Quick Answer
High humidity causes paper documents to deteriorate, potentially leading to mold growth, yellowing, and brittle pages that become prone to tearing.
Effects of Humidity on Paper
High humidity can cause significant damage to paper documents, especially those containing important vaccination records. When the air is filled with moisture, it seeps into the paper fibers, causing them to swell and become more susceptible to damage. This can lead to a range of issues, including mold growth, yellowing, and brittleness.
Controlling Moisture Levels
To mitigate the effects of high humidity on paper documents, it’s essential to maintain a controlled environment. The ideal relative humidity (RH) for storing paper documents is between 30% and 50%. This can be achieved by using a dehumidifier or a humidistat, which can be set to maintain a specific RH level. It’s also crucial to avoid storing paper documents in areas prone to flooding or water damage.
Document Storage and Handling
Proper storage and handling of paper documents can also help prevent damage caused by high humidity. Documents should be stored in airtight containers or archival-quality folders, away from direct sunlight and moisture sources. When handling paper documents, it’s essential to wear gloves to prevent oils from your skin from transferring to the paper, which can cause further damage. Additionally, avoid touching or manipulating the paper unnecessarily, as this can cause creases and tears.
