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,

Hattie L. Mitchell
Chief, Regulatory Review and Reinvention
Office of Hazardous Materials Standards
