WATER RESTORATION exam IICRC

WATER RESTORATION exam IICRC Elaborated 100% ____ drying systems merge the benefit of both open and closed drying: the use of available dry air from outside and the control offered by a closed system and mechanical dehumidification - combination ____ is the temperature at which air becomes saturated with moisture and can hold no more water vapor - dew point ____ occurs when a solid changes to a vapor( without going through a liquid phase.) - sublimation ____ represents the "was-wood" material with the least engineering , and thus the most natural fiber bonding. it is ___to swelling and delimitation due to its wood veneer assemblies which are glued under extreme pressure. - plywood , resistant _____ occurs when liquid changes to a vapor. occurs as energy is increased - evaporation ______ is defined as the amount of moisture contained in an air sample as compared to the maximum amount the air could hold at the temperature. - relative humidity ______is the force exerted by a gas (vapor molecules) on the surrounding environment. - vapor pressure ___. occurs when vapor changes to a liquid. occurs as energy is removed - condensation * The label is the law" get customer briefing before starting any antimicrobial / biocide treatment. - A balanced drying system is achieved when the rate of dehumidification is greater than or equal to the rate of ___________. - evaporation a thermo hygrometer is used to monitor any air that can influence the ________ and or ______ within a restorative drying environment. - temperature , humidity (relative humidity) Abide by local ____ and regulations when disposing extracted water. Waste water is best disposed of into a sanitary sewer. - laws after excess water has been extracted the time needed to dry wet materials is determined by the - rate of evaporation After safety concerns have been addressed and the initial water source has been stopped, the restorer must complete an evaluation of the water's migration through the structure. During this process, the restorer inspects all ___________ ________ areas. - potentially affected air filtration device (AFDs) are needed in water restoration work whenever high levels of ____ are being added to the air - particulates Airflow in the wall cavity increases the rate of ___________ and allows the wall to dry from both inside and out. - evaporation All restorers should follow the standard of care for the water restoration profession developed by the restoration industry entitled the IICRC ____. - s500 As moisture evaporates from a wet material, the surface of the material becomes ______ because energy is released from the material. - cooler as the water has been extracted the time needed to dry wet material is determined by the - rate of evaporation As the water is rapidly evaporated, the water vapor is removed by ________________ or ___________. - 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 from the ______ area to the _____ rooms - contaminated , unaffected Because desiccant dehumidifiers do not use condensation to remove water, they are not limited by low dew point temperatures; therefore, they produce the lowest _____ ________ of any dehumidifier. - vapor pressure 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 as ______ and resilient ____ floor coverings. - ceramic tile , vinyl class 1 water intrusions involve the ____ amount of water absorption, with less than __ % of the area surface being wet porous materials. - least , 5% class 2 water intrusions involve a _____ amount of water absorption, with more than ___ but less than ___ of are surface being wet porous materials - significant 5%-40% Class 3 water intrusion involve the ___ amount of water absorption with more than ___% of area surface being wet porous materials. - greatest 40% cleaning procedures must be employed before the dryi
