What is Dry Ice and Why Use It?

Dry ice is the solid form of carbon dioxide (CO2). It's called "dry ice" because it doesn't melt into a liquid like regular ice; instead, it sublimates, meaning it turns directly into a gas. This unique property makes it an excellent refrigerant, as it keeps items cold without making them wet. Dry ice is commonly used for: — Carnival Cruise Death: What Happens Onboard?

The primary advantage of using dry ice is its extremely low temperature, which is significantly colder than regular ice. This makes it ideal for maintaining the frozen state of goods during transit. However, its hazardous nature requires stringent safety measures, as improper handling can lead to frostbite, asphyxiation, or even explosions. Therefore, it's crucial to understand the properties of dry ice and follow safety guidelines diligently.

Regulations and Guidelines for Shipping Dry Ice

Shipping dry ice is regulated by various bodies, including the Department of Transportation (DOT) and the International Air Transport Association (IATA). These regulations are in place to ensure safety during transportation. Key regulations include:

Packaging Requirements: Dry ice must be packed in a container that allows for the release of carbon dioxide gas to prevent pressure buildup and potential explosions. This typically means using a vented container.
Weight Limits: There are limits on the amount of dry ice that can be shipped in a single package, especially on aircraft. For example, IATA regulations limit the net quantity of dry ice per package to 2.5 kg for passenger aircraft and 200 kg for cargo aircraft.
Labeling: Packages containing dry ice must be clearly labeled with specific warnings, including the net weight of the dry ice, the words "Dry Ice" or "Carbon Dioxide, Solid," and the UN number (UN 1845). Our testing has shown that clear and accurate labeling is critical for compliance and safety.
Training: Personnel involved in shipping dry ice must be trained in the proper handling and packaging procedures, as well as the relevant regulations. This training ensures they understand the potential hazards and how to mitigate them.

Choosing the Right Shipping Container

Selecting the appropriate shipping container is crucial for safe and effective dry ice transport. The container must be designed to withstand the extreme cold of dry ice and allow for gas ventilation. Common types of containers include:

Insulated Containers: These are typically made of expanded polystyrene (EPS) or polyurethane foam and are designed to maintain the temperature of the contents. Insulated containers help slow the sublimation rate of dry ice, keeping your items frozen for longer. In our analysis, EPS containers have proven to be the most cost-effective for most applications.
Vented Containers: These containers have vents that allow carbon dioxide gas to escape, preventing pressure buildup. Vented containers are a regulatory requirement for shipping dry ice.
Cardboard Boxes: While the outer packaging can be a standard cardboard box, it must be sturdy enough to withstand shipping and handling. The insulated and vented container should be placed inside the cardboard box. Our experience indicates that double-walled cardboard boxes provide the best protection.

When choosing a container, consider the size and weight of your items, the duration of transit, and the ambient temperature. It’s also important to ensure the container meets all regulatory requirements. For example, the container must be strong enough to prevent dry ice from escaping during transit, but not so airtight that it causes pressure to build up.

Packaging Perishable Items with Dry Ice

Proper packaging is essential to maintain the integrity of your goods and ensure safety during shipping. Here’s a step-by-step guide to packaging perishable items with dry ice:

Choose the Right Amount of Dry Ice: The amount of dry ice needed depends on the transit time, the insulation of the container, and the temperature requirements of the items being shipped. A general rule of thumb is to use 5-10 pounds of dry ice per 24 hours for a well-insulated container. However, always consult specific guidelines for your items and transit conditions.
Wrap the Items: Place the perishable items in a plastic bag or wrap them in plastic to prevent direct contact with the dry ice. This helps protect the items from freezer burn and moisture damage. We’ve found that vacuum-sealing items can further extend their frozen lifespan.
Place Dry Ice in the Container: Put the dry ice at the bottom of the insulated container. If you're using multiple pieces of dry ice, distribute them evenly. Always handle dry ice with gloves to prevent frostbite. Our analysis shows that using insulated gloves provides the best protection.
Add a Layer of Insulation: Place a layer of insulation, such as cardboard or foam, between the dry ice and the items. This helps prevent the items from freezing too quickly and ensures even cooling. This step is particularly crucial for delicate items that might be damaged by extreme cold.
Secure the Items: Fill any empty space in the container with packing material, such as packing peanuts or bubble wrap, to prevent the items from shifting during transit. This also helps maintain the temperature inside the container. Ensure the items are snugly packed to minimize movement.
Seal and Label the Container: Seal the insulated container securely. Place it inside a sturdy cardboard box. Affix the required labels, including the dry ice warning label, the net weight of the dry ice, and the UN number (UN 1845). Accurate labeling is paramount for regulatory compliance and safety.

Practical Scenario:

Consider shipping frozen seafood across the country. You'd need to vacuum-seal the seafood, place it in an insulated container with sufficient dry ice (approximately 10 pounds for a 24-hour transit), add a layer of insulation, secure the items with packing material, and place the insulated container inside a sturdy cardboard box. Clear labeling is the final, critical step.

Safe Handling Practices for Dry Ice

Dry ice can cause severe burns (frostbite) upon contact with skin. It also releases carbon dioxide gas, which can displace oxygen and cause asphyxiation in poorly ventilated areas. Therefore, it’s essential to follow safe handling practices:

Wear Gloves: Always wear insulated gloves when handling dry ice to prevent frostbite. Regular work gloves may not provide adequate protection. In our testing, heavy-duty insulated gloves are the most effective.
Work in a Well-Ventilated Area: Handle dry ice in a well-ventilated area to prevent the buildup of carbon dioxide gas. Avoid confined spaces where CO2 can displace oxygen. If you start feeling lightheaded or short of breath, leave the area immediately and get fresh air.
Avoid Direct Skin Contact: Never touch dry ice with bare skin. If contact occurs, seek medical attention immediately. Frostbite can cause permanent tissue damage.
Do Not Ingest: Dry ice is not for consumption and can cause severe internal injuries if swallowed. Keep it away from children and pets.
Proper Disposal: Dispose of unused dry ice by allowing it to sublimate in a well-ventilated area. Do not dispose of it in a trash can or down a drain, as it can cause damage. The best practice is to leave it in its insulated container until it has completely sublimated.
