The Journal of HazMat Transportation's™ Exclusive Comments on U.S. DOT Letters of Interpretation of the HMR

摘要

To read the PHMSA letter, please go to page 60 of the July/August 2021 edition of the Journal. In this letter, the requester is using a large 133 cubic foot (ft~3 ), shielded Type A package for low specific activity (LSA) material that exceeds a Type A activity limit. His questions are specific to this situation as well as other scenarios where the activity does not exceed Type A. First, it's important to recognize that the shipper has determined the package used meets the definition of a bulk package, or is an undefined package (neither bulk or non-bulk) but has elected to ship it as if it were a bulk package. Refer back to our January/February 2014 issue, p. 38 for a discussion of bulk and non-bulk packagings as applied to radioactive material.
