A clear communication structure or "tree" should be established... - ANS Prior
to the job start-up (who? How? How often? Who not to chat with)

A common means of providing return air to the air handling unit in a commercial
system is through: - ANS the space above a suspended ceiling
A confined space is defined as what 3 things...? - ANS (1) having limited or
restricted means of entry or exit; (2) is large enough for a person to enter and
perform tasks and (3) is not designed for continuous occupancy.
A confined space you might encounter in a multi-story office building is: - ANS
an elevator pit
A dry standard is... - ANS a reasonable approximation of the moisture content
or level of a material prior to a water intrusion"
A heat-drying system includes: - ANS heating apparatus, delivery systems and
means of exhausting moisture laden air from building
A quicker and more practical method of evaluating the vapor differential in a drying
environment is by... - ANS comparing the difference between the dew point of
the air and the surface temperature of the materials.
A refrigerant-based dehumidifier (aka DX air conditioning system) works by -
ANS Circulating a refrigerant gas through a cold coil which chills the airstream
below the dew point, thus removing moisture.
A requirement after penetrating fire-rated walls... - ANS properly repair walls in
order to maintain their fire-rating
,IICRC
A structure used primarily for retail, office, mixed-use and warehousing is - ANS
commercial
a successfully-managed project is one in which you complete the scope of work
within... - ANS the agreed upon timeframe and budget
Absolute expressions of the moisture content of air at a given atmospheric pressure
include humidity ratio, dew point and... - ANS vapor pressure
According to OSHA, what are the three conditions that define a "confined space"? -
ANS 1. Limited means of entry and exit 2. Large enough for a person to enter and
work 3. Not designed for continuous occupancy
According to the current IICRC S500 Standard, a restorer should establish an initial
dehumidification capacity needed on a project, but should be modified after that
based on... - ANS subsequent / following days of psychometric meetings
Additional sensible energy (heat) is usually a beneficial by-product of: - ANS a
desiccant dehumidifier
Air that is 50%RH at 95°F (35°C) has an enthalpy of: - ANS 42.5 btu/lb
An Emergency Action Plan (EAP) is required - ANS on every job
An employer shall provide to each of his employees a place of employment that is: -
ANS Free from recognized hazard
An energy management system's (EMS) primary purpose is to: - ANS
conserve energy
Are Class1/2/3 different than Class 4...? If so, how? - ANS Class 1/2/3 = the
amount of water evaporating from porous surfaces, while Class 4 describes how
slowly water will migrate through thick, dense materials. Bound moisture in "low
evaporation materials" migrate very slowly, requiring a different strategy.
Areas you are likely to find multiple layers of drywall are... - ANS school
hallways, technical rooms, elevator shafts

increases
, IICRC
Based on the 80% rule... you can run how many amps on a 150 amp breaker? -
ANS 120 amps
Can E Management systems impact drying...? - ANS If not controlled or
temporarily turned off, any of these systems could negatively impact your drying
effort. An additional issue is that they are often managed off-site. Only a building
engineer will be able to control it.
Chiller-water systems circulate conditioned water (chilled or heated) through the
system that is distributed to... - ANS ... individual fan/coil units located in the
building
Classes of water for to... - ANS the amount of water absorption and
evaporation load Class 1 = least, less than 5% // Class 2 = significant, 5-40% //
Class 3 = greatest, more than 40% // Class 4 = deeply held or bound water
