If operating with an unpressurized flight, what is your directive regarding dry ice shipments?

When considering the handling of dry ice shipments during unpressurized flight operations, safety protocols are of utmost importance. Dry ice, being solid carbon dioxide, can sublimate to carbon dioxide gas, which poses risks in confined or unventilated areas where the gas could accumulate, potentially leading to asphyxiation or other hazards.

In unpressurized environments, the risk is significantly higher because the lack of pressure can exacerbate the accumulation of gases. The directive to prohibit any shipments of dry ice in these conditions is rooted in the need to prevent dangerous scenarios from occurring.

Other options, such as notifying the cargo department or limiting shipments, do not adequately address the inherent risks associated with unpressurized flight and dry ice, as they could still allow for conditions where hazardous situations might develop. Therefore, prohibiting shipments ensures that safety is prioritized, preventing any chance of exposure to potentially harmful concentrations of carbon dioxide gas.
