🔍 Key Concepts

• Dew point and condensation – moisture will condense on a cold surface if the air in contact has a higher dew point than that surface • Sweating of cargo/ship’s sweat – how and where condensation forms when warm moist air meets cooler cargo/steel • Ventilation decisions – when outside air is more or less humid than hold air, and how this affects whether you should ventilate

💭 Think About

• If the outside air has a higher dew point than the hold air, what does that say about the moisture content (absolute humidity) of the outside air compared to the hold air? • What happens to cargo and steel surfaces when you bring in air that contains more moisture than the air already in the hold? Think about whether this increases or decreases the risk of condensation on the cargo. • In this situation, would you want to increase the exchange of air between outside and hold, or minimize it, to protect hygroscopic (moisture‑sensitive) cargo?

✅ Before You Answer

• Compare which air mass is more humid: higher dew point = more moisture in the air. • Decide whether bringing in outside air will add moisture to or remove moisture from the hold atmosphere. • Check which answer choice corresponds to avoiding the introduction of more humid air into the cargo hold.
