IICRC Water Restoration Course
a balance drying system is achieved when the rate of the vacation is greater than or
equal to the rate of - ANS evaporation
a thermo hygrometer is used to monitor any air that can influence the - ANS
temperature and humidity within a restorative drying environment
abide by local laws and regulations when disposing extracted water ways water is
best disposed of into a sanitary sewer - ANS
after physically removing excess water the time required to dry wet materials is
influenced most by the - ANS rate of evaporation
after safety concerns have been addressed and the initial water source has been
stopped the restore must complete an evaluation of the waters migration through the
structure during this process to restore inspects all - ANS potentially affected
areas
after wood flooring has been dried to acceptable moisture content appropriate
acclimation time should be allowed before refinishing - ANS
air filtration devices are needed in water restoration work whenever high levels -
ANS particulates are being added to the air
air flow in the wall cavity increases the rate of evaporation and allows the wall to
drive from both inside and out - ANS
as a minimum medical requirement technicians performing water damage restoration
services need medical consultation with their - ANS primary health care
physician for appropriate immunizations
as moisture evaporates from a wet material the surface of the material becomes -
ANS cooler because energy is released from the material
as mold grows it can produce a toxic chemical substance all mold rated toxins are
referred to as - ANS mycotoxins
as the water is rapidly evaporated the vapor water is removed by - ANS
dehumidification or ventilation
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 - ANS

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 - ANS
because of their non-invasive nature and quick surveying capabilities non-invasive
meters are the most effective tools for locating abnormal moisture behind and
beneath finishing materials such - ANS ceramic tile and vinyl floor coverings
class 1 - ANS intrusions involve only a part of an area or involve a larger area
that is only being lately affected
Class 2 - ANS what are intrusions involve damage to significant areas of
carpet and cushion includes wet carpet cushion and water wicking up gypboard
wallboard
class 3 - ANS what are intrusions involve entire areas of carpet and underlay
that are wet together with wet walls structure and insulation moisture wicking up or
water coming down from above
class 4 - ANS water intrusion results in a specialty drying situation water has
saturated deeply into the materials and is held is bound water commonly includes
hardwood plaster brick deeply saturated concrete deeply saturated ground soil and
Stone
cleaning procedures must be employed before the drying of a category 2 water loss
can continue at minimum affected underlay must be removed and disposed of and
the carpet must be thoroughly cleaned using a hot water extraction method -
ANS
condensation is vapor changing to a liquid - ANS
condensation occurs when a vapor changes to a - ANS liquid occurs as
energy is removed
conventional refrigerant dehumidifiers under normal temperatures are effective in
reducing high humidity to a normal level approximately 40% RH or about 55 gpp -
ANS
cupping will generally be the first indication of abnormal moisture levels in hardwood
flooring as the bottom and sides of the board absorb moisture - ANS cupping
in hardwood is not permanent damage and should be dried in most cases
