WATER RESTORATION EXAM IICRC
2026/2027 ACTUAL QUESTIONS
WITH VERIFIED ANSWERS.
Class 3 water intrusion involve the ___ amount of water
absorption with more than ___% of area surface being wet
porous materials. - correct answer-greatest
40%
wet material present in a class 4 water intrusion require a ___
time to dry. Water has saturated deeply into the materials and is
held or trapped as bound water. low evaporation material have
____ absorption of water. - correct answer-longer
significant
restorers must maintain their safety certified equipment
properly. this includes, replacing ___ that are damaged,
replacing damaged inlet and outlet ___ and checking for ___
electrical plugs. - correct answer-cords
screens
grounded
,Install _ air mover for each ________ area before you calculate
additional air movers for the square feet of surfaces and for
room offsets. - correct answer-1
affected
dehumidification reduces the _____ content of the air - correct
answer-moisture
A balanced drying system is achieved when the rate of
dehumidification is greater than or equal to the rate of
___________. - correct answer-evaporation
If the rate of evaporation is allowed to exceed the rate of
dehumidification, _________ ______ can occur. - correct
answer-secondary damage
Refrigerant dehumidifiers remove water from the air through the
process of ____ because of this fact, they are more efficient in
higher humidity conditions. refrigerants dehumidifiers work best
between 70 Degrees and 90 degrees F - correct answer-
condensation
, LGRs produce lower ______ than conventional refrigerants and
continue to remove significant water vapor down to ___GPP -
correct answer-vapor pressure
34 GPP
Because desiccant dehumidifiers do not use condensation to
remove water, they are not limited by low dew point
temperatures; therefore, they produce the lowest _____
________ of any dehumidifier. - correct answer-vapor pressure
if a structure had affected air at 85 F at 65% RH the most
efficient type of dehumidification to use would be a _______ -
correct answer-refrigerant
if a structure had affected air at 75 F at 25% RH the most
efficient type of air dehumidifier to use would be ____ - correct
answer-desiccant
if a structure cannnot be warmed to a temperature where LGRs
would be effective the most efficient type of dehumidifiers to
use would be:____ - correct answer-desiccant
