Subsection 5.0.1.5-5.0.2 - Packing Requirements

Dangerous goods in Classes 3 and 4, Divisions 5.1 and 6.1, Class 8, and some Class-9 substances are assigned to one of three packing groups according to the relative degree of danger presented by the substance. Packing Group I is for substances presenting the highest degree of danger and, therefore, has the strictest requirements. Packing Group II is for substances presenting a medium degree of danger, and Packing Group III is for substances presenting a low degree of danger.

Overpacks

An overpack is an enclosure used by a single shipper to contain one or more packages. It forms one handling unit for convenience in handling and stowage. Each dangerous goods package within an overpack must be properly packed, marked, and labeled according to these Regulations.It should be noted, however, that an overpack may contain packages of goods that are not subject to these Regulations.

Salvage Packagings

Salvage packagings are special packagings for damaged, defective, leaking, or non-conforming dangerous goods that need to be transported for recovery or disposal. Salvage packagings must meet the requirements of 5.0.1.6.2 and 6.7, and to be shipped, they require prior approval from the appropriate national authority.
