Always wear insulated gloves when handling dry ice. Dry ice can cause freezer burns if it comes in direct contact with skin.
Store your box of dry ice in a well-ventilated area. As the dry ice sublimates (reverts from a solid to a gas) CO2 levels can build up in enclosed areas. Shortness of breath is an indication of higher than normal CO2 levels. Ensure that adequate ventilation is available at ground level.
Do not inhale the CO2 gas. CO2 is an asphyxiant. Exercise caution if reaching down into large dry ice containers. CO2 is heavier than air and builds up from ground level.
Never store dry ice in an airtight container as sublimation can result in a dangerous build-up of pressure.
Never ingest dry ice, and never place it loose into drinks. Always use ChilliSticks to safely add dry ice to drinks.
Never leave dry ice unattended around children or animals.
