質問 # 56
What is recommended to minimize or control airborne contaminants during restoration?
正解：A
解説：
The IICRC WRT body of knowledge recommends the use ofAir Filtration Devices (AFDs)to minimize and control airborne contaminants during restoration activities. AFDs equipped with HEPA filtration capture airborne particulates, including dust, microbial fragments, and other contaminants generated during mitigation.
The WRT manual explains that uncontrolled airborne contaminants can pose health risks to workers and occupants and can spread contamination to unaffected areas. AFDs reduce this risk by continuously filtering air and, when properly configured, creating negative pressure within containment zones.
Dehumidifiers manage moisture, not particulates. Air movers can increase aerosolization if used improperly.
HVAC systems are not designed for contamination control during restoration and may spread contaminants throughout the structure.
AFDs are therefore the recommended engineering control for airborne contaminant management under the WRT standard of care.
質問 # 57
What should a restorer do when there is contamination (e.g., Category 2, Category 3, Mold) on a water damage restoration project to protect workers and occupants?
正解：B
解説：
The IICRC WRT body of knowledge emphasizes that when contamination is present, the restorer's responsibility is toprotect workers and occupantsby implementing appropriate controls. This includes the use ofpersonal protective equipment (PPE),containment systems, andengineering or administrative controlsas dictated by the hazard assessment.
Category 2 and Category 3 water, as well as mold-contaminated environments, can expose individuals to microorganisms, allergens, and other harmful agents. The WRT manual reinforces the hierarchy of controls:
eliminate hazards when possible, isolate hazards through containment, and protect workers with PPE when hazards cannot be fully removed.
Fogging disinfectants or wiping surfaces does not eliminate airborne or surface hazards and may actually increase aerosolization if done improperly. Contacting the insurance company is an administrative step and does not mitigate health risks.
The WRT curriculum also aligns with OSHA principles, stressing that safety controls must be implemented beforeandduringrestoration activities. Proper containment and PPE selection are essential to prevent cross- contamination and protect both restoration personnel and building occupants.
質問 # 58
What is the process used by refrigerant dehumidifiers to remove water from the air?
正解：B
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 # 59
In addition to low-humidity air, what can a restorer do to dry restorable subfloor under ceramic tile flooring?
正解：C
解説：
The IICRC WRT body of knowledge explains that drying restorable subflooring beneath ceramic tile is challenging because tile and grout assemblies havelow permeability, restricting vapor movement. In such conditions, evaporation must be enhanced by manipulating the remaining controllable variables-most notably temperature.
Increasing the temperature of the wet materials raises the vapor pressure within the subfloor, which increases the vapor pressure differential between the material and the surrounding air. This differential is the primary driving force that moves moisture out of materials and into the air. The WRT manual emphasizes that warmer materials evaporate moisture more readily, provided ambient air vapor pressure remains lower.
Lowering dehumidifier output temperature or increasing relative humidity would reduce drying efficiency.
Air filtration devices address airborne particulates and do not directly influence evaporation. Therefore, controlled heat application-within safe limits-is a recommended strategy when drying beneath low- permeance floor coverings.
The WRT curriculum reinforces that effective drying requires managinghumidity, airflow, and temperature together, particularly when materials restrict vapor transmission.
質問 # 60
How many gallons (liters) are present in a 20-foot by 25-foot basement with standing water at a depth of 4 feet 6 inches (1.37 meters)?
正解：B
解説：
The IICRC WRT body of knowledge stresses the importance of accurately estimating the volume of standing water to support proper extraction planning, equipment selection, and safety evaluation. This question requires a volumetric calculation using length, width, depth, and standard water conversion factors.
First, calculate the cubic volume of water:
20 ft × 25 ft × 4.5 ft =2,250 cubic feetof water.
According to WRT reference tables,1 cubic foot of water equals approximately 8.34 gallons. Multiplying:
2,250 cubic feet × 8.34 gallons/cu ft =18,765 gallons(rounded).
This calculation confirms option D as correct. The WRT curriculum includes these conversions to help restorers assess extraction time, pump capacity, disposal logistics, and safety hazards such as hydrostatic pressure or structural loading.
Understanding water volume is not merely academic. Large volumes of standing water significantly affect drying timelines, contamination potential, and classification decisions. The ANSI/IICRC S500 Standard emphasizes prompt and adequate bulk water removal as a critical first step in mitigation.
Accurate water-volume estimation also supports documentation and communication with materially interested parties, ensuring that restoration actions are technically justified and defensible.
