ALREADY GRADED A+ ASSURED PASS
Terms in this set (130)
1. Removing Materials to eliminate safety hazards
2. Removing materials that have
suffered primary damage and are not
restorable
3. Removing porous materials that are holding odor
5. Removing vapor barriers to assist with drying
efforts
6. Removing materials to reduce drying time
Why does demolition 7. Removing materials to open cavities or
occur
areas to provide additional needed
services
Useful for adjuster, or notes on xactimate line
items
Step 1: Install One air mover in each affected
Room
Step 2: Add one air mover for every 50-70 square
feet of affected wet floor in each room
Step 3. Add one air mover for every 100 - 150
square feet of affected wet ceiling and wall areas
Recommendation above approximately 24"
Calculation Step 4: Add one air mover for each wall inset and
offset greater than 18" Step 5: Total x - y
This is the Recommendation Calculation
Air Filtration Device Commonly called an air scrubber or negative air
(ADF) machine if airborne particles
need to be reduced, you could use an appropriately
installed _______ ________ ________

Air Filtration Device AFD
Prior to determining the best drying system
Assembly Construction for affected materials, restorers should
identify and understand the assembly
construction (ie wall assembly, floor
assembly)
water originates from a sanitary source and
Category 1 does not pose substantial risk for dermal,
ingestion, inhalation, or exposure.
Uncontaminated and routinely
cleaned
Category 2 water contains significant contamination and
has the potential to cause discomfort or
sickness if contacted or consumed by
humans

Category 3 water is grossly contaminated and can
contain pathogenic, toxigenic, or other
harmful agents
Sewage Back Up Category 3
Clean water supply line Category 1
Class 1 Least amount of water absorption and evaporation
load - Wet porous materials
- water loss is less then 5% of the area
Class 2 Significant amount of water absorption and
evaporation load - water intrusion where
wet represents 5% - 40% of the area.
Class 3 greatest amount of water absorption and
evaporation load. Water intrusion where
wet represents over 40% of the area
deeply held or bound water. Significant
Class 4 amount of water absorption into low
evaporation materials. Drying may require
special drying methods, longer
drying time, or substantial water vapor pressure
differentials.
Uses mechanical dehumidification and is not open to
Closed drying system outside air. Used if there
are security issues, the outside air is not
conductive to drying or when access to
outside air is not possible.
Removes water vapor from the air by
Conventual refrigerant lowering the temperature of the incoming air
dehumidifier
to below dew point and causing the water
to condense on the coils. Cold
and hot surfaces created with gases inside a closed
coil system.
uses some outdoor air with dehumidifiers to
Combination Drying accelerate the drying process. This can
System
include periodically venting (flushing) the
structure, using negative pressure or using
small openings to the outside
