WRT CERTIFICATION FINAL EXAM Questions with Accurate Answers Latest Updates 2024 GRADE A+ The most critical course of action in restorative drying is to _______ ______ and begin __________ as soon as possible. correct answers respond quickly & mitigation All restorers should follow the standard of care for the water restoration profession developed by the restoration industry entitled the IICRC ____. correct answers S500 To help protect technicians from the many hazards associated with contaminated water losses, restorers need to have ready access to several items.

During this process, the restorer inspects all ___________ ________ areas. correct answers potentially affected The ultimate goal is to find the "edge" of water migration, which moves in a three-dimensional path throughout the structure. This is accomplished across carpeted surfaces using a ________ ______, and across most hard surfaces using a ___-________ (non-penetrating) moisture meter. correct answers moisture sensor & non-invasive Water from a clean source with no substantial risk of causing sickness of discomfort is said to be ________ _ water. correct answers Category 1 Water that has a significant degree of chemical, biological, and/or physical contamination and a potential to cause sickness or discomfort is ________ _. correct answers Category 2 Cleaning procedures must be employed before the drying of a Category 2 water loss can continue. At a minimum, affected ______ ________ (or pad) must be removed and disposed of, and carpet must be throughly cleaned using hot water extraction method. correct answers carpet underlay When water intrusion results from a grossly unsanitary source or carries __________ (disease causing) agents, it is said to be Category 3. correct answers pathogenic Workers and occupant ______ and safety are the first priority on every sewage loss. Areas affected by Category 3 water intrusion are marked and posted as potentially hazardous. correct answers health Various cleaning and decontamination procedures must be used on Category 3 water losses, including the removal of all ______ ______ materials affected by the water intrusion. correct answers highly porous When resistance is encountered and performing proper services in a Category 3 water loss becomes a challenge, restorers ____ ____ immediately to prevent liability and address the conflict. correct answers stop work Third party experts are commonly referred to as Indoor Environmental Professionals, or ____. correct answers IEPs Losses where regulated or hazardous materials have contaminated the structure do not change the _______ of water. correct answers category Pre-existing conditions should be identified, documented, and communicated to all __________ __________ parties during the initial inspection. correct answers materially interested When carpet delamination (the loss of integrity in the adhesives used to laminate the _______ and _________ backings) has occurred, further damage is very likely. For this reason, when extensive carpet delamintation is discovered, technicians must call it to the attention of all materially interested parties, document the condition and suggest ___________. correct answers primary, secondary, & replacement There are a number of causes for carpet delamination -- many of them related to ________ restoration activities. correct answers improper Typical causes of carpet delamination are: correct answers 1. Folding or stretching carpet when wet 2. Overly aggressive extraction 3. Improperly specified carpet underlay 4. Improper installation ___________ occurs when a solid changes to a vapor (without going through a liquid phase.) correct answers Sublimation Freeze drying (sublimation) is typically used with valuable saturated books and documents. Books and documents saturated with clean water may be restorable if: ______ or _____ as quickly as possible. correct answers Frozen & dried ________ ________ is defined as the amount of moisture contained in an air sample, as compared to the maximum amount the air could hold at that temperature. correct answers Relative humidity (RH) When the air temperature increases, it can hold ____ water vapor. correct answers more In the restorative drying industry the weight measurement used to measure water vapor in air is grains per pound of air, abbreviated as GPP. This is called ________ _____. correct answers humidity ration Which of these surface temperatures would promote the most rapid evaporation? A. 60 degrees B. 70 degrees C. 80 degrees correct answers C. 80 degrees If a material is not drying well, what would be the most effective method of increasing evaporation? A. Use air filtration B. Warm the material C. Add more airflow correct answers B. Warm the material One of the most effective methods of drying wet wood under hard surfaces is: A. Heated airflow B. Demolition of the wood C. Negative air pressure correct answers A. Heated airflow ___ _____ is the temperature at which air becomes saturated with moisture and can hold no more water vapor. correct answers Dew point When air is cooled, its capacity for water vapor is reduced. Eventually, if temperature is cooled enough, the relative humidity will reach ___% or saturation. When this occurs, the air has reached its ___ point temperature. correct answers 100% & dew If surfaces are ______ that the dew point of the surrounding air, water will condense on those surfaces and possibly cause secondary damage. If surfaces are ______ that the dew point of the surrounding air, evaporation can occur. correct answers cooler & warmer _____ ________ is the force exerted by a gas (vapor molecules) on the surrounding environment. correct answers Vapor pressure Vapor pressure, dew point, and humidity ration (GPP) are ________ _______ to each other. When one increases, the other two ________. When one decreases, the other two ________. correct answers directly related, increase, & decrease Water vapor pressure is the force that drives higher concentrations of humidity from one space to another in an attempt to seek ___________ with lower concentrations of water vapor. correct answers equilibrium The ability for water vapor to diffuse through a solid material is expressed as the materials _________. correct answers permeance 3 drying systems: correct answers 1.
