As dry ice sublimates, it turns back into CO2 gas. In small amounts, CO2 is harmless, but in larger quantities it can lead to shortness of breath or even asphyxiation. Because of this, it is important to always use dry ice in a well-ventilated area. If dry ice has been stored in a room or vehicle for more than 10 minutes, you must open a door or window and allow adequate ventilation. Note: If you working with or near dry ice and suddenly find you are having difficulty breathing or are out of breath, open any nearby windows and vacate the area for at least 10-15 mins.
Dry Ice is extremely cold at a temperature of -78.5°C (-109.3°F). Touching dry ice with unprotected skin can lead to freeze burns or even frostbite. The severity of the burn depends on the duration of contact with the dry ice. Always use gloves (preferably insulated) or protective cloth when handling dry ice. If gloves are not available, a towel or oven mitts will suffice.
Dry ice is capable of causing serious internal injury if ingested. In case of ingestion, consult a medical professional immediately.
Dry ice should be stored in an insulated container. This will reduce the rate of sublimation, making your dry ice last longer. Ensure that the container is not completely airtight, the sublimation of dry ice to CO2 gas will cause an airtight container to expand or possibly explode. As a result of this, a certain amount of CO2 will inevitably enter whatever room you are using to store the dry ice. Hence the importance of keeping your storage room well-ventilated.
How long does dry ice last?
10kgs of dry ice stored in the small Polar Ice storage carton will last for up to 72 hours from the time you receive it. However, for best results, you should use the dry ice within 48 hours of receiving it.The more dry ice you have stored in the container, the longer it will last. This means it’s important to have a delivery as close as possible to the time you will need the dry ice. Refrain from opening and closing the insulated container as much as possible. When you remove product from the container fill the empty space with wadded newspaper or styrofoam sheets. Any “dead-air-space” will cause the dry ice to sublimate faster.
How should I dispose of dry ice?
When finished with your dry ice, unwrap it and leave it at room temperature in a well-ventilated area. It will sublimate from a solid to a gas. Due to the CO2 released by the sublimation process, ensure that the dry ice is kept clear of people and animals.
NEVER leave dry ice unattended around children or animals
