IICRC S500 Water Mitigation Questions and Answers!!!

IICRC S500 Water Mitigation Questions and Ans The homeowner - ANSWERis responsible to take the necessary steps to preserve and protect their property from further damage Four principles of water damage restoration: - ANSWERProvide for health and safety of workers and occupants; Document everything; Mitigate, and Dry Four principles of drying - ANSWERExtract, Evaporate, dehumidify, control temp Extraction - ANSWERis removing excess water and is the first step in mitigation Evaporation - ANSWERis achieved by using energy (heat) to transform water trapped in porous materials into a vapor, thereby releasing the moisture from the materials. Dehumidification - ANSWERthe process of removing water vapor from the air. Rate of Dehumidification - ANSWERmust be at least equal to the rate of evaporation. True or False - ANSWERElevated vapor pressure in a room Can cause secondary damage to hygroscopic materials True or False - ANSWERThe control of temperature is important to enhance both evaporation and dehumidification for effective drying True or False - ANSWERWhen temperature increases evaporation of absorbed water increases and water vapor suspended in air also increases. Classification of Water Intrusion - ANSWERdescribed 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, permeance/porosity of materials in drying area. Class 1 - ANSWERis the least amount of water absorption and evaporation load, affecting less 5% of porous materials with minimal absorption into low evaporation materials. Class 2 - ANSWERhas a significant amount of water absorption and evaporation load, affection 5-40% porous materials, with minimal absorption into low evaporated materials Cwers!!!
