問題 #76
In order to effectively dry subflooring installed below sheet vinyl flooring, what should a restorer typically do?
答案：C
解題說明：
The IICRC WRT body of knowledge explains thatsheet vinyl flooring acts as a vapor barrier, significantly restricting moisture vapor movement from the subfloor beneath it. Because evaporation is inhibited, subflooring beneath vinyl cannot be effectively dried while the covering remains intact.
As a result, the WRT manual states that the most effective and reliable method is toremove and discard the vinyl flooringto allow direct access for drying. This enables airflow, temperature control, and dehumidification to act directly on the wet subfloor.
Perforating vinyl is unreliable and may cause additional damage without ensuring adequate vapor release.
Placing an air mover at an edge does not overcome the vapor barrier effect. Simply adding equipment without removing the barrier does not resolve the drying limitation.
Removing vinyl aligns with the WRT principle that vapor barriers must be addressed to achieve effective drying and prevent hidden moisture from causing secondary damage.
問題 #77
What is the term for the force exerted by water molecules in the air on surrounding surfaces?
答案：D
解題說明：
Vapor pressureis defined in the IICRC WRT body of knowledge as the force exerted by water vapor molecules in the air against surrounding surfaces. It represents the energy level of moisture in the air and is a key driver of moisture movement.
The WRT manual explains that water vapor moves from areas of higher vapor pressure to areas of lower vapor pressure, whether between materials and air or between different air masses. This principle governs evaporation, condensation, and moisture redistribution within a drying chamber.
Relative humidity describes a percentage relationship, humidity ratio measures moisture mass, and dew point identifies saturation temperature-but vapor pressure quantifies the actualdriving force. Because vapor pressure is directly influenced by both temperature and humidity ratio, it is considered one of the most precise indicators of drying potential.
Effective drying systems focus on lowering air vapor pressure relative to wet materials, ensuring continuous moisture migration out of structural components.
問題 #78
If outdoor conditions are favorable, what can be reduced with ventilation?
答案：A
解題說明：
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.
問題 #79
On a Class 4 water intrusion that is 2,000 square feet with an 8-foot ceiling height, how many 400 CFM desiccant dehumidifiers would you need initially?
答案：A
解題說明：
The IICRC WRT body of knowledge explains that Class 4 water intrusions involve deeply held or bound water and typically require specialized drying methods, including desiccant dehumidification. Initial desiccant sizing is based on cubic footage and airflow capacity rather than AHAM pints.
In this scenario, the affected volume is 2,000 square feet × 8 feet = 16,000 cubic feet. A common WRT starting guideline for desiccant systems is approximately one 400 CFM desiccant unit per 8,000 cubic feet for Class 4 conditions.
Dividing 16,000 cubic feet by 8,000 cubic feet per unit results in an initial recommendation of two 400 CFM desiccant dehumidifiers. This capacity provides sufficient airflow and moisture adsorption to manage the heavy moisture load typical of Class 4 losses.
The WRT manual stresses that this is an initial recommendation and must be validated through psychrometric monitoring and material moisture readings. Desiccant systems are often adjusted as drying progresses.
問題 #80
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?
答案：A
解題說明：
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.
