質問 # 40
Which best describes Category 2 water?
正解：D
解説：
The IICRC WRT body of knowledge definesCategory 2 wateras water that contains significant contamination and has the potential to cause discomfort or illness if contacted or consumed. This classification recognizes that while Category 2 water is not grossly contaminated like Category 3, it is no longer considered clean or sanitary.
Examples commonly cited in the WRT manual include dishwasher or washing machine discharge, toilet overflows with urine but no feces, and seepage due to hydrostatic pressure. These sources may contain microorganisms, nutrients for microbial growth, or other contaminants that pose health concerns.
The WRT standard emphasizes that Category 2 water presents anelevated health riskand requires enhanced controls compared to Category 1. This may include increased PPE, more aggressive cleaning, and careful evaluation of materials for restorability. Porous materials affected by Category 2 water may need to be removed depending on exposure time and degree of absorption.
Importantly, the WRT body of knowledge highlights that water candegrade in categoryover time if left untreated. Category 2 water can become Category 3 due to microbial amplification, reinforcing the importance of timely mitigation and proper classification during the initial inspection.
質問 # 41
Which of the following materials is the most resistant to water damage?
正解：C
解説：
Among the listed materials,builder's grade plywoodis the most resistant to water damage according to the IICRC WRT body of knowledge. Plywood is composed of cross-laminated wood veneers bonded with water- resistant adhesives, giving it greater dimensional stability and moisture tolerance compared to other engineered wood products.
Tempered hardboard, medium-density fiberboard (MDF), and particleboard are all highly moisture-sensitive.
These materials rely on compressed fibers and resins that rapidly swell, lose structural integrity, and experience irreversible damage when exposed to water. The WRT manual identifies MDF and particleboard as particularly vulnerable, often requiring removal even after brief exposure.
Builder's grade plywood, while not immune to damage, can often tolerate wetting, dry effectively, and regain much of its structural performance if contamination conditions permit. This makes it more likely to be restorable under Category 1 or some Category 2 conditions, depending on exposure duration and degree of damage.
The WRT curriculum uses this comparison to help technicians make informed decisions during initial inspection and material evaluation, reinforcing that not all engineered wood products behave the same when wet.
質問 # 42
What is the term for the temperature at which air reaches 100% relative humidity?
正解：D
解説：
Dew point temperature is the temperature at which an air mass becomes saturated (100% RH) and can hold no more water vapor. In WRT psychrometry, this is a critical "threshold" condition because any additional cooling of the air (at the same moisture content) forces water vapor to change state and condense onto cooler surfaces. The WRT body of knowledge emphasizes that as air is cooled, its capacity to hold water vapor decreases until RH reaches 100%, which is the dew point condition.
In water damage restoration, dew point is used operationally to manage secondary damage risk and to confirm drying potential. The WRT reference explains that restorers compare the dew point of the indoor air (often the most humid air mass in the structure) to material surface temperatures throughout the affected environment. If a surface temperature is below the dew point, condensation will occur on that surface, potentially increasing moisture loading and causing secondary damage. Conversely, when surface temperatures are warmer than the dew point of the surrounding air, evaporation potential increases, supporting restorative drying.
Because dew point is directly related to humidity ratio and vapor pressure, it also functions as a practical indicator of "how wet the air really is" regardless of temperature changes. This is why dew point is repeatedly referenced alongside vapor pressure and humidity ratio as a foundational psychrometric measurement used to evaluate drying systems and to prevent condensation events during mitigation.
質問 # 43
Which material should be discarded when affected by Category 2 water?
正解：B
解説：
The IICRC WRT body of knowledge clearly states thatcarpet cushion (pad, underlay)must be discarded when affected byCategory 2 water. Cushion is a porous material that readily absorbs contaminants and cannot be effectively cleaned or disinfected once exposed to water containing significant contamination.
The WRT manual explains that while some materials may be dried or cleaned depending on conditions, carpet cushion presents a high risk of retaining microorganisms, nutrients, and odors. Retaining contaminated cushion increases the likelihood of secondary damage and occupant exposure.
Wood framing and plywood subfloors may be restorable depending on contamination duration and extent, and oriental rugs require specialized evaluation. Category 2 contamination alone is sufficient justification for cushion removal under WRT standards.
質問 # 44
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.
