Handling, Storage, and Transport of Dry Ice

Proper handling, storage, and transport of dry ice are essential to ensure safety and maintain its effectiveness. Dry ice should be handled using insulated gloves and tongs to avoid direct skin contact.
Dry ice should be stored in well-ventilated areas to prevent the buildup of CO2 gas, which can displace oxygen and pose a suffocation hazard. It should also be stored in insulated containers, but these containers should not be airtight, as the sublimation of dry ice can cause pressure buildup and a potential explosion.
Most containers for dry ice storage and transport are made of foam or polyethylene with urethane foam insulation.
Dry ice must be packaged during transport in accordance with the regulations for transporting hazardous materials, which include proper labeling and documentation.
