1. In order to effectively dry wood subfloor beneath vinyl floor, restorersshould remove the
: vinyl floor
2. When cellulosic insulation gets wet it should be :
removed
3. Gypsum board that is saturated and sagging should safely and .: Drained and
removed
4. When inspecting a water damaged structure, techs should inspect all
areas: potentially affected
5. Class water losses contain the least amount of water absorption andevaporation
load where wet, porous materials represent less than 5% of the combined floor, wall and
ceiling surface area in the space: 1
6. Class water losses contain a significant amount of water absorptionand
evaporation load where wet, porous materials represent 5%-40% of the combined, floor, wall
and ceiling surface area in the space: 2
7. The greatest amount of water absorption and evaporation load where wet,porous materials
represent more than 40% of the combined wall, floor, and ceiling surface areas and where low
evaporation materials or assemblies haveabsorbed minimal moisture is a Class :3
8. Water intrusion that involves a significant amount of water absorption bound within low
evaporation materials and may require longer drying timesis a class : 4
9. moisture detection equipment should be used to measure and docu- ment
and .: Mois-ture content and relative humidity readings.
10. A can be used to determine the extent of water migrationin carpet
and pad: moisture sensor
11. Thermo-hygrometer: measures temperature and humidity
12. Moisture levels of structural materials are measured and dry standards aredetermined using
a : moisture meter
13. To locate moisture beneath ceramic tile restorers should use a
moisture meter: non-invasive or non penetrating
14. do not detect moisture but can be a useful tool in iden-tifying
potentially wet materials: Infrared Cameras or Thermal Imagine
15. as moisture evaporates from materials the surface of that materials be-comes : cooler
16. is always removed in both Cat 2 & 4 water damages: -
, Carpet cushion or pad
17. Damage particle board should be and
: removed and replaced
18. This material loses most of its structural integrity when wet but regains itsstrength when
dry:: Gypsum wallboard or carpet
19. Multiple extraction passes greatly drying times: reduces
20. After physically removing excess water, the time required to dry wet mate-rials is
determined by the rate of : evaporation.
21. Waster water shall be disposed of in accordance with applicable local,state and federal
: regulations
22. The number of gallons present in standing water that is 3ft 9 inches deepin an 18 x 26
foot basement is:: 13,127.40 gallons
23. , , and , have a direct influence on
the time it takes to return wet materials to an acceptable drying goal.: Humidity,airflow and
temperature.
24. the amount of moisture in a volume of air expressed as a percentage of the maximum
amount of moisture that volume could contact at a specifiedtemperature is .: Relative
humidity %
25. As air temp increases, relative humidity : decreases
26. the ratio of the mass of water vapor to the mass of dry air in a given moistair sample,
expressed in grains per pound of dry air is:: humidity ratio (GPP)
27. As humidity ratio increases (or decreases) another psychrometric proper-ty that also
increases (or decreases) is:: dew point and vapor pressure
28. A first priority on every water loss is to conduct a: Hazard and risk assess-ment
29. All technicians required to wear respiratory protection must be:: Trained,Fitted for mask
and evaluated medically.
30. Two hazardous materials commonly found in older structures are: Lead andAsbestos
31. Water damage restoration work never begins without a signed: work autho-rization
32. To minimize
damage to building materials and contents, restorers should perform as part of the
preliminary inspection.: Loss mitigation services
33. When pre-existing damage is discovered, technicians should
and to all materially
interestedparties.: document and communicate
34. Technici
ans should always use a and a
