IICRC WRT Exam Review
1. Hygroscopic materials gain and lose moisture continually in an effort to
with the water content in the surrounding air mass.Themore
hygroscopic the material, the faster it will collect water vapor, and the easier it will suffer
damage.: Equalize
Secondary
2. When water intrusion results in water running through wall cavities, in- spection access
holes are used to ensure that blown-in insulation has notcompacted and lost its .: R - Value
3. The most effective way to speed the drying process is to remove as muchof the water in a
liquid state as possible during the phase (for example, multiple extractions). Poor
extraction will significantly slow the drying process.: Extraction
4. Abide by local and regulations when disposing
extracted water. Waste water is best disposed of into a sanitary sewer.: Laws
5. The primary goal of the initial extraction of the affected area is to containfurther of
the water within the structure.: Migration
6. Whenever carpet must be disengaged from the tackless strip, a
and carpet awl must be used.: Knee Kicker
7. The majority of cushion has a skin or mesh on the top side. The purpose of this skin is to
ease during
instal-lation; it is not a vapor barrier.: Carpet Stretching
8. If the carpet is to be re-installed, technicians should avoid cutting carpet seams unless it is
absolutely .: Necessary
9. How many gallons of water are present in a basement that measures 30' × 25' where water
is standing at a depth of 6' 9"? (L x W = Sq Ft x Inches Deep / 12 = Cu Ft) (Cu Ft x 7.48 =
Gallons): 30 x 25 = 750 Sq Ft
(6 x 12) + 9 = 81 Inches Deep
750 x 81 = 60, = 5,062.5 Cu Ft
5,062.5 x 7.48 = 37,867.5 Gallons
10. Every cubic foot of standing water present in a structure contains
gallons (28.3 liters), and each gallon (3.8 liters) of water weighs 8.34 pounds
(3.8 kg).: 7.48
11. There are three levels of biocidal activity, according to the Environmental Protection
Agency (EPA) [Provide name and description, starting with weak-est]:
, :
Sanitizer:
Designed to reduce the # of pathogenic microorganisms to a safe level. This is thelowest level
of biocidal activity.
Disinfectant: Designed to destroy or inactivate microorganisms, not spores. Sterilizers:
Designed to destroy/eliminate all forms of microorganisms and all spores
12. Whenever a chemical antimicrobial or biocide is used, restorers mustfollow the label
explicitly.: Directions
13. Most antimicrobials require that the area of application be vacated by
and pets during application and for a period of time after appli-cation.:
Occupants
14. Establishing a is the best way to set restorative
drying goals. A dry standard is established by obtaining a moisture readingusing an
material.: Dry Standard
Unaffected
15. The numerical value from a moisture meter can be documented and usedto monitor
progress. For this reason, the amount of moisture absorbed by semi-porous structural materials
is measured most accurately with a moisture
, not a moisture sensor.: Meter
16. Because of their non-invasive nature and quick surveying capabili- ties, noninvasive
meters are the most effective tools for locating abnor-
mal moisture behind and beneath finishing materials such as
and resilient floor coverings.: Ceramic Tile
Vinyl
17. A thermo-hygrometer is used to monitor any air that can
influence the and/or
within a restorative drying environment.: Temper-ature
Relative Humidity
18. To evaluate the progress of structural drying projects, restorers shouldmeasure:
moisture in being dried (moisture content readings)
