IICRC WATER RESTORATION COURSE
2026/2027 ACTUAL QUESTIONS WITH
VERIFIED ANSWERS.
Conventional refrigerant dehumidifiers under normal
temperatures are effective in reducing high humidity to a
normal level approximately 40% RH or about 55 gpp - correct
answer-
LGR will continue to remove significant water vapor down 34
gpp - correct answer-
Because desiccant dehumidifiers do not use condensation to
remove water they are not limited by the low dew point
temperatures therefore they produce the lowest vapor pressure
of any dehumidifier - correct answer-
When's the next been determined that the floor can be
salvaged by in place drying the first step is to determine a dry
standard for the hardwood and subfloor - correct answer-
,Equilibrium moisture content - correct answer-is the dry
standard
Hardwood and sub surfaces are within two to four percentage
points of normal equilibrium moisture content dry standard -
correct answer-
Subsurface is below hardwood are dried two within two to four
percentage points of the hardwood - correct answer-
After wood flooring has been dried to acceptable moisture
content appropriate acclimation time should be allowed before
refinishing - correct answer-
Moisture documentation of restoration work should include
each of the following components - correct answer-record of
moisture content moisture map a diagram or sketch indicating
the boundaries and moisture levels of the affected area and
record of drying conditions or humidity record
, The best way to prevent odors and retard microbial growth in a
wet structure is to ensure that all materials are dried thoroughly
and rapidly - correct answer-
As mold grows it can produce a toxic chemical substance all
mold rated toxins are referred to as - correct answer-
mycotoxins
When the presence of mold is suspected it is important to
communicate with all parties and use appropriate - correct
answer-protective measures
As with any contaminant mold should be removed or contained
before any air movers are placed in the structure blowing air
can spread mold spores and contaminate the entire area -
correct answer-
Dry rot wood rot can occur when wood is visibly dry it wetter
than 20% moisture content - correct answer-
