What method should be utilized for wet, pooled liquids that may damage cargo?

The most appropriate method for addressing wet, pooled liquids that could potentially damage cargo is a hot high-pressure wash. This technique is effective because it combines the force of high-pressure water with heat, which helps to thoroughly clean the area and break down any substances that may be present. The heat from the water aids in evaporating any residues, ensuring that the pooled liquids are completely removed.

Using a hot high-pressure wash is particularly beneficial in situations where contaminants are not only present on the surface but might also require deeper cleaning to prevent damage to the cargo. It allows for a more effective cleaning process compared to a cold wash, which may not adequately address stubborn substances or ensure a completely dry environment, increasing the risk for any cargo in the container.

The other options do not provide the same level of effectiveness for dealing with pooled liquids. Cold washing lacks the benefit of heat, which is crucial in breaking down residues. Sweeping may only remove loose debris and leaves behind liquids that could still pose a risk to the cargo. Choosing "no repair" isn't a viable solution for maintaining cargo integrity, as it allows damaging conditions to persist. Therefore, utilizing a hot high-pressure wash is the best course of action to mitigate the risk effectively.
