IICRC WRT Test 2023/2024 100+ QUESTIONS AND CORRECT ANSWERS GRADED A #1. During the inspection proces s, restorers shall make a reasonable effort to - CORRECT ANSWER --C. identify and address potential safety hazards #2. A significant amount of water absorption and evaporation load where wet porous materials represent ~5% to ~40% of combined ceiling, walls , and flooring surface areas and where low evaporation materials and assemblies are minimally wet is - CORRECT ANSWER --B. class 2 #3. Multiple extraction of salvageable materials, especially porous material (e.g. Carpet , cushion) often are required to: - CORRECT ANSWER --decrease drying time #4. To enhance drying, restorers should manage both ambient temperature and - CORRECT ANSWER --surface temperatures of affected materials #5. Water damage restoration services should not begin until after the: - CORRE CT ANSWER --restorer has entered into an adequately written contract. #6. Two tools that should be used to properly disengage most stretched -in carpet - CORRECT ANSWER --Knee kicker and carpet awl #7. When inspecting a water damage structure, restorers sho uld inspect: - CORRECT ANSWER --all potentially affected areas . #8. Buckled or damaged particle board should - CORRECT ANSWER --removed and replaced with new material. #9. upon entering a building, professional moisture detection equipment should be used to evaluate and document: - CORRECT ANSWER --applicable psychrometric conditions and moisture content or level readings . #10. When wet, a structural material that loses most of its structural integrity, but regains its strength when dry, is: - CORRECT ANSWER --Concrete #11 Initially, a method of search for abnormal moisture behind ceramic tile or resilient flooring can be accomplished by - CORRECT ANSWER --using a non -penetrating (non -
invasive) moisture meter #12. To minimize damage and reduce drying time, reduce drying time, restorers should: - CORRECT ANSWER --begin mitigation as soon as safely possible #13. The moisture content of structural materials should be measure d with a - CORRECT ANSWER --A. moisture meter #14. When accessible from below, to dry wet wood subflooring under stone or tile flooring, restorers can use low -humidity air and - CORRECT ANSWER --D. vapor barrier #15. Biocides designed to destroy or elimina te all forms of microbial life and their spores are - CORRECT ANSWER --D. sterilizers #16. When carpet is wet it can be delaminated by - CORRECT ANSWER --D. improper handling and disengaging #17. To minimize or control aerosolized soils or contaminants dur ing restoration, restorers can: - CORRECT ANSWER --B. install one or more air filtration devices (AFDs) #18. When pre -existing damage is discovered, restorer should - CORRECT ANSWER --
D. document and bring it to the attention of materially interested partie s #19. Rapid drying of structural materials is achieved by - CORRECT ANSWER --A. promoting evaporation and dehumidification or ventilation #20. When carpet and cushion (pad, underlay) are saturated with Category 3 water - CORRECT ANSWER --B. Both should be removed for proper disposal #21. To minimize safety concerns and to speed structural drying, gypsum board (drywall) ceilings that are saturated and sagging should be - CORRECT ANSWER --A. drained, removed quickly, and properly disposed #22. The force exe rted by water molecules in the air on surrounding surfaces is - CORRECT ANSWER --b. Vapor Pressure (page 11) #23. Generally, fastest rate of evaporation from wet materials with a 70F (21C) surface temperature [0.67 VP] would be an environment with - CORRECT ANSWER --A. 60F (4C) and 80% RH #24. Two hazardous materials more likely found in older building that requi re compliance with laws and regulations when handled are - CORRECT ANSWER --C. lead-based paint and asbestos #25. As humidity ratio increases (or decreases) another psychrometric chart property that also increases (or decreases) is - CORRECT ANSWER --C. vap or pressure #26. Ventilating a structure during the initial stages of restoration can be effective way to enhance drying by reducing the build up of - CORRECT ANSWER --C. humidity
