Recent revision of Closure Instructions for all UN packagings further emphasizes the information that must be given by packaging manufacturers and distributors (Docket #HM-215E). For steel drums (CFR 178.2(c), the ‘art’ of closing a steel drum must be translated into a technical procedural instruction. The DOT has now stated that Closure Instructions are to include the types and dimensions of closures, including gaskets, needed to ensure (note emphasis) that the packaging is capable of passing the applicable performance tests. The instructions must also include any procedures to be followed, for inner packagings, to effectively assemble and close the package to prevent leakage in transportation.
