Desiccants should be used in which of the following to prevent damage during storage?

Using desiccants in sturdy bags is effective for preventing damage during storage because sturdy bags provide a protective barrier against environmental factors while allowing for the potential moisture control that desiccants offer. Sturdy bags are typically made of materials that can withstand various elements such as impacts and rough handling, thereby ensuring that the desiccant can function effectively.

When the desiccant is placed within these bags, it absorbs moisture from the air inside, thus lowering the humidity levels and protecting the contents from corrosion and degradation that can result from excess moisture. This is particularly important for sensitive electronic components in avionics, where humidity can lead to corrosion of metal parts and failures in electrical connections.

In contrast, while the other options might offer some form of protection, they may not provide the same level of durability or moisture management. Plastic containers can trap moisture if not ventilated properly, while cardboard boxes can absorb moisture, compromising their structural integrity and allowing humidity to affect the stored items. Fabric pouches might not provide adequate protection against physical damage or external humidity levels. Thus, sturdy bags are the best option to ensure effective corrosion control during storage.
