IICRC - Applied Structural Drying
1. Air Filtration Device (ADF)
ANS Commonly called an air scrubber or negative air machine if airborne particles need to be
reduced, you could use an appropriatelyinstalled
2. Air Filtration Device
ANS AFD
3. Assembly Construction
ANS Prior to determining the best drying system for affectedmaterials, restorers should identify
and understand the assembly construction (ie wall assembly, floor assembly)
4. Category 1
ANS water originates from a sanitary source and does not pose substan-tial risk for dermal,
ingestion, inhalation, or exposure. Uncontaminated and routinelycleaned
5. Category 2
ANS water contains significant contamination and has the potential tocause discomfort or
sickness if contacted or consumed by humans
6. Category 3

ANS water is grossly contaminated and can contain pathogenic, toxigenic,or other harmful agents
7. Sewage Back Up
ANS Category 3
8. Clean water supply line
ANS Category 1
9. Class 1
ANS Least amount of water absorption and evaporation load - Wet porousmaterials - water
loss is less then 5% of the area
10. Class 2
ANS Significant amount of water absorption and evaporation load - waterintrusion where
wet represents 5% - 40% of the area.
11. Class 3
ANS greatest amount of water absorption and evaporation load. Waterintrusion where wet
represents over 40% of the area
12. Class 4
ANS deeply held or bound water. Significant amount of water absorption intolow evaporation
materials.Drying may require special drying methods, longer dryingtime, or substantial water
vapor pressure differentials.

13. Closed drying system
ANS Uses mechanical dehumidification and is not open tooutside air. Used if there are security
issues, the outside air is not conductive to drying or when access to outside air is not possible.
14. Conventual refrigerant dehumidifier
ANS Removes water vapor from the air by lowering the temperature of the incoming air to
below dew point and causing the water to condense on the coils. Cold and hot surfaces created
with gases inside aclosed coil system.
15. Combination Drying System
ANS uses some outdoor air with dehumidifiers to accelerate the drying process.This can
include periodically venting (flushing) thestructure, using negative pressure or using small
openings to the outside
16. Desiccant dehumidifier
ANS Removes water vapor from the air through absorption.Usually requires more amperage as
compared to refrigerant dehumidifier. Desic- cants create the lowest vapor pressure which
work best on low porosity materials. When a desiccant dehu is drawing outside air and ducting
processed air inside a
