Drying Contaminated Structures

Principals of Drying

There are four general principles used in drying water damaged structures and materials. They may be used singularly, or more effectively, in combination. Drying is a necessity in order to restore water damaged materials to a pre-loss condition. The four principles of drying include: excess water removal, evaporation, dehumidification and temperature control.

The Use of Existing Drying Resources

Careful consideration must be given to whether using existing drying resources may negatively affect the indoor environment or pose a safety hazard. HVAC systems contaminated with biological growth and other materials must not be used as a drying resource. Exhaust systems or ceiling fans that pose an electrical hazard must not be used as drying resources.

Structural Materials

Throughout the restoration process, it is highly recommended that effort be directed toward anticipating secondary damage and attending to other structural components that may require drying, demolition, and/or replacement. These components may include, but are not necessarily limited to:

• Ceilings
• Walls
• Built-in furnishings and fixtures
• Insulation
• Structural wood
