IICRC S500 Water Mitigation Exam Practice Questions with
Correct Answers.
The homeowner - ANS is responsible to take the necessary steps to preserve and
protect their property from further damage
Four principles of water damage restoration: - ANS Provide for health and safety of
workers and occupants; Document everything; Mitigate, and Dry
Four principles of drying - ANS Extract, Evaporate, dehumidify, control temp
Extraction - ANS is removing excess water and is the first step in mitigation
Evaporation - ANS is achieved by using energy (heat) to transform water trapped in
porous materials into a vapor, thereby releasing the moisture from the materials.
Dehumidification - ANS the process of removing water vapor from the air.
Rate of Dehumidification - ANS must be at least equal to the rate of evaporation.
True or False - ANS Elevated vapor pressure in a room can cause secondary damage
to hygroscopic materials
True or False - ANS The control of temperature is important to enhance both
evaporation and dehumidification for effective drying
True or False - ANS When temperature increases evaporation of absorbed water
increases and water vapor suspended in air also increases.
Classification of Water Intrusion - ANS described as Class 1, 2, 3, or 4. Must be
determined to calculate the amount of dehumidification required in drying process,
based on the amount of wet surface area, presence/porosity of materials in drying area.
Class 1 - ANS is the least amount of water absorption and evaporation load, affecting
less 5% of porous materials with minimal absorption into low evaporation materials.
Class 2 - ANS has a significant amount of water absorption and evaporation load,
affection 5-40% porous materials, with minimal absorption into low evaporated materials
Class 3 - ANS has the greatest amount of water absorption and evaporation load,
affecting more than 40% porous materials and minimal absorption into low evaporated
materials
Class 4 - ANS has deeply held or bound water, and significant absorption into low
evaporation materials.
, Determine the Class of water for a 20' x 20' x 8 ' room, with an entirely wet floor... - ANS
Affected area/Total SF = % affected
400/1440 = .27777 x 100 = 28%
28% = Class 2
Determine the Class of Water for a 20' x 20' x 8' room, with only half the floor affected
and arriving within 24 hours of loss. - ANS Affected area/total so = % affected
200/1440 = .13888 x 100 = 14%
14% = Class 2
Determine Class of water for a 20' x 20' x 8' room, with entirely wet plywood subfloor
arriving 48 hours after loss - ANS affected area/total so = % affected
Class 4 due to deeply bound water sitting for long time
Categories of Water - ANS there are four categories - determined by range of
contamination of the source and quality of water
Category 1 water - ANS Water originating from sanitary water source, with no
deterioration, does not pose risk to skin or if ingested
Category 2 Water - ANS Water containing significant contamination from materials,
unsafe levels of microorganisms, causes discomfort or sickness.
Category 3 Water - ANS Water grossly contaminated with pathogens, toxins, bacteria,
and causes sickness
Regulated or Hazardous Material and Mold - ANS the last category of water, without
number designation, requiring a specialized environmental expert (EIP) to assist where
government regulations apply.
The ANSI/IICRC S500 - ANS Is the standard of care for the water damage restoration
industry, providing foundation for basic principles of proper restoration practices.
When the ANSI/IICRC S500 uses the word "Shall" it means - ANS it is something
mandatory due to laws/regulations
When the ANSI/IICRC S500 uses the word "Should" it means - ANS it is something that
is mandatory but not due to laws
When the ANSI/IICRC S500 uses the word "Recommended" it means - ANS it is
something that is advised or suggested to do
Psychometric - ANS the study of the relationship between air, humidity, temperature
and their effects on various materials
