Safe Handling and Storage of Dry Ice
NEVER leave Dry Ice unattended around
- The temperature of Dry
Ice is extremely cold at -109 °F or -78°C.
- Do not allow Dry Ice to
touch bare skin. Dry Ice in contact with skin may result
in frostbite. Prolonged exposure will cause severe frostbite.
- Always wear protective
gloves whenever handling Dry Ice.
- Children must not handle
Dry Ice. Adults must never leave Dry Ice in the possession
- Dry Ice will sublimate
into Carbon Dioxide (CO2) gas.
- Store Dry Ice in an insulated
container - the better the insulation, the slower the Dry
Ice sublimation. Do not store Dry Ice in a refrigerator
or a freezer (unless the Dry Ice is being used to maintain
the proper holding temperature).
- Do not store Dry Ice
in an airtight container; never store in a glass container.
The sublimation of Dry Ice into Carbon Dioxide gas will
cause an airtight container to expand, rupture or burst.
- Always store Dry Ice in
a well ventilated area. Avoid storing Dry Ice in unventilated
rooms, cellars, autos or boat holds. The sublimated Carbon
Dioxide gas will sink to low areas and replace oxygenated
air. Carbon Dioxide gas at elevated concentrations may be
fatal when breathed.
- Some surfaces left in
direct contact with Dry Ice may be damaged by the extreme
cold. Adhesives may become brittle and break.
- Air is composed of 78%
Nitrogen, 21% Oxygen and only 0.035% Carbon Dioxide (CO2).
If the concentration of CO2 in the air rises above 0.5%,
it can become dangerous. Lower concentrations - i.e. below
0.5% - can cause accelerated, laboured breathing and headache.
- If Dry Ice has been in
a closed auto, van , room , or walk-in refrigerator for
more than 10 minutes, open doors and allow adequate ventilation
before entering. Leave the area immediately if breathing
becomes difficult, or if dizziness, headache or light-headed
feeling is noticed.
- Carbon Dioxide (CO2) is
heavier than air and will accumulate in low spaces.
- Do not enter closed Dry
Ice storage areas without first fully ventilating the space.
Pick-up and transportation instructions
- Plan to pick up the Dry
Ice as close as possible to the time it is needed.
- Bring a well-insulated
container such as a camping cooler or an ice chest.
- If it is transported
inside a car or van, make sure there is a constant supply
of fresh air.
