What must be done when the humidity indicator cards show humidity levels over 50 percent?

• A. Increase ventilation
• B. Replace the desiccant with fresh material
• C. Reduce steam production
• D. Seal all openings

Answer: (B)

When humidity indicator cards display humidity levels above 50 percent, it indicates that the desiccant currently being used to control moisture has exceeded its capacity to absorb additional water vapor. In such situations, replacing the desiccant with fresh material is necessary to effectively manage and reduce humidity levels. Fresh desiccant ensures that the environment remains dry enough to protect sensitive equipment and materials, preventing corrosion and other moisture-related issues. Increasing ventilation, reducing steam production, or sealing all openings may be effective in specific circumstances, but they do not directly address the core issue of the desiccant's performance. The primary action needed is to replace the saturated desiccant to restore its ability to control humidity effectively. This step is crucial in maintaining the integrity of the environment where humidity control is vital.
