The homeowner - is responsible to take the necessary steps to preserve and protect their property from further damage
Four principles of water damage restoration: - Provide for health and safety of workers and occupants; Document everything; Mitigate, and Dry
Four principles of drying - Extract, Evaporate, dehumidify, control temp
Extraction - is removing excess water and is the first step in mitigation
Evaporation - is achieved by using energy (heat) to transform water trapped in porous materials into a vapor, thereby releasing the moisture from the materials.
Dehumidification - the process of removing water vapor from the air.
Rate of Dehumidification - must be at least equal to the rate of evaporation.
True or False - Elevated vapor pressure in a room Can cause secondary damage to hygroscopic materials
True or False - The control of temperature is important to enhance both evaporation and dehumidification for effective drying
True or False - When temperature increases evaporation of absorbed water increases and water vapor suspended in air also increases.
Classification of Water Intrusion - 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, permeance/porosity of materials in drying area.
Class 1 - 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 - has a significant amount of water absorption and evaporation load, affection 5-40% porous materials, with minimal absorption into low evaporated materials
Class 3 - has the greatest amount of water absorption and evaporation load, affecting more than 40% porous materials and minimal absorption into low evaporated
