Dear Mr. Conway:
This responds to your letter dated December 21, 2005,
regarding the packaging of toxic by inhalation liquids
under the Hazardous Materials Regulations (HMR; 49 CFR
Parts 171-180). Specifically, you ask whether liquids
described as "Toxic by inhalation liquid, corrosive,
n.o.s., 6.1, UN3390, PG I, 8" may be transported in an
insulated DOT 412 cargo tank motor vehicle.
The answer is yes.
The cargo tanks authorized for a Zone B
inhalation hazard material (UN3390) are found in § 173.244
of the HMR, as limited by the applicable special provisions
of § 172.102. As prescribed in § 173.244 (b),
a DOT 412
cargo tank is authorized for a Zone B
inhalation hazard
material (UN3390). In accordance with Special Provision
B14, the cargo tank must be insulated.
I trust this satisfies your inquiry.
Please contact us if
we can be of further assistance.
Sincerely,
tille = nitate

Re: Request for Formal Interpretation or Formal Guidance
I have a question regarding the bulk hauling of Telone C35 (EPA Reg. No 62719-302).
Telone C35's new UN number effective January 1, 2006 is UN3390. I have confirmed
this with the marlufacturer, Dow AgroSciences, LLC. Telone C35 is 63.4% 1,3
dichloropropene, 34.7% chloropirin, and 1.9% inerts. Reviewing CFR 49 Hazardous
Material Rules itiappears that C35 can be hauled in bulk using insulated DOT 412 cargo
tanks that contorm to the special provisions in section 172.102 and packaging rules in
173.227 and 244; Is this correct?
I spoke with a hazardous materials regulatory specialist at the Hazardous Materials
Information Center. He said my conclusion was correct. I am looking for a written
formal interpretation or formal guidance.
Thank you in advance for your cooperation.
Mike Conway
General Manager
