Answers-surface temperatures of affected materials
.#5. Water damage restoration services should not begin until after the: - Answers-
restorer has entered into an adequately written contract.
.#6. Two tools that should be used to properly disengage most stretched-in carpet -
Answers-Knee kicker and carpet awl
.#7. When inspecting a water damage structure, restorers should inspect: - Answers-all
potentially affected areas.

used to evaluate and document: - Answers-applicable psychrometric conditions and
moisture content or level readings .

regains its strength when dry, is: - Answers-Concrete
.#11 Initially, a method of search for abnormal moisture behind ceramic tile or resilient
flooring can be accomplished by - Answers-using a non-penetrating (non-invasive)
moisture meter
, .#12. To minimize damage and reduce drying time, reduce drying time, restorers
should: - Answers-begin mitigation as soon as safely possible
.#13. The moisture content of structural materials should be measured with a -
Answers-A. moisture meter

restorers can: - Answers-B. install one or more air filtration devices (AFDs)
.#18. When pre-existing damage is discovered, restorer should - Answers-D. document
and bring it to the attention of materially interested parties
.#19. Rapid drying of structural materials is achieved by - Answers-A. promoting
evaporation and dehumidification or ventilation
.#20. When carpet and cushion (pad, underlay) are saturated with Category 3 water -
Answers-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 - Answers-A. drained,
removed quickly, and properly disposed
.#22. The force exerted by water molecules in the air on surrounding surfaces is -
Answers-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 - Answers-A. 60F (4C) and 80%
RH
.#24. Two hazardous materials more likely found in older building that require
compliance with laws and regulations when handled are - Answers-C. lead-based paint
and asbestos
