質問 # 43
When is a closed drying system recommended during restoration?
正解：B
解説：
The IICRC WRT body of knowledge defines aclosed drying systemas one in which indoor air is isolated from outdoor air, relying on mechanical dehumidification rather than ventilation. A closed system is recommendedwhen the outdoor humidity ratio is higher than the indoor humidity ratio.
Introducing outside air with a higher humidity ratio would add moisture to the drying environment, reducing evaporation potential and increasing the risk of secondary damage. The WRT manual emphasizes that ventilation decisions must be based on psychrometric comparison-not convenience or assumptions about temperature.
Closed systems allow restorers to control indoor conditions precisely using dehumidifiers, air movers, and temperature management. This approach is particularly important during humid weather, rain events, or in climates where outdoor air consistently contains more moisture than indoor air.
Building security, equipment monitoring frequency, or the availability of dry outdoor air do not determine whether a closed system is appropriate. The determining factor is always moisture content of the air.
This guidance reinforces the WRT principle that effective drying depends oncontrolling vapor pressure differentials, which can only be achieved by preventing moisture-laden air from entering the drying chamber.
質問 # 44
Who should a technician get documented authorization from before applying an antimicrobial (biocide)?
正解：A
解説：
The IICRC WRT body of knowledge clearly states that before applying an antimicrobial (biocide), a technician must obtaindocumented authorization from the owner or occupant, or another legally authorized representative of the property. This requirement exists because antimicrobial application involves introducing regulated chemical agents into an occupied environment, which carries potential health, legal, and liability implications.
The WRT manual emphasizes informed consent as a professional and ethical obligation. Owners or occupants must be made aware of the purpose, limitations, and potential risks associated with antimicrobial use.
Documented authorization protects all materially interested parties by confirming that the decision to apply a biocide was disclosed, understood, and approved.
Insurance adjusters do not have authority over health decisions within a structure, reconstruction contractors do not represent occupancy interests, and physicians are not responsible for property treatment approvals. The responsibility lies with the property owner or occupant.
This requirement aligns with EPA pesticide regulations and the ANSI/IICRC S500 Standard, reinforcing transparency, safety, and defensibility in restoration practices.
質問 # 45
As the air temperature increases and no additional moisture is added to the air, what happens to relative humidity?
正解：C
解説：
The IICRC WRT body of knowledge explains thatrelative humidity decreaseswhen air temperature increases and no additional moisture is added. This occurs because warmer air can hold more water vapor; therefore, the same amount of moisture represents a smaller percentage of the air's total capacity.
This principle is foundational in psychrometry and directly applied in restoration drying. By increasing temperature while controlling moisture content, restorers lower relative humidity and vapor pressure, increasing evaporation potential.
Relative humidity does not remain constant with temperature changes, nor does it increase unless moisture is added. Dew point remains unchanged unless moisture content changes.
Understanding this relationship allows restorers to use controlled heat strategically to improve drying efficiency without introducing excess moisture.
質問 # 46
Which product provides the least amount of reduction in microorganisms?
正解：D
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 # 47
When using LGR dehumidifiers in a Class 3 water intrusion containing 9,000 cubic feet, what is the recommended dehumidification capacity?
正解：B
解説：
The IICRC WRT body of knowledge provides guidance for initial LGR dehumidification capacity based on cubic footage and class of water. For Class 3 intrusions, which involve the greatest amount of moisture absorption and evaporation (excluding Class 4), a higher dehumidification capacity is required.
A commonly taught WRT guideline is approximately one LGR dehumidifier (#150 PPD) per 3,000 cubic feet for Class 3 conditions. Applying this to a 9,000 cubic foot drying chamber results in a total recommended capacity of approximately 450 PPD.
This capacity ensures that evaporated moisture is removed efficiently, preventing elevated humidity and secondary damage. The WRT curriculum emphasizes that insufficient dehumidification in Class 3 losses can stall drying and increase microbial risk.
As with all equipment recommendations, this is an initial placement subject to adjustment based on monitoring data, but 450 PPD represents the correct starting capacity under WRT guidance.
