What action must be taken when humidity indicator cards show humidity over 50 percent?

• A. Increase ventilation
• B. Desiccant must be replaced with fresh material
• C. Seal the area
• D. Conduct an emergency inspection

Answer: (B)

When humidity indicator cards show humidity over 50 percent, replacing the desiccant with fresh material is crucial because excessive humidity can compromise the integrity of stored components or materials sensitive to moisture. Desiccants are used to absorb moisture from the air in a confined space, ensuring that the conditions remain dry and suitable for preservation. Once the humidity indicator card indicates a level above 50 percent, it signifies that the current desiccant has become saturated and is no longer effective at maintaining the desired dry conditions. Therefore, replacing the desiccant helps restore the moisture-absorbing capacity, preventing damage or degradation of items that require low humidity environments. Increasing ventilation, sealing the area, or conducting an emergency inspection might address humidity issues temporarily or in specific scenarios, but they do not directly remediate the problem of excessive moisture as effectively as replacing the desiccant does.
