Is dry ice permitted to be used as ice to keep beverages cold onboard?

Dry ice is not permitted for use on board aircraft as a means to keep beverages cold due to safety regulations. The main concern with dry ice is that it sublimates into carbon dioxide gas, which can displace oxygen in enclosed spaces, potentially leading to suffocation risks. Additionally, dry ice can cause burns if it comes into direct contact with skin, posing a risk to passengers and crew alike.

Regulatory bodies prioritize passenger safety and have established guidelines prohibiting the use of dry ice in this context. This rule ensures that onboard environments remain safe and breathable, avoiding any hazards associated with high concentrations of carbon dioxide or the physical dangers associated with handling dry ice. Therefore, beverages should be kept cold using conventional ice or other approved cooling methods that do not pose safety risks.
