As a general guide, under which condition should hygroscopic cargoes be ventilated?

🔍 Key Concepts

• Hygroscopic cargoes absorb moisture from the surrounding air • The relationship between dew point, air temperature, and condensation on cargo • The rule of thumb: "ventilate with drier air, close when outside air is more humid"

💭 Think About

• Think about what happens if warm, moist air enters a hold with cooler cargo. Where will moisture go and when will it condense? • Compare the dew point of the air in the hold to the dew point of the outside air. In which case is the outside air actually drier? • Ask yourself: Is the goal to remove moisture from the cargo/hold, or could ventilation actually add moisture to a hygroscopic cargo?

✅ Before You Answer

• Compare dew point inside vs outside: which condition means the outside air can absorb more moisture? • Remember that dew point, not just temperature, controls whether condensation will form on the cargo surface. • Verify which options describe a situation where ventilating would likely increase condensation risk on cooler hygroscopic cargo rather than reduce it.

Question 1 of 27070

As a general guide, under which condition should hygroscopic cargoes be ventilated?

When the dew point of the air in the hold is very low

When the outside dew point is 60°F (16°C) and the cargo temperature is 54°F (12°C)

When the dew point of the outside air is greater than the dew point of the air in the hold

When going from a warm to a cold climate
