質問 # 73
Which material loses most of its structural integrity when wet but regains its strength when dry?
正解：A
解説：
Gypsum board (drywall) is identified in the WRT body of knowledge as highly vulnerable to moisture exposure, yet capable of recovering strength when dried-provided it has not sustained irreversible primary damage. The WRT manual explains that gypsum wallboard is among the most moisture-sensitive common building materials, showing rapid and dramatic change with elevated moisture levels. However, it also states that gypsum has a greater ability to recover than many other engineered products.
Critically, the WRT guidance distinguishes between primary damage (immediate structural failure) and recoverable wetting. For example, overhead or horizontally installed gypsum that becomes wet can lose structural integrity, sag, and create a significant safety concern; this sagging is considered permanent damage and requires removal.
In contrast, when gypsum board installed vertically on walls is wet but has not experienced primary damage (e.g., not structurally compromised, not severely deteriorated, and appropriate contamination considerations are addressed), the WRT manual notes that it can restore: during the drying process, gypsum's original strength is restored, and after drying it may even be slightly stronger (though sometimes more brittle). This recovery characteristic is what makes gypsum board the best match to the question's description-losing structural integrity when wet yet regaining strength when properly dried.
This material behavior is central to WRT decision-making: whether to dry in place, perform limited disruption (e.g., baseboard removal and cavity airflow), or remove materials for safety/health reasons. The WRT body of knowledge treats gypsum as potentially restorable depending on installation orientation, degree of damage, and contamination risk, which is why it is specifically described as losing integrity when wet and regaining strength when dry.
質問 # 74
What is it called when moisture causes wood flooring to expand, resulting in the edges being higher than the center across the width of the board?
正解：A
解説：
Cuppingis the correct term used in the IICRC WRT body of knowledge to describe a condition where wood flooring expands due to moisture, causing the edges of each board to rise higher than the center. This deformation occurs because moisture is absorbed unevenly-typically from below-causing differential expansion across the board's thickness.
The WRT manual explains that cupping is most commonly associated with moisture intrusion affecting subflooring or elevated humidity conditions beneath the flooring. As the underside of the board absorbs moisture, it expands more than the top surface, resulting in a concave shape across the width.
This condition is distinct fromcrowning, which is the opposite deformation where the center is higher than the edges, often occurring after sanding cupped floors before moisture equilibrium is restored.Bucklingrefers to extreme deformation where boards lift completely from the subfloor, anddelaminationapplies to layered materials separating.
Understanding cupping is essential for restorers because it influences drying strategy, expectations, and post- drying recommendations. The WRT standard emphasizes careful moisture control and adequate acclimation time to allow wood flooring to return as close as possible to its original profile before repairs or refinishing are attempted.
質問 # 75
Which of the following is defined as removing water vapor from the air?
正解：B
解説：
The IICRC WRT body of knowledge definesdehumidificationas the process of removing water vapor from the air. This process is fundamental to restorative drying because evaporation alone does not remove moisture from a structure; it only changes liquid water into vapor. Without dehumidification (or ventilation), evaporated moisture would remain in the air and eventually re-condense on cooler surfaces.
The WRT curriculum explains that dehumidification works by reducing thehumidity ratio and vapor pressureof the air, thereby maintaining a vapor pressure differential that allows moisture to continue moving from wet materials into the surrounding environment. Refrigerant dehumidifiers accomplish this through condensation, while desiccant dehumidifiers remove moisture through adsorption.
Dehumidification must be properly balanced with airflow and temperature control. The WRT manual emphasizes that excessive evaporation without adequate dehumidification can increase ambient humidity, slow drying, and raise the risk of secondary damage. Conversely, effective dehumidification lowers relative humidity, reduces dew point, and supports sustained evaporation from wet materials.
Humidification is the opposite process, diffusion is passive vapor movement, and evaporation is only one step in the drying cycle. Only dehumidification actively removes water vapor from the air mass, making it the correct definition under WRT standards.
質問 # 76
If the ambient temperature is below 50°F, what is the most effective type of dehumidifier to use when drying a structure?
正解：C
解説：
The IICRC WRT body of knowledge states thatdesiccant dehumidifiersare the most effective option when ambient temperatures fall below approximately50°F. Refrigerant-based dehumidifiers rely on condensation at cold coils and become inefficient or inoperative at lower temperatures due to coil icing and reduced moisture removal capacity.
Desiccant systems remove moisture throughadsorption, a chemical bonding process that is not dependent on air temperature. This allows desiccants to perform effectively in cold environments where refrigerant units fail.
The WRT manual highlights desiccants as the preferred solution for cold structures, unheated buildings, winter losses, and Class 4 drying scenarios. Gas bypass and LGR units extend the operating range of refrigerants but still have temperature limitations.
Selecting the correct dehumidifier type based on ambient conditions is a core competency under the WRT standard and ensures efficient, defensible drying.
質問 # 77
When performing the initial inspection, which of the following could help determine the perimeter of wet carpet and cushion (pad, underlay)?
正解：B
解説：
The IICRC WRT body of knowledge recommends usinginfrared (IR) cameras and moisture sensorsto help determine the perimeter of wet carpet and cushion during the initial inspection. These tools allow restorers to quickly and non-destructively identify moisture patterns across large areas.
IR cameras can highlight temperature anomalies caused by evaporative cooling, while moisture sensors provide confirmation of moisture presence beneath carpet surfaces. The WRT manual stresses that IR imaging must always be verified with moisture detection instruments to avoid false positives.
Disengaging carpet or relying on touch is invasive, time-consuming, and unreliable. Borescopes and anemometers are not designed for carpet moisture detection.
Using appropriate detection tools supports accurate scoping, efficient drying design, and defensible documentation-core principles of professional restoration practice under the IICRC WRT standard.
