質問 # 45
Which material loses most of its structural integrity when wet but regains its strength when dry?
正解：C
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 # 46
What is the most likely result when the rate of evaporation is greater than the rate of dehumidification?
正解：D
解説：
When evaporation outpaces dehumidification, the IICRC WRT body of knowledge explains that moisture accumulates in the air, increasing humidity ratio, vapor pressure, and relative humidity. This condition can stall drying and significantly increase the risk ofsecondary damage.
Excess moisture in the air can migrate into unaffected hygroscopic materials, cause condensation on cooler surfaces, and promote microbial growth. The WRT manual stresses that evaporation and dehumidification must be balanced so that moisture removed from materials is promptly removed from the air.
Rather than reducing humidity or vapor pressure, insufficient dehumidification leads to moisture saturation of the air, undermining the drying process. Monitoring psychrometric conditions allows restorers to correct imbalances before secondary damage occurs.
質問 # 47
Which product provides the least amount of reduction in microorganisms?
正解：C
解説：
The IICRC WRT body of knowledge distinguishes antimicrobial products based on their intended level of microbial reduction. Asanitizerprovides theleast reduction in microorganisms, lowering microbial populations to levels considered acceptable by public health standards but not eliminating most organisms.
Disinfectants provide a higher level of reduction by killing or inactivating many microorganisms, fungicides specifically target fungi, and sterilizers destroy all forms of microbial life, including spores. Sanitizers are therefore the lowest tier in terms of antimicrobial effectiveness.
The WRT manual emphasizes that sanitizers are not appropriate for significant contamination scenarios such as Category 2 or Category 3 water losses. Using insufficient antimicrobial controls can result in persistent contamination and liability exposure.
Understanding these distinctions ensures restorers select appropriate products based on contamination level and regulatory guidance, reinforcing professional and compliant practice.
質問 # 48
What is the process used by refrigerant dehumidifiers to remove water from the air?
正解：A
解説：
Refrigerant dehumidifiers remove moisture from the air through the process ofcondensation, as outlined in the IICRC WRT body of knowledge. In this process, warm, moist air is drawn across a cold evaporator coil inside the dehumidifier. When the air temperature is reduced below its dew point, water vapor changes phase from a gas to a liquid and condenses on the coil surface.
The collected liquid water then drains into a reservoir or is pumped out of the unit, while the dried air is reheated slightly and discharged back into the drying chamber. This mechanism is fundamental to both conventional refrigerant and low-grain refrigerant (LGR) dehumidifiers.
The WRT curriculum contrasts condensation withadsorption, which is used by desiccant dehumidifiers, and absorption, which involves liquids-not air drying. Sublimation (solid to vapor) is not relevant to restoration drying.
Understanding condensation is essential because refrigerant dehumidifiers rely on sufficient temperature and humidity conditions to function efficiently. The WRT manual highlights operational limits and emphasizes monitoring to ensure that refrigerant systems are appropriate for the environmental conditions present on the job.
質問 # 49
If outdoor conditions are favorable, what can be reduced with ventilation?
正解：B
解説：
The IICRC WRT body of knowledge explains that when outdoor air has alower humidity ratiothan indoor air, ventilation can be used to reduce the indoor humidity ratio by replacing moist air with drier outside air.
This reduction directly supports evaporation and drying.
Ventilation works by exchanging air masses. If the incoming air contains less moisture per pound of dry air, the overall moisture content of the drying chamber decreases. The WRT manual stresses that psychrometric comparison-not temperature or relative humidity alone-must be used to determine whether outdoor air is suitable.
Ventilation does not directly reduce microbial growth; rather, it reduces moisture conditions that support microbial amplification. Static electricity and sublimation are unrelated to ventilation drying.
Properly applied ventilation is recognized by the WRT standard as a legitimate moisture removal method when conditions allow, though it must be monitored to ensure effectiveness and prevent unintended moisture introduction.
