질문 # 77
How shall a technician use government-registered antimicrobials (biocides)?
정답：A
설명：
The IICRC WRT body of knowledge mandates that EPA-registered antimicrobials (biocides) must be used strictly in accordance with the product label directions. Under U.S. law, the label is considered a legal document, and deviation from label instructions constitutes misuse of a pesticide.
Label directions specify approved application methods, dilution ratios, dwell times, PPE requirements, ventilation needs, and occupant restrictions. The WRT manual emphasizes that technicians are not permitted to alter concentrations, combine products, or improvise application techniques, regardless of perceived effectiveness.
Estimating dilution or increasing concentration does not improve efficacy and may create safety hazards, damage materials, or expose occupants and workers to chemical risks. Combining products can produce toxic reactions, while under-dilution or over-dilution may render the antimicrobial ineffective or unsafe.
The WRT curriculum reinforces that antimicrobials are supplemental tools, not replacements for removal of unsalvageable materials or proper drying. Proper use ensures regulatory compliance, protects health, and limits liability for the restorer.
질문 # 78
What does a restorer need to know to determine the initial dehumidification capacity recommendation?
정답：D
설명：
According to the IICRC WRT body of knowledge, theinitial dehumidification capacity recommendationis determined by three primary factors:cubic footage of the affected area,class of water intrusion, andtype of dehumidifierbeing used. This calculation establishes a baseline moisture removal capability required to manage the anticipated evaporation load.
Cubic footage defines the volume of air within the drying chamber and directly influences how much moisture must be removed from the environment. Theclass of waterdescribes how much moisture has been absorbed by materials and the rate of evaporation expected. Higher classes (Class 3 and 4) require substantially more dehumidification capacity due to increased moisture loading and deeply absorbed water.
Thetype of dehumidifieris equally critical because different technologies (conventional refrigerant, LGR, desiccant) have vastly different operating ranges, efficiencies, and moisture removal characteristics. The WRT manual specifically differentiates capacity calculations for LGR versus desiccant systems, as they function under different psychrometric conditions.
Factors such as category of water, subfloor type, or air mover quantity influenceprocedural decisions, safety, and drying strategy-but they are not part of the initial capacity calculation. Likewise, grain depression is a performance outcome used for evaluation, not an input variable.
This structured approach ensures consistency, defensibility, and alignment with the ANSI/IICRC S500 Standard, enabling restorers to justify equipment placement using measurable, science-based criteria rather than guesswork or habit.
질문 # 79
Which of the following materials is the most resistant to water damage?
정답：D
설명：
Among the listed materials,builder's grade plywoodis the most resistant to water damage according to the IICRC WRT body of knowledge. Plywood is composed of cross-laminated wood veneers bonded with water- resistant adhesives, giving it greater dimensional stability and moisture tolerance compared to other engineered wood products.
Tempered hardboard, medium-density fiberboard (MDF), and particleboard are all highly moisture-sensitive.
These materials rely on compressed fibers and resins that rapidly swell, lose structural integrity, and experience irreversible damage when exposed to water. The WRT manual identifies MDF and particleboard as particularly vulnerable, often requiring removal even after brief exposure.
Builder's grade plywood, while not immune to damage, can often tolerate wetting, dry effectively, and regain much of its structural performance if contamination conditions permit. This makes it more likely to be restorable under Category 1 or some Category 2 conditions, depending on exposure duration and degree of damage.
The WRT curriculum uses this comparison to help technicians make informed decisions during initial inspection and material evaluation, reinforcing that not all engineered wood products behave the same when wet.
질문 # 80
What should a restorer do to reduce the aerosolization of contaminants?
정답：C
설명：
The IICRC WRT body of knowledge explains thataerosolization of contaminantsoccurs when airflow disperses particulate matter, microorganisms, or contaminated droplets into the air. To reduce this risk, restorers shouldminimize air movementin contaminated areas until proper controls are in place.
In Category 2, Category 3, or mold-affected environments, uncontrolled airflow can spread contaminants beyond the affected area, increasing exposure risk and cross-contamination. The WRT manual emphasizes that airflow should be strategically managed and often delayed until containment and air filtration devices (AFDs) are installed.
Increasing air movement or temperature without controls can worsen aerosolization. Temperature reduction alone does not address particulate dispersion. Minimizing air movement-combined with containment and filtration-is the recommended approach under WRT safety principles.
질문 # 81
Typically, what can cause delamination when carpet is wet?
정답：D
설명：
The IICRC WRT body of knowledge identifiesimproper handling and disengagingas a primary cause of carpet delamination during water damage restoration. Delamination occurs when the carpet's primary and secondary backing layers separate, often due to mechanical stress while the carpet is wet and structurally weakened.
When carpet becomes wet, the latex adhesives bonding the backing layers soften and lose strength. If technicians pull, drag, or disengage carpet incorrectly-especially without proper tools such as knee kickers or power stretchers-the weakened backing can separate. The WRT manual emphasizes that wet carpet must be handled carefully and evenly to avoid introducing avoidable secondary damage.
Ambient conditions above dew point, antimicrobial application, or tuft bind strength alone do not typically cause delamination. While shrinkage and tuft bind issues may occur during improper drying, delamination is most often associated withphysical mishandlingduring lifting or removal.
The WRT curriculum stresses that secondary damage caused by improper techniques is the responsibility of the restorer. Proper disengaging methods, correct tools, and controlled handling are essential to preserve restorable carpet systems and reduce liability.
