Storage and Transport of Dry Ice
Special care should be taken when storing and transporting dry ice.
Storage
Many factors can affect the rate at which dry ice sublimes from the sold state into gaseous carbon dioxide. These include ambient temperature and humidity, the quality of the storage container, the number of times the container is opened and closed. The better the insulation, the slower the sublimation rate and the longer the quality of the product will be maintained. The list below offers suggestions for the proper storage of dry ice:
- Always store dry ice in a properly designed container
- Keep the container lid closed when not in use
- Always secure the container lid open before reaching in to unload the product. Avoid leaning into the container for longer than necessary
- Do not store dry ice in any gas tight container. Within large containers, gas atmospheres will have built up
- Do not expose dry ice to high ambient temperatures unnecessarily as this increases the sublimation rate and thereby the risk of carbon dioxide atmospheres
- Do not store dry ice in cellars or unventilated rooms
- Ensure adequate low level ventilation wherever dry ice is stored
Transport
The list below offers suggestions for the safe transportation of dry ice:
- Avoid transporting dry ice in the cab of a truck or the passenger compartment of a car. If this is not possible, the load should be well insulated and adequate ventilation must be maintained
- It is preferable to transport dry ice in vehicles where the driver's cab is isolated from the load compartment
- Always secure the load compartment doors in the open position before entering. For large "walk-in" load compartments, the doors should be capable of being opened from the inside
- Always ensure that there is adequate ventilation during transportation and before entering the load compartment to unload the product
- Always carry Carbon Dioxide (solid) Safety Data Sheet in the cab or driver's compartment of any vehicle carrying dry ice
- Always unload the product as soon as possible at the end of the journey and move it to a suitable storage location
Containers
Specially designed containers are required for dry ice storage and transport. Containers and their corresponding transport pallet are available for rental from BOC. The table below shows the different types of containers that are available:
