What is the maximum allowable dry ice load on Delta Airlines per package?

The correct answer of 5.5 lbs per package reflects compliance with regulations concerning the transport of dry ice, which is classified as a hazardous material due to its ability to produce carbon dioxide gas when it sublimates. This quantity is designated to mitigate risks associated with excessive carbon dioxide concentrations in the aircraft cabin and cargo areas, which can be hazardous to both passengers and crew.

By limiting the dry ice load to 5.5 lbs per package, Delta Airlines adheres to safety regulations that ensure a safe operating environment. This threshold is designed to strike a balance between allowing the shipment of perishable goods requiring dry ice while maintaining safety standards. Other choices exceed this limit and would likely pose risks that could lead to regulatory non-compliance and safety hazards onboard.
