Which factor is MOST important in preventing sweat damage within a cargo hold?
• Cargo sweat vs. ship sweat and how each forms • Role of dew point in condensation inside cargo holds • How outside air entering the hold can cause or prevent condensation
• First, recall what has to happen for sweat (condensation) to appear on cargo surfaces inside a hold. • Ask yourself: when you ventilate a hold, which property of the air really determines whether moisture will condense on colder surfaces? • Think about whether the temperature alone, or the moisture content of the air (expressed as dew point), is the controlling factor in forming sweat inside the hold.
• Identify which option refers to moisture content of air rather than just temperature. • Decide whether the critical location for condensation risk is inside the hold or in the air being brought in from outside. • Check which choice would be used in practice to decide whether to ventilate or keep the hold closed to avoid sweat damage.
