J. Madden\nPresident\nHibrett Puratex\n700 1 Westfield Avenue\nPennsauken, NJ 081 10\nRef. No.: 09-01 57\nDear Mr. Madden:\nThis responds to your letter dated July 10,2009, regarding the stacking requirements\nunder the Hazardous Materials Regulations (HMR; 49 CFR Parts 17 1 - 180). Specifically,\nyou ask about stacking packages containing either hazardous or non-hazardous materials\non top of a skid containing four 55-gallon drums of Class 8 material.\nYour letter provides several examples of stacking configurations, as follows:\nExample 1: 4 x 55 gallon drums of a Class 8 (Corrosive) on a skid stretch wrapped\nwith 5 gallon pails or 4 x 1-gallon cases stretch wrapped on top.\nExample 2: 4 x 55 gallon drums of a Class 8 (Corrosive) on a skid stretch wrapped\nwith several 50 pound bags stretch wrapped on top.\nExample 3: 4 x 55 gallon drums of a Class 8 (Corrosive) on a skid stretch wrapped\nwith empty, new containers secured on top.\nSection 178.606 contains requirements for stacking non-bulk packagings. All non-bulk\npackaging design types other than bags must be subjected to a stacking test. The duration\nof the stacking test must be for 24 hours, except for plastic drums, jerricans, and\ncomposite packaging 6HH intended for liquids. These packagings intended for liquids\nmust be subjected to a stacking test for a period-of 28 days. When using a combination\npackaging where the outer packaging is a plastic drum or jerrican and the inner packaging\nis intended for liquids, the plastic drum or jerrican would be subject to the 24-hour\nstacking test, not the 28-day requirement (See 5 178.606(~)(1)).\nFor the purposes of periodic retesting, the stacking test may be done in accordance with\n§ 178.606(~)(1) or, as an alternative, the packaging design may be tested using a dynamic\ncompression testing machine as described under fj 178.606(~)(2)(ii). The dynamic\ncompression testing machine is only authorized for periodic retesting and may not be\n\n<<<PAGE 2>>>\n\nused when performing design qualification testing on a new packaging design type (e.g.,\n\"a different packaging\" as defined under @ 178.60 1 (c)(4)).\nProvided your non-bulk packagings, other than bags, have been subjected to the design\ntype tests and periodic retests applicable to stacking requirements, you may stack your\nproducts in the manner provided in your examples.\nI hope this information is helpful. If we can be of further assistance, please contact us.\nSincerely yours,\nCharles E. Betts\nChief, Standards Development\nHazardous Materials Standards\n\n<<<PAGE 3>>>\n\nHIBRETT PURATEX\n7001 Westfield Avenue\nPennsauken, IVJ. 081 10\nPhone 856-662-1 71 7\nToll Free 800-260-51 24\nFax 856-662-0550\nwww.hibrettpuratex.com\nFriday, July 10,2009\nU.

We have had a policy of never placing\nany cargo on top of a container of a hazmat but we have seen examples of such shipments.\nThank you!\nManufacturers & Distributors of Cleaning Compounds, Water Treatment, Swimming Pool and Industrial Chemicals","truncated":false,"body_characters":4182}
