Protective gloves
Use suitable insulated protective gloves when handling dry ice. Avoid direct skin contact and protect eyes from chips or fragments where the task creates that risk.
Ventilation and carbon dioxide
Dry ice sublimates directly into carbon dioxide gas. Maintain adequate ventilation and do not allow carbon dioxide to accumulate in occupied or poorly ventilated spaces.
Never use a sealed airtight container
Sublimation can cause pressure to build inside an airtight container. Use packaging and storage arrangements designed for dry ice and its gas release.
Storage
Store dry ice in a suitable insulated container in an appropriate, ventilated location. A domestic freezer does not stop sublimation.
Vehicle transport
Plan vehicle transport to account for carbon dioxide gas release, ventilation, securing of packages and the receiving window. Do not treat a closed passenger compartment as a general-purpose dry ice storage space.
Children and untrained users
Keep dry ice away from children and anyone who has not been instructed in safe handling.
Sublimation and disposal
Allow residual dry ice to sublimate in a controlled, secure and well-ventilated location where people and animals cannot contact it. Do not dispose of dry ice in sealed waste containers.
