Pack dry ice into a ventilated insulated container (camping coolers are perfect) to slow down it's melting process.
Dry Ice must be ventilated so it doesn't build up pressure as it warms up and sublimates (changes from a solid to a gas).
Keep your dry ice dry by wrapping it in a plastic bag or newspaper. Water speeds up the melting process, and for this reason dry ice disappears faster on wet and rainy days.
HandlingMake sure to read the safety information.
Use gloves that won't freeze to insulate your skin when handling dry ice. Garden gloves, leather gloves, ski gloves etc., not rubber gloves.
Transportation - LAND
Dry Ice needs to be well insulated so it doesn't melt as fast while you're transporting it (see storage for more information.) The easiest solution is a camping cooler; smaller coolers hold 30-40 lbs. and large coolers hold about 100 lbs. of dry ice. Because it is extremely cold you should use gloves to handle it, garden gloves work fine, ski-gloves are good for insulation as well and rubber gloves are better then nothing but tend to freeze with more then a minute of handling.
Dry ice is classified as a dangerous good by Transport Canada and there are specific regulations to follow. For smaller amounts you need to identify the container as holding dangerous goods (a sticker works fine) and for larger amounts you need to label the entire vehicle (placards). Iceberg Dry Ice can supply you with this documentation if you need it - see the table below to determine what is needed.
|0 - 5 kg||not regulated|
|5 - 499 kg|| 1. Class 9 Sticker|
2. TDG Forms
|500 kg+|| 1. Class 9 Sticker|
2. TDG Forms
3. Placards on all 4 sides of vehicle
Transportation - AIRBelow are some commonly found guide lines but please check with the transport company itself to confirm exactly what is required.
Transportation of Dangerous GoodsDry Ice is listed as a dangerous good and should be labelled with the following information during transport.
|UN Number||UN 1845|
|Shipping Name||Carbon Dioxide, Solid OR Dry Ice|
|Special Provision 18||When used as a refridgerant, the container must be marked as such. The container must be designed and constructed to permit the release of CO2 to prevent the buildup of pressure.|
|Special Provision 81||Dry Ice should be transported in a means of containment that will prevent accidental release that could endanger public safety under normal circumstances.|
