4. Water damage mitigation services do not start until: A work authorization
(contract) has been signed
5. During the initial inspection when looking for areas impacted by water damage::
Check all areas that could potentially be affected
6. Often found in older structres, lead and asbestos are hazardous materials
regulated by the Federal Government (true or False): True
7. The Category of water refers to the range of contamination in water considering
both its originating source and its quality after contacting materials on the
jobsite. (True or False): True
8. Water that has significant degree of contamination and could cause illiness is::
Category 2
9. Water that is grossly contaminated is:: Category 3
10. If stopped from removing highly porous materials (e.g. carpet) on a Category
3 job, what should a restorer do?: Stop work to prevent liability
11. Water that contains diesel fuel is:: regulated, Hazardous Materials or Mold
12. The three types of damage a tchnician needs to identify, document, and
communicate to materially interested parties are:: Pre-existing, primary, and
secondary
13. Secondary damage are more likely to occur when relative humidity levels
are:: 55%
14. Performing a thorough extraction or multiple extractions....: Reduces drying
times
15. Water extracted from a jobsite should be...: Disposed of according to local laws
16. In a basement that measures 25' x 30' and has water standing at a depth of 9",
how many gallons total are there?: 4,208 gallons 25 x 30 x (9/12 = 0.75) x
7.481
17. In a crawlspace that measures 12' x 15' and has water standing at a depth of
5'3", how many total gallons of water is there?: 12 x 15 x (5'3" = 5 3/12 = 5.25) x
7.481= 7,069 gallons
1/7
, 18. A moisture reading obtained from an unaffected material that allows the
restorer to set drying goals for the affected structure is the___: Dry standard
19. When is a drying job done?: A moisture meeter indicates we have met our dry
goal
20. The moisture sensor can be used to verify our drying goal has been met (True
or False): False
21. Moisture sensors and IR cameras are effective tools for:: quickly locating
moisture in carpet and pad and establishing a wet perimeter.
22. What does a thermo-hygrometer measure?: Temperature and relative humidity
23. When do (IR) infrared cameras indicate possible moisture in materials?:
Materials surface temperature cools as water evaporates. Moisture in materials can cause
temperature variations due to differences in thermal conductivity.
24. once an area is identified with an infrared camera as a suspect of being wet,
that area must be verified with:: A moisture meter or sensor
25. Psychrometric conditions have a direct effect on the rate at which moisture
moves within materials, as well as from wet materials. (True or false): True
26. What are the three things restorers can manipulate to promote drying?
(sometimes called the drying pie): Humidity, Airflow, and Temperature
27. The ratio of moisture in the air, as compared to the maximum amount the air
could hold at that temperature is...: Relative Humidity (RH)
28. What is the ratio of the weight of water vapor mixed with a specific weight of
dry air called?: Humidity Ratio
29. The ____ difference between the dew point temperature of surrounding air
and the temperature of the affected material (if warmer), the greater the potential
for drying (smaller or greater): greater
30. To promote effective drying restorers need to control:: surface temperature of
the wet materials, air temperature of the drying chamber, and vapor pressure of the drying
chamber
31. Lowering the temperature in a drying chamber my cause:: Condensation
32. If you increase the temperature in a drying chamber, relative humidity
will...: Decrease
33. Evaporation will increase when: wet materials are made warmer, when drier air is
used, and when air is moved across the wet surface.
34. At dew point temperature..: Vapor changes to a liquid
35. The movement of water vapor through a material is caused by..: vapor pressure
differentials
36. The greater the temperature of wet materials, the more energy is available for
__________ to occur.: Evaporation
