IEP
Losses where regulated or hazardous materials have contaminated the structure do not change the _______ of water.
category
pre-existing conditions should be identified documented and communicated to all _________ parties during the initial inspection.
materially interested
when carpet delimitation (the loss of integrity in the adhesives used to laminate the _____ and _____ backings) has occurred, further damage is very likely. for this reason when extensive carpet delimitation is discovered technicians must call it to the attention go all materially interested parties , document the condition and suggest replacement.
primary and secondary
there are number of causes for carpet delimitation - many of them relates to ____ restoration activities
improper
Many building materials will absorb excess water vapor and suffer damage, especially when air is allowed to remain above __% relative humidity.
60%
Hygroscopic materials gain and lose moisture continually in an effort to ________ with the water content in the surrounding air mass. The more hygroscopic the material, the faster it will collect water vapor, and the easier it will suffer _________ damage.
equalize and secondary
When water intrusion results in water running through wall cavities, inspection access holes are used to ensure that blown-in insulation has not compacted and lost its ______. Wet compressed insulation should be ______
R-Value , removed
the most effective way to speed the drying process is to remove as much of the water in a liquid state as possible during the _____ phase (for example multiple extractions.) poor extractions will significant slow the drying process.
extractions
Abide by local ____ and regulations when disposing extracted water. Waste water is best disposed of into a sanitary sewer.
laws
the primary goal of the initial extraction of the affected area is to contain further ______ of the water within the structure.
migration
Whenever carpet must be disengaged from the tackless strip, a ____ ______ and carpet awl must be used.
knee kicker
the majority of cushion has a skin or mesh on the top side. the purpose of this skin is to ease_____ during installation: it is not a vapor barrier
carpet stretching
If carpet is to be re-installed, technicians should avoid cutting carpet seams unless it is absolutely
necessary
how many gallons of water are presenting a basement that measures 30' x 25' where water is standing at a depth of 6'9"
30'x25'x6.75' (9"/12") = 5062.5 cuft x 7.48= 37,867.50
every cubic foot of standing water present in a structure contains ___ gallons (28.3 liters) and each gallon (3.8 liters) of water wights 8.34pounds (3.8 kg)
7.48
there are 3 levels of biocidal activity, according to the environmental protection agency EPA( provide starting with weakest)
1. sanitizer: cleaning treatment designed to reduce # of pathogenic microorganisms to a safe level.
2. disinfectant: designed to destroy or inactivate microorganisms but not necessarily their spores
3. Sterilizer: a product designed to destroy or eliminate all forms of microorganisms (fungi, bacteria, viruses) and their spores.
whenever a chemical antimicrobial or biocide is used restorers must follow the label ____ explicitly
directions
most antimicrobials require that the area of application be vacated by ______ and pets during application and or a period of time after application.
occupants
* The label is the law" get customer briefing before starting any antimicrobial / biocide treatment.
establishing _______ is the best way to set restorative dying goals. A dry standard is established by obtaining a moisture reading using an ____ material
dry standard , unaffected
the numerical value from a moisture meter can be documented and used to monitor progress, for this reason, the amount of moisture absorbed by semiporus structural materials is measured most accurately with a moisture ______ not a moister sensor.
meter
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
a thermo hygrometer is used to monitor any air that can influence the ________ and or ______ within a restorative drying environment.
temperature , humidity (relative humidity)
to evaluate the progress of structural drying projects, restorers should measure:
moisture in ____ being dried (moisture content readings )
__ being used to dry affected materials (psychrometric readings)
__produced by mechanical systems (dehumidifiers)
materials
air
air
evaporation will increase when
wet materials are made warmer
when drier air is used
air is moved more rapidly across the wet surface
after excess water has been extracted the time needed to dry wet materials is determined by the
rate of evaporation [Show Less]
