What should be done to maintain temperature and humidity in storage?

• A. They should be controlled to protect stored materials.
• B. They should be set to the maximum.
• C. They should be ignored.
• D. They should be changed hourly.

Answer: (A)

The main concept here is actively controlling environmental conditions in storage to protect products. By keeping temperature and humidity within defined, appropriate ranges, you prevent spoilage, microbial growth, condensation, and quality degradation. Stability matters—fluctuations can cause moisture migration, mold, and texture or quality loss.

So, the correct approach is to manage and adjust storage conditions based on monitoring data, using calibrated thermometers and humidity sensors, alarms, and standard operating procedures. This ensures consistent conditions that keep stored materials safe and appealing.

Choosing maximum settings would risk damage or drying out, ignoring conditions allows deterioration over time, and changing them hourly creates instability—none of these protect the stored goods.
