IICRC Water Restoration Technician

IICRC Water Restoration Technician - Penetrating measure meter measures - Suggested temp for dry bulb 70-85 degrees Below 70 can slows above 1 - How many air movers are installed in each affected room to start? 7.48 - How many gallons are in a cubic foot of water? 20% moisture content and above - What moisture content in wood can support "wood rot"? 29% - If the humidity ratio is 45GPP at 80°F... What is the relative humidity? 30-50 - Acceptable range for an indoor relative humidity 38,148 - How many gallons are in a basement that is 40' x 30' with a 4'3" water depth? 40 F/40% - Considering the following measurements, which is the lowest humidity ratio (or dewpoint temperature or vapor pressure) 90F/30% OR 40F/40% OR 50 F/80% OR 70 F/70% 50 to 70 - Add one air mover for every "how many" square feet of floor (including 2 feet up walls)? 60 - Inside of the house is 75°F and 60% relative humidity. How cold is the windows have to be in order to collect condensation? 60% - A healthy relative humidity should not exceed 60% - Indoor RH should not exceed 70 F/70% - Considering the following measurements, which is the highest humidity ratio (or dewpoint temperature or vapor pressure) 90F/30% OR 40F/40% OR 50 F/80% OR 70 F/70% 70 to 90°F - What temperature range do refrigerant dehumidifiers work best in? 70% - What relative humidity (and above) can support microbial growth? 89-85% - Adhesives losses what perfect of stretch when wet 92 - At 70°F and 60% relative humidity... What temperature is required to bring relative humidity to 30%? 100 to 150 - Add another air mover for every "how many" square feet for wet walls above 2 feet high? 100% RH - When does humidity become saturated 333 - How much initial pints of Dehumidification does the IICRC recommend for a class 3, conventional dehumidifier at 10000 cubic feet? 500 - How much initial pints of Dehumidification does the IICRC recommend for a class 2, LG dehumidifier at 25000 cubic feet? 750 - How much initial CFM of Dehumidification does the IICRC recommend for a class 4, desiccant dehumidifier at 15000 cubic feet? Above 60% - When can secondary damage occur Above 70 - What temperature will increase the rate of drying Advise parties to gain permission - What must be due before we apply biocide into a structure? After acclimation - When can you refinish the hardwood floor? Aid abs install - Purpose or carpet cushion Air warmer and dryer and extraction - What can be don't you decrease drying time Air, humidity and temperature - Psychometry is the study of Always - When is mechanical dehumidification necessary? ANSI/IICRC S-500 Water Damage Standards - What document dictates the Standards for the Water Damage Restoration Industry? Areas of high vapor pressure seeks areas of low vapor pressure - What does it mean when we say, "nature always seeks an equilibrium?" At the start of the job - When should you establish hardwood floor drying goals? atleast 20 degrees - How many degrees above dewpoint for drying Atmospheric temperature changes/humidity ratio changes (including mechanical devices)/material moisture changes/material temperature changes - What measures to daily drying data include? Back into sanitary sewer - Where do we dispose of the water we collect on the water damage loss? Between 5 to 40% of materials are affected - What is a Class 2 water loss? Can be dried - Materials above the dewpoint Category 2 & Category 3 - What is the carpet cushion always get replaced? Condensation occurs, evaporation stops - What happens if the material is cooler than the dewpoint temperature? Cooler because the molecules absorb energy - When water evaporates, does the surface become cooler or hotter? Why? cubic feet, class, dehumidifier type - The IICRC formula requires three things to determine the initial D humidification needs... What are they? Cupping - What is a hardwood floor that is water on the bottom and the top look like? Daily - How often should we inspect restorat
