質問 # 74
In a room that measures 15 feet × 25 feet with the entire floor wet, minimal wicking up the walls (less than 2 feet), and no offsets; initially, how many air movers should be added?
正解：D
解説：
The IICRC WRT guidance uses an initial air-mover recommendation based on affected surface area to support evaporation across wet materials. The WRT manual summarizes the S500-based starting method: (1) place one air mover for each affected area, then (2) add one air mover for every 50 to 70 square feet of affected floor area, and then consider additional adjustments for offsets/insets and other complexities as applicable.
Here, the room is a single affected area and the entire floor is wet. The floor area is 15 × 25 = 375 square feet.
Using the WRT/S500 initial guidance, the floor-area addition is:
* High end: 375 ÷ 50 = 7.5 # round up to 8 air movers
* Low end: 375 ÷ 70 = 5.36 # round up to 6 air movers
Then include the "one per affected area" base air mover for the room. That yields an initial range of 7 to 9 total air movers (1 + 6 to 1 + 8). This matches the correct selection range.
The scenario also states wall wicking is minimal (less than 2 feet) and there are no offsets, so the wall-above-
2-feet rule and offset additions do not apply in the initial count. The objective at this stage is continuous airflow across wet surfaces to maintain a low-humidity boundary layer at the material surface, supporting rapid evaporation. The WRT manual further notes that airflow needs vary by the amount of wet surface area, accessibility, and other field limitations, and professional judgment may require adjustment after monitoring confirms actual drying progress.
質問 # 75
What steps should be taken to minimize safety concerns with sagging gypsum board ceilings and promote rapid drying?
正解：C
解説：
The IICRC WRT body of knowledge identifiessagging gypsum board ceilingsas a seriousstructural and safety hazard. Gypsum board loses strength when wet, especially in horizontal installations, and sagging indicates primary damage that cannot be safely reversed.
The WRT manual clearly states that wet gypsum ceilings presenting sagging or collapse risk must bedrained, safely removed, and properly disposed of. Attempting to dry sagging ceiling drywall in place is unsafe and inconsistent with professional standards.
Perforation or temporary support does not restore structural integrity and exposes workers and occupants to collapse hazards. Reinstallation is only appropriate after damaged materials are removed and the structure is dried.
This guidance reinforces the WRT principle thatlife safety always overrides salvage considerations.
Removing compromised ceiling drywall eliminates hazards and allows drying equipment to operate more effectively on remaining structural components.
質問 # 76
What term best describes the amount or weight of water vapor within a given weight of dry air?
正解：B
解説：
The IICRC WRT body of knowledge defineshumidity ratioas theamount (or weight) of water vapor contained in a given weight of dry air. It is typically expressed as grains per pound (GPP) or grams per kilogram and represents an absolute measurement of moisture in the air.
Unlike relative humidity, humidity ratio does not change with temperature unless moisture is added or removed. This makes it one of the most reliable psychrometric measurements for evaluating drying potential and comparing indoor and outdoor air conditions.
The WRT manual emphasizes that humidity ratio is critical for determining vapor pressure, dew point, and the suitability of ventilation drying. Restorers frequently rely on humidity ratio to decide whether introducing outdoor air will improve or hinder drying.
Moisture content applies to materials, not air, and relative humidity is a percentage comparison rather than a mass measurement. Therefore, humidity ratio is the correct and precise term under WRT psychrometric science.
質問 # 77
If outdoor conditions are favorable, what can be reduced with ventilation?
正解：C
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.
質問 # 78
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.
