The Hidden Risks of Dry Ice: Why Dry Ice May Not Be the Best Choice for Your Lab’s Temperature-Controlled Shipments

The Hazards of Dry Ice for Safe Shipping

Dry ice is a popular cooling solution in shipments, thanks to its extreme cold temperature of -80°C, but it also brings significant risks, impacting not just safety but the timing and integrity of the transported specimens.

The Health Risks of Carbon Dioxide Buildup

As solidified carbon dioxide (CO₂), dry ice sublimates directly from a solid to a gas. In areas with poor ventilation, CO₂ gas can accumulate, quickly reducing oxygen levels in the air. 

This can lead to serious health hazards such as breathing difficulties, unconsciousness, and in severe cases, even death. Handling dry ice without gloves is also dangerous due to its extremely cold temperature, which can cause severe frostbite.

Strict Airline Guidelines for Dry Ice Packaging

Airlines implement stringent guidelines to mitigate these risks. Each package containing dry ice can hold a maximum of 2.5 kilograms (5.5 pounds), and all containers must be ventilated to allow CO₂ gas to escape safely. 

However, these safety measures also introduce added costs and delays in shipping. Shipments may be postponed or incur additional surcharges due to airline limits on the total dry ice allowed per aircraft.

Impact on Temperature-Sensitive Lab Specimens

Lab specimens are often highly sensitive to temperature changes, and any obstacles—such as delays, improper handling, or sub-zero exposure from dry ice—can lead to temperature excursions. Such incidents can make specimens unusable, requiring re-collection and reshipment, delaying results, and ultimately impacting patient outcomes.
