Requirements for the Packaging and Transport of Pathology Specimens and Associated Materials 3rd Edition

Appendix G - Transporting dry ice by air (Normative)

Page last updated: 22 October 2012

Substances being packed for transport by air with dry ice as a refrigerant must be packed by an employee trained to pack dry ice. Training is obtained by successfully completing an accredited course.

Dry ice when transported by any mode (e.g. air, road, rail), must be in packaging designed and constructed to permit the release of carbon dioxide gas and to prevent build-up of pressure that could rupture the packaging.

IATA Packing Instruction 904 must be followed.

The shipper and operator(s) must ensure that the following ventilation safety procedures are followed:

  1. The dry ice must be placed outside the secondary packaging, and interior supports must be provided to keep the secondary packagings in the original position after the dry ice has dissipated
  2. The outer packaging must permit release of carbon dioxide gas that could rupture the packagings
  3. The outer packaging must be marked and labelled with:
  • DRY ICE
  • UN 1845
  • the weight of the dry ice in kilograms
  • miscellaneous IATA hazard label (Class 9) (see Figure 3.1).

Documentation

Information about dry ice is only required on a shipper’s declaration when the dry ice is used as a refrigerant for dangerous goods that require a shipper’s declaration (e.g. dry ice as a refrigerant for Infectious Substances, Category A). When a shipper’s declaration is not required (e.g. for Biological Substances, Category B), the following information about dry ice must be contained in the ‘Nature and Quantity of Goods’ box on the waybill or consignment note:
  • proper shipping name (DRY ICE)
  • miscellaneous hazard label (Class 9)
  • UN 1845 mark
  • net weight of dry ice (in kilograms) in each package.
