What is the maximum amount of dry ice that may be carried in the cabin area per person?

The correct amount of dry ice that may be carried in the cabin area per person is 5.5 pounds. This limit is established based on safety regulations concerning the use and storage of dry ice, which is solid carbon dioxide. The primary concern is that dry ice sublimates into carbon dioxide gas, which can displace oxygen in the cabin and potentially lead to hazardous situations if not properly managed.

The 5.5-pound limit serves to mitigate the risk of elevated carbon dioxide levels, ensuring that there is enough ventilation and that the overall safety of the cabin environment is maintained. Exceeding this limit could pose a danger to passenger safety due to asphyxiation risks, making adherence to this guideline essential.

Understanding this standard is crucial for anyone involved in aviation safety and operations, as it highlights the importance of regulating hazardous materials even in small quantities.
