IICRC S500 Water Mitigation Exam
Questions & Answers (Grade A+)
The homeowner -
correct answer ✅is responsible to take the necessary steps to
preserve and protect their property from further damage
Four principles of water damage restoration: -
correct answer ✅Provide for health and safety of workers and
occupants; Document everything; Mitigate, and Dry
Four principles of drying -
correct answer ✅Extract, Evaporate, dehumidify, control temp
Extraction -
correct answer ✅is removing excess water and is the first step in
mitigation
Evaporation -
correct answer ✅is achieved by using energy (heat) to transform
water trapped in porous materials into a vapor, thereby releasing
the moisture from the materials.

Questions & Answers (Grade A+)
Dehumidification -
correct answer ✅the process of removing water vapor from the
air.
Rate of Dehumidification -
correct answer ✅must be at least equal to the rate of evaporation.
True or False -
correct answer ✅Elevated vapor pressure in a room Can cause
secondary damage to hygroscopic materials
True or False -
correct answer ✅The control of temperature is important to
enhance both evaporation and dehumidification for effective drying
True or False -
correct answer ✅When temperature increases evaporation of
absorbed water increases and water vapor suspended in air also
increases.
Classification of Water Intrusion -
correct answer ✅described as Class 1, 2, 3, or 4. Must be

Questions & Answers (Grade A+)
determined to calculate the amount of dehumidification required in
drying process, based on the amount of wet surface area,
permeance/porosity of materials in drying area.
Class 1 -
correct answer ✅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 -
correct answer ✅has a significant amount of water absorption and
evaporation load, affection 5-40% porous materials, with minimal
absorption into low evaporated materials
Class 3 -
correct answer ✅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 -
correct answer ✅has deeply held or bound water, and significant
absorption into low evaporation materials.
