Cords Screens Grounded Install ____ air mover for each ___________ area before you calculate additional air movers for the square feet of surfaces and for room offsets. ✓ ✓ ...... ANSWER ....... 1 Affected Dehumidification reduces the _______________________ content of the air. ✓ ✓ ...... ANSWER ....... Moisture
A balanced drying system is achieved when the rate of dehumidification is greater than or equal to the rate of _____________________________. ✓ ✓ ...... ANSWER ....... Evaporation If the rate of evaporation is allowed to exceed the rate of dehumidification, ____________________ ________________ can occur. ✓ ✓ ...... ANSWER ....... Secondary Damage Refrigerant dehumidifiers remove water from the air through the process of _________________________. Because of this fact, they are more efficient in higher humidity conditions. Refrigerant dehumidifiers work best between ____° and ____° F. ✓ ✓ ...... ANSWER ....... Condensation 70° 90° Conventional refrigerant dehumidifiers under normal temperatures are effective in reducing high humidity to a normal level — approximately 40% RH, or about _______ GPP. ✓ ✓ ...... ANSWER ....... 55
If a structure cannot be warmed to a temperature where LGRs would be effective, the most efficient type of dehumidifier to use would be: refrigerant / desiccant ✓ ✓ ...... ANSWER ....... Desiccant Air filtration devices (AFDs) are needed in water restoration work whenever high levels of __________________ are being added to the air ✓ ✓ ...... ANSWER ....... Particulates To determine how many dehumidifiers to place: a. Determine the _____________ feet (meters) affected or volume of air to be dehumidified by multiplying the area's length × width × height. b. Note the dehumidifier rating (Association of Home Appliance Manufacturers, or AHAM, rating) of the refrigerant/LGR dehumidifier being used, or the process-out CFM of the desiccant dehumidifier being used. Dehumidifiers' AHAM ratings are measured in pints of water removed at _____°F, ____% RH for _____ hours.
c. Once the factor has been identified, use the following formula for LGRs and conventional refrigerants: Imperial: cubic ft. _____ factor = AHAM pints required. d. For desiccant dehumidifiers, use the formula: Imperial: factor _____ cubic ft. ÷ 60 = CFM required. e. The product of the formula represents the _______________ CFM (desiccants) or AHAM pints (refrigerants) required. This total is then compared to ✓ ✓ ...... ANSWER ....... Cubic 80 Degrees, 60%, 24 hrs Divide (/) Times (X) Total, Minimum
Refrigerant Formula (always divide) ✓ ✓ ...... ANSWER .......
- Cubic Footage ÷ Chart Factor = Total PPD (Pints Per Day) Removal Recommendation
- Total PPD Removal Recommendation ÷ Dehumidifier AHAM Rating = # of Dehumidifiers Desiccant Formula (divide by 60 for base CFM. Then multiply by ACH) ✓ ✓ ...... ANSWER ....... 1. Cubic Footage ÷ 60 × Chart Factor (ACH) = Total CFM Recommendation
- Total CFM Recommendation ÷ Dehumidifier CFM Rating =
of Dehumidifiers
A room with water damage measures 16 feet × 12 feet. Water has wetted all of the flooring in the room. The flooring is wet in an offset measuring 10 feet × 4 feet. Water is wicking up the walls less than 2 feet except for Wall A, measuring 12 feet × 8 feet.
Water came down from above to wet all of Wall A but not the ceiling. The number of air movers to install will be: ________ for the room. ________ for the floors. ________ for the walls. ________ for the offset. The total number of air movers required is ____ - ____. ✓ ✓ ...... ANSWER ....... 1 4 - 5 1 1 7 - 8 Cupping will generally be the first indication of abnormal moisture levels in hardwood flooring as the ________________ and sides of the board absorb moisture. ✓ ✓ ...... ANSWER ....... Bottom
Remove the vinyl (flooring) and discard it if the _____________________ is saturated and/or damaged; vinyl is a vapor barrier and the time required to dry underlayment will be dramatically reduced if the vinyl is removed. ✓ ✓ ...... ANSWER ....... Subfloor Partial floating of carpet can be a way to achieve drying of all surfaces simultaneously and allows _____________ dry air to have more contact with wet flooring. ✓ ✓ ...... ANSWER ....... Warm During the drying process, all of the gypsum's original strength is restored. In fact, the dried gypsum will normally be slightly _________________ than before wetting. ✓ ✓ ...... ANSWER ....... Stronger In structures where the surface of the wall is covered with a non-________________ surface as a vapor barrier, it may be necessary to remove base molding, drill holes and introduce air movement. ✓ ✓ ...... ANSWER ....... Permeable
Airflow in the wall cavity increases the rate of ____________________ and allows the wall to dry from both inside and out. ✓ ✓ ...... ANSWER ....... Evaporation When ceilings are affected, drying procedures are similar to wall drying. If the ceiling is sagging or otherwise damaged, wet drywall is drained, ________________ and _________________. ✓ ✓ ...... ANSWER ....... Removed Discarding Specific types of secondary damage associated with contents are typically:
______________________ ______________ of __________ / ____________ ✓ ✓ ...... ANSWER ....... Swelling Staining Color Transfer Delamination of Surface/Finish Material Inspections are more consistent when the overall goals are kept in mind:
a. Record of ___________________ Content (RMC) b. Moisture Map — a diagram or sketch indicating the boundaries and moisture levels of the affected area c. Record of _______________ Conditions (RDC), or Daily Humidity Record ✓ ✓ ...... ANSWER ....... Moisture Drying Once it has been determined that the floor can be salvaged by in-place drying, the first step is to determine a __________ ______ for the hardwood and subfloor. ✓ ✓ ...... ANSWER ....... Dry Standard The wood is considered dry when: a. Hardwood and subsurfaces are within ______-_____ percentage points of normal Equilibrium Moisture Content (Dry Standard).

Subsurfaces below hardwood are dried to within _____- ______ percentage points of the hardwood The most critical course of action in restorative drying is to ___________________ _______________ and begin __________________ as soon as possible. ✓ ✓ ...... ANSWER ....... Respond Quickly & Mitagation All restorers should follow the standard of care for the water restoration profession developed by the restoration industry entitled the IICRC _____________________. ✓ ✓ ......

Potentially Affected The ultimate goal is to find the "edge" of water migration, which moves in a three-dimensional path throughout the structure. This is accomplished across carpeted surfaces using a ______________ _______________, and across most hard surfaces using a ______________________________ (non- penetrating) moisture meter. ✓ ✓ ......
