O. Box 808, L-668 Livermore, CA 94550 Dear Mr. Thomas: This responds to your letter requesting clarification on authorized packaging for poison inhalation hazard (PIH) materials under § 173.226(c)(2) of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Your questions are paraphrased and answered as follows: Q1. We offer for transportation Division 6.1, PG I, Hazard Zone A materials in an inner packaging system consisting of three inner packagings; the HMR prescribe two inner packagings. We place a single one liter non-impact resistant glass receptacle in an impact- resistant packaging with compatible absorbent material. This in turn is placed into a leak- tight packaging, again with compatible absorbent material, that is packed within an outer 4G fiberboard box. The completed inner packaging system meets the performance standards at the PG I level in subpart M, part 178, of the HMR. Does this packaging meet the requirements in § 173.226(c)(2)? Al. The answer is yes. Even though you have an additional inner receptacle, your packaging meets the provisions in $173.226(c)(2). The capacity of each inner receptacle may not exceed 4 L (1 gallon). Both the inner packaging system and the outer packaging must meet the performance test requirements in subpart M, part 178, of the HMR. Q2. Under the provisions in §173.226(c)(2), may multiple inner impact-resistant glass receptacles containing Division 6.1, PG I, Hazard Zone A materials be packed into the leak-tight intermediate packaging? A2. Section 173.226(c)(2) authorizes multiple impact-resistant inner receptacles, provided the capacity of each inner receptacle does not exceed 4 L (1 gallon), and the total amount of 173,226 030170 <<>> liquid contained in the outer packaging does not exceed 16 L (4 gallons). Additionally, the inner packaging system and the outer packaging must conform to the performance test requirements in subpart M, part 178, of the HMR. I hope this satisfies your inquiry.

The purpose of this correspondence is 1) To obtain written concurrence to the guidance that Mr. Satterthwaite provided us on December 18, 2002 and 2.) To pose an additional question (to your department) that is also related to 49 CFR 173.226 (c)(2). First, during our December 18 phone conversation, Mr. Satterthwaite concurred with me that placement of inner-glass containers (holding materials meeting the definition of division 6.1 PGI, Zone A inhalation-hazard [PIH]) into non-breakable intermediate containers meets the "impact- resistant glass" requirement, provided that the following conditions are met: • The intermediate container is compatible with the lading. • Movement of the inner-glass container is restricted within the intermediate packaging via a compatible absorbent medium or other appropriate dunnage. • The final inner packaging system conforms to the performance test requirements of 4 FR 178 Subpart M, at the Packaging Group I level. See Illustration / breakable containers) preserves the intent of the regulation and provides much needed relief t VI. Satterthwaite's interpretation (of conditionally allowing the use of intermediate non the regulated community. However, before implementing this guidance, we are requesting a expressed position. written response from the Office of Hazardous Materials Standards, reiterating the previously An Equal Opportunity Employer • University of California • P.O.
