Dear Mr. Mahoney:

This is in response to your letter dated January 6, 2000, regarding stowage requirements for foodstuffs and corrosive liquids under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  Specifically, you ask if a foodstuff which is also a Class 3 hazardous material may be stowed with a Class 8 corrosive liquid in the same freight container or transport unit.

The answer is yes.  Section 176.800(a) states that each package requiring a Class 8 (Corrosive) label must be stowed clear from living quarters and away from foodstuffs.  Section 176.83(c)(2)(ii) defines Aaway from@  to mean a minimum horizontal separation of three meters (10 feet) projected vertically.  Your foodstuff is also a Class 3 hazardous material; however, § 176.83(b) does not require segregation between Class 3 and Class 8 materials.  Therefore, the only segregation requirements you must meet are those of ' 176.800(a).

Corrosive materials must be effectively segregated from foodstuffs so that they cannot react dangerously in the event of an accident but may be stowed in the same freight container provided a minimum horizontal separation of three meters (ten feet) inside the container is obtained.

I hope this satisfies your request.

Director, Office of Hazardous
Materials Standards
