質問 # 22
How shall a restorer dispose of wastewater?
正解：A
解説：
The IICRC WRT body of knowledge states that wastewater generated during water damage restoration must be disposed ofin accordance with applicable local, state, and federal laws and regulations. Wastewater may contain contaminants, sediments, microorganisms, or chemical residues, and improper disposal can create environmental and public health risks.
The WRT manual emphasizes that restorers are responsible for understanding disposal requirements within the jurisdiction where work is performed. These requirements may regulate where wastewater can be discharged (e.g., sanitary sewer systems) and prohibit disposal into storm drains, onto soil, or into surface waters. Disposal practices may also vary depending on contamination category, such as sewage or chemically contaminated water.
OSHA regulations focus on worker safety, not wastewater disposal. AHAM standards apply to appliance performance testing, not environmental disposal. ANSI/IICRC S520 addresses mold remediation, not wastewater handling. Therefore, none of those documents define wastewater disposal requirements.
By following applicable laws and regulations, restorers ensure environmental compliance, protect public infrastructure, and reduce legal liability. This requirement reflects the WRT emphasis on regulatory awareness and responsible professional conduct.
質問 # 23
How often should a restorer record and monitor measurements during the drying process?
正解：D
解説：
The IICRC WRT body of knowledge requires that restorersrecord and monitor drying measurements at least daily. Daily monitoring ensures that drying systems are functioning properly, drying goals are being approached, and adjustments can be made promptly if progress stalls.
Measurements typically include air temperature, relative humidity, humidity ratio, dew point, and moisture content or moisture levels of affected materials. The WRT manual emphasizes trend analysis-comparing daily readings to confirm consistent moisture reduction.
Infrequent monitoring increases the risk of unnoticed equipment failure, elevated humidity, condensation, or secondary damage. Weekly or bi-weekly monitoring does not meet the professional standard of care outlined in the ANSI/IICRC S500 Standard.
Daily documentation also supports defensibility by demonstrating continuous oversight and proactive management of the drying process. It provides transparency to materially interested parties and ensures accountability throughout the project lifecycle.
質問 # 24
What do moisture detection instruments allow a restorer to evaluate and document?
正解：A
解説：
The IICRC WRT body of knowledge states that moisture detection instruments allow restorers to evaluate and documentpsychrometric conditions and moisture content or moisture level readings. These measurements form the foundation of drying verification and defensible documentation.
Moisture meters measure moisture within materials, while thermo-hygrometers capture air temperature and relative humidity, enabling calculation of dew point, humidity ratio, and vapor pressure. Together, these tools allow restorers to assess drying effectiveness, establish drying goals, and demonstrate progress over time.
Thermal imaging provides indirect information and must be verified, while manometers and particulate counters serve specialized purposes outside routine moisture documentation.
The WRT manual emphasizes consistent measurement, proper instrument selection, and clear documentation as essential components of professional restoration practice and project closeout.
質問 # 25
What is the process used by refrigerant dehumidifiers to remove water from the air?
正解：D
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 # 26
Which material should be discarded when affected by Category 2 water?
正解：C
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.
