When drying damp documents, why is direct heat to be avoided and what should be used instead?

• A. Direct heat is ideal for drying damp documents quickly.
• B. Direct heat is safe and recommended for all documents.
• C. Direct heat should be applied to damp documents to prevent tearing.
• D. Avoid direct heat; use air movers and dehumidifiers to dry damp documents.

Answer: (D)

Direct heat pulls moisture out of damp documents too quickly and unevenly, causing stresses in the paper fibers that lead to warping, curling, or tearing. It can also cause inks to smear or pigments to shift, and it may damage adhesives or coatings. A safer, more controlled approach uses air movers to circulate air across the surfaces and dehumidifiers to remove moisture from the surrounding air. This combination dries the documents gradually and evenly, reducing the risk of damage and preserving readability and structure. That’s why avoiding direct heat in favor of air movement and humidity control is the recommended method.
