TRANSPORTING BY AUTO OR VAN
Plan to pick up the Dry Ice as close to the time it is needed as possible. If
possible pack insulating items such as sleeping bags around the ice chest. This
will stretch the time that the Dry Ice lasts. If it is transported inside a car
or van (not in the trunk) for more than 10 minutes make sure there is fresh air.
After 15 minutes with Dry Ice only in its paper bag in the passenger seat next
to me, I started to breathe faster and faster as though I were running a race. I
couldn't figure out why I was so out of breath until I saw the car air system
was set in the re-circulated position, not fresh outside air.
TRANSPORTING BY AIRPLANE
Pick up Dry Ice as close to departure time as convenient. Carry it in a
well-insulated container such as an ice chest or insulated soft pack. If it is
transported inside a car or van for more than 10 minutes make sure there is
fresh air available. Most airlines will not let you carry more than two
kilograms (4.4 pounds) of Dry Ice on the airplane. Because Dry Ice will
sublimate continuously from the time of purchase, you can confidently declare
that there is no more than two kilograms at the time you check in at the
airport. If the container is checked in as baggage and not carried on board, it
will sublimate faster due to the lower pressure of the baggage compartment. Make
plans to refrigerate or add Dry Ice when arriving at your destination.
