Question 454 Deck General

The correct answer is C) 28°F (-2°C) and 40°F (4°C). This temperature range is typically required for the proper precooling of a reefer (refrigerated) cargo space before loading chilled reefer cargo. The cargo space needs to be cooled to a specific temperature range to ensure the cargo is maintained at the optimal temperature during transportation. Temperatures outside this range may not effectively preserve the cargo quality and freshness. The other options are incorrect because -10°F to 10°F is too cold for most chilled reefer cargoes, 12°F to 20°F is also on the colder side, and 42°F to 55°F is too warm for proper precooling and cargo preservation.
