Shipper notes
UN1845 Carbon dioxide, solid or Dry ice
- Excepted from most 49 CFR requirements by highway and rail under 173.217 when used as a refrigerant for a non-hazardous material; the air rules under IATA packing instruction 954 still apply and require the net quantity in kilograms on the package.
- The packaging must vent carbon dioxide gas — a sealed package is a rupture hazard.
