Which statement is true about maximum quantities of dry ice in compartments?

• A. Maximum quantities are specified per compartment
• B. There is no limit
• C. Dry ice is prohibited
• D. Only one per aircraft

Answer: (A)

The main idea here is that safety limits for dry ice are set for each space inside the aircraft, not just once for the whole plane. Dry ice sublimates to carbon dioxide, which can accumulate in a confined compartment and displace oxygen or create pressure issues. Because each compartment has different size, ventilation, and surroundings, the allowed amount of dry ice is defined for that specific space. This per-compartment approach lets handlers balance the cargo’s needs with the aircraft’s ventilation and structural limits, and the total amount carried on a flight is the sum of the limits for all compartments used. Therefore, the true statement is that maximum quantities are specified per compartment.
