceptions to this requirement may be authorized under the terms and
conditions prescribed in a DOT special permit. A container authorized under a special permit
bears a "DOT -SPXXXXX" mark in lieu of a "DOT 2Q" mark. You may wish to inform your
client that they may file a complaint with our enforcement office at the following link:
http:/ /v..rww.phmsa.dot.gov /phmsa-cxt/fced back/hazr.JatComplaintsRcg_sV iolationsFonn. j sp .
I trust this satisfies your inquiry. Please contact us if we can be of further assistance.

Re: Automotive Refrigerant Product in DOT 2Q Containers
Dear Mr. Betts:
I represent manufacturers and distributors of automotive servicing products. In late 2012,
one of my clients became aware that R-134a aerosol refrigerant (R-134a) recharge products were
being shipped in 2Q cans.
To our knowledge the regulations specified in 49 CFR 173.306(a)(3)(ii) only allows a 2Q
metal container when the pressure does not exceed 180 psig at 130° F. Also to our knowledge,
the only method to ship the materi~l in question is by the use of a Special Permit (ref. SP10232,
SP14188 and SP14286). ..
We have also recently noticed that certain vendors are currently using 2Q metal
containers for limited quantity gases which exceed the 180 psig limit. If the industry were
allowed to use the 2Q metal container, the benefit would be that the 2Q container is more readily
available and less expensive than the containers authorized under the various Special Permits.
This issue is very important to my client. We respectfully request a Letter of
Interpretation on this question from D.O.T. so that there can be no further confusion about
whether shipping R-134a products that exceed 180 psig at 130° Fin 2Q cans is permissible.
Very truly yours,
fie'vul ~
