Dear Mr. Rousseau:
This responds to your February 23, 2004 letter on behalf of PPG Industries, Inc., concerning the transportation of calcium hypochlorite, hydrated, UN 2880, under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if calcium hypochlorite, hydrated, UN 2880, transported in 300- and 425-lb. fiber drums, is a forbidden material within the meaning of § 173.21 of the HMR.
The answer is no. Notwithstanding that the self-accelerated decomposition temperature (SADT) of calcium hypochlorite, hydrated, UN 2880, in the drums is slightly less than 50 EC, the material is not forbidden under § 173.21 because the material is not likely to decompose under normal conditions of transport when shipped in accordance with applicable regulatory requirements. Under the HMR, calcium hypochlorite, hydrated, UN 2880, is not subject to the controlled temperature provisions of § 173.21(f) when transported in the quantities and packagings specified in your letter. All applicable HMR requirements for shipping documentation, packaging, marking, labeling, placarding, and stowage and segregation must be met. Similarly, calcium hypochlorite, hydrated, UN 2880, is not a prohibited material or subject to temperature control requirements under the provisions of the international Maritime Dangerous Goods (IMDG) Code. Under both the HMR and the IMDG Code, calcium hypochlorite, hydrated, UN 2880, is subject to stowage provisions that require it to be stowed away from heat.
I hope this information is helpful. Please let me know if you have questions or require additional information.
Sincerely,
Edward T. Mazzullo
