Reference No. 22-0049
Dear Mr. Stephens:
This letter is in response to your April 14, 2022, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the segregation of hazardous materials when transported by vess Mike Stephens el. Specifically, you seek confirmation that your understanding of § 176.83(a)(8) is accurate in that a Division 2.3 (Gas poisonous by inhalation) hazardous material with subsidiary hazards of Division 2.1 (Flammable gas) and Class 8 (Corrosive) may—under certain conditions—be stowed in the same cargo transport unit on board a vessel as a Division 2.3 gas with a subsidiary hazard of Class 8.
Your understanding is correct. In accordance with § 176.83(a)(8) and notwithstanding the requirements of paragraphs (a)(6) and (a)(7) of § 176.83, hazardous materials of the same class may be stowed together without regard to segregation required by secondary hazards—subsidiary risk label(s)—provided the substances do not react dangerously with each other and cause: 1) combustion and/or evolution of considerable heat; 2) evolution of flammable, toxic, or asphyxiant gases; 3) the formation of corrosive substances; or 4) the formation of unstable substances.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
T. Glenn Foster
Chief, Regulatory Review and Reinvention Branch
Standards and Rulemaking Division
